【RabbitMQ】 RabbitMQ安装

　　MQ全称为Message Queue, 消息队列（MQ）是一种应用程序对应用程序的通信方法。应用程序通过读写出入队列的消息（针对应用程序的数据）来通信，而无需专用连接来链接它们。消息传递指的是程序之间通过在消息中发送数据进行通信，而不是通过直接调用彼此来通信，直接调用通常是用于诸如远程过程调用的技术。排队指的是应用程序通过 队列来通信。队列的使用除去了接收和发送应用程序同时执行的要求

Linux下安装RabbitMQ

　　环境：Linux(CentOS 7.2)

　　1、安装Erlang环境，Erlang版本是21.1。参考【Erlang】源码安装

　　2、下载源码包（rabbitmq-server-generic-unix-3.7.9.tar.xz），版本：3.7.9

　　　　官网地址：https://www.rabbitmq.com

　　　　下载地址：https://www.rabbitmq.com/download.html

　　　　

　　　　 

　　3、解压，命令：tar -xvf rabbitmq-server-generic-unix-3.7.9.tar.xz，解压后文件目录如下：
　　　　

　　　　其中sbin目录下文件说明：

　　　　rabbitmq-env 　　　　// 环境配置脚本
　　　　rabbitmq-defaults 　   // 默认参数设置脚本
　　　　rabbitmqctl 　　　　　// 管理工具脚本
　　　　rabbitmq-plugins 　　// 插件管理工具脚本
　　　　rabbitmq-server 　　 // rabbitmq服务脚本

　　4、可以自由拷贝解压后的文件到的制定目录，然后配置环境变量

　　　　a、编辑文件/etc/profile，命令：vim /etc/profile；增加如下内容：

export RABBIT_HOME=/data/soft/rabbitmq_server-3.7.9
export PATH=$RABBIT_HOME/sbin:$PATH 

　　　　b、使环境变量生效，命令：source /etc/profile。

　　5、操作服务，启动默认监听端口：5672

　　　　启动服务（前台启动）：rabbitmq-server start

　　　　启动服务（后台启动）：rabbitmq-server start -detached

　　　　重启服务：rabbitmq-server restart

　　　　关闭服务：rabbitmqctl stop 

　　　　查看服务状态：rabbitmqctl status

　　　　查看mq用户：rabbitmqctl list_users

　　　　查看用户权限：rabbitmqctl list_user_permissions guest

　　　　新增用户： rabbitmqctl add_user admin 123456

　　　　赋予管理员权限：rabbitmqctl set_user_tags admin administrator 

　　　　分配权限：rabbitmqctl set_permissions -p / admin '.*' '.*' '.*'

　　　　效果图如下：

　　　　a、启动命令
　　　　

　　　　b、查看状态

　　　　

　　　　c、查看日志配置文件为空

　　　　

　　　　注意：a、启动报错：Error description:  noproc。

　　　　　　　　解决方案：Erlang版本和RabbitMQ不支持的原因，应该安装对应版本。参考地址：https://www.rabbitmq.com/which-erlang.html

　　6、启用插件，RabbitMQ的web控制台，命令：rabbitmq-plugins enable rabbitmq_management，然后重启RabbitMQ服务

　　　　

　　7、浏览器输入http://ip:15672，端口是15672，访问RabbitMQ的web控制台，默认用户名/密码：guest/guest。

　　　默认情况下，RabbitMQ的默认的guest用户只允许本机访问

　　　由于不是在本机上访问报错，如下：

　　　　

　　8、通过 find / -name rabbitmq-defaults 查找rabbitmq-defaults文件（/data/soft/rabbitmq_server-3.7.9/sbin/rabbitmq-defaults），查看config文件的存储路径

　　　　a、下载模版，配置文件模版下载：https://github.com/rabbitmq/rabbitmq-server/blob/master/docs/rabbitmq.conf.example

## http://rabbitmq.com/documentation.html for documentation ToC.

## Networking
## ====================
##
## Related doc guide: http://rabbitmq.com/networking.html.
##
## By default, RabbitMQ will listen on all interfaces, using
## the standard (reserved) AMQP 0-9-1 and 1.0 port.
##
# listeners.tcp.default = 5672


## To listen on a specific interface, provide an IP address with port.
## For example, to listen only on localhost for both IPv4 and IPv6:
##
# IPv4
# listeners.tcp.local    = 127.0.0.1:5672
# IPv6
# listeners.tcp.local_v6 = ::1:5672

## You can define multiple listeners using listener names
# listeners.tcp.other_port = 5673
# listeners.tcp.other_ip   = 10.10.10.10:5672


## TLS listeners are configured in the same fashion as TCP listeners,
## including the option to control the choice of interface.
##
# listeners.ssl.default = 5671

## Number of Erlang processes that will accept connections for the TCP
## and TLS listeners.
##
# num_acceptors.tcp = 10
# num_acceptors.ssl = 1


## Maximum time for AMQP 0-8/0-9/0-9-1 handshake (after socket connection
## and TLS handshake), in milliseconds.
##
# handshake_timeout = 10000

## Set to 'true' to perform reverse DNS lookups when accepting a
## connection. Hostnames will then be shown instead of IP addresses
## in rabbitmqctl and the management plugin.
##
# reverse_dns_lookups = true

##
## Security, Access Control
## ==============
##

## Related doc guide: http://rabbitmq.com/access-control.html.

## Select an authentication/authorisation backend to use.
##
## Alternative backends are provided by plugins, such as rabbitmq-auth-backend-ldap.
##
## NB: These settings require certain plugins to be enabled.
##
## Related doc guides:
##
##  * http://rabbitmq.com/plugins.html
##  * http://rabbitmq.com/access-control.html
##

# auth_backends.1   = rabbit_auth_backend_internal

## uses separate backends for authentication and authorisation,
## see below.
# auth_backends.1.authn = rabbit_auth_backend_ldap
# auth_backends.1.authz = rabbit_auth_backend_internal

## The rabbitmq_auth_backend_ldap plugin allows the broker to
## perform authentication and authorisation by deferring to an
## external LDAP server.
##
## Relevant doc guides:
##
## * http://rabbitmq.com/ldap.html
## * http://rabbitmq.com/access-control.html
##
## uses LDAP for both authentication and authorisation
# auth_backends.1 = rabbit_auth_backend_ldap

## uses HTTP service for both authentication and
## authorisation
# auth_backends.1 = rabbit_auth_backend_http

## uses two backends in a chain: HTTP first, then internal
# auth_backends.1   = rabbit_auth_backend_http
# auth_backends.2   = rabbit_auth_backend_internal

## Authentication
## The built-in mechanisms are 'PLAIN',
## 'AMQPLAIN', and 'EXTERNAL' Additional mechanisms can be added via
## plugins.
##
## Related doc guide: http://rabbitmq.com/authentication.html.
##
# auth_mechanisms.1 = PLAIN
# auth_mechanisms.2 = AMQPLAIN

## The rabbitmq-auth-mechanism-ssl plugin makes it possible to
## authenticate a user based on the client's x509 (TLS) certificate.
## Related doc guide: http://rabbitmq.com/authentication.html.
##
## To use auth-mechanism-ssl, the EXTERNAL mechanism should
## be enabled:
##
# auth_mechanisms.1 = PLAIN
# auth_mechanisms.2 = AMQPLAIN
# auth_mechanisms.3 = EXTERNAL

## To force x509 certificate-based authentication on all clients,
## exclude all other mechanisms (note: this will disable password-based
## authentication even for the management UI!):
##
# auth_mechanisms.1 = EXTERNAL

## This pertains to both the rabbitmq-auth-mechanism-ssl plugin and
## STOMP ssl_cert_login configurations. See the RabbitMQ STOMP plugin
## configuration section later in this file and the README in
## https://github.com/rabbitmq/rabbitmq-auth-mechanism-ssl for further
## details.
##
## To use the TLS cert's CN instead of its DN as the username
##
# ssl_cert_login_from   = common_name

## TLS handshake timeout, in milliseconds.
##
# ssl_handshake_timeout = 5000


## Password hashing implementation. Will only affect newly
## created users. To recalculate hash for an existing user
## it's necessary to update her password.
##
## To use SHA-512, set to rabbit_password_hashing_sha512.
##
# password_hashing_module = rabbit_password_hashing_sha256

## When importing definitions exported from versions earlier
## than 3.6.0, it is possible to go back to MD5 (only do this
## as a temporary measure!) by setting this to rabbit_password_hashing_md5.
##
# password_hashing_module = rabbit_password_hashing_md5

##
## Default User / VHost
## ====================
##

## On first start RabbitMQ will create a vhost and a user. These
## config items control what gets created.
## Relevant doc guide: http://rabbitmq.com/access-control.html
##
# default_vhost = /
# default_user = guest
# default_pass = guest

# default_permissions.configure = .*
# default_permissions.read = .*
# default_permissions.write = .*

## Tags for default user
##
## For more details about tags, see the documentation for the
## Management Plugin at http://rabbitmq.com/management.html.
##
# default_user_tags.administrator = true

## Define other tags like this:
# default_user_tags.management = true
# default_user_tags.custom_tag = true

##
## Additional network and protocol related configuration
## =====================================================
##

## Set the default AMQP 0-9-1 heartbeat interval (in seconds).
## Related doc guides:
##
## * http://rabbitmq.com/heartbeats.html
## * http://rabbitmq.com/networking.html
##
# heartbeat = 60

## Set the max permissible size of an AMQP frame (in bytes).
##
# frame_max = 131072

## Set the max frame size the server will accept before connection
## tuning occurs
##
# initial_frame_max = 4096

## Set the max permissible number of channels per connection.
## 0 means "no limit".
##
# channel_max = 128

## Customising TCP Listener (Socket) Configuration.
##
## Related doc guides:
##
## * http://rabbitmq.com/networking.html
## * http://www.erlang.org/doc/man/inet.html#setopts-2
##

# tcp_listen_options.backlog = 128
# tcp_listen_options.nodelay = true
# tcp_listen_options.exit_on_close = false
#
# tcp_listen_options.keepalive = true
# tcp_listen_options.send_timeout = 15000
#
# tcp_listen_options.buffer = 196608
# tcp_listen_options.sndbuf = 196608
# tcp_listen_options.recbuf = 196608

##
## Resource Limits & Flow Control
## ==============================
##
## Related doc guide: http://rabbitmq.com/memory.html.

## Memory-based Flow Control threshold.
##
# vm_memory_high_watermark.relative = 0.4

## Alternatively, we can set a limit (in bytes) of RAM used by the node.
##
# vm_memory_high_watermark.absolute = 1073741824

## Or you can set absolute value using memory units (with RabbitMQ 3.6.0+).
## Absolute watermark will be ignored if relative is defined!
##
# vm_memory_high_watermark.absolute = 2GB
##
## Supported units suffixes:
##
## kb, KB: kibibytes (2^10 bytes)
## mb, MB: mebibytes (2^20)
## gb, GB: gibibytes (2^30)



## Fraction of the high watermark limit at which queues start to
## page message out to disc in order to free up memory.
## For example, when vm_memory_high_watermark is set to 0.4 and this value is set to 0.5,
## paging can begin as early as when 20% of total available RAM is used by the node.
##
## Values greater than 1.0 can be dangerous and should be used carefully.
##
## One alternative to this is to use durable queues and publish messages
## as persistent (delivery mode = 2). With this combination queues will
## move messages to disk much more rapidly.
##
## Another alternative is to configure queues to page all messages (both
## persistent and transient) to disk as quickly
## as possible, see http://rabbitmq.com/lazy-queues.html.
##
# vm_memory_high_watermark_paging_ratio = 0.5

## Selects Erlang VM memory consumption calculation strategy. Can be `allocated`, `rss` or `legacy` (aliased as `erlang`),
## Introduced in 3.6.11. `rss` is the default as of 3.6.12.
## See https://github.com/rabbitmq/rabbitmq-server/issues/1223 and rabbitmq/rabbitmq-common#224 for background.
# vm_memory_calculation_strategy = rss

## Interval (in milliseconds) at which we perform the check of the memory
## levels against the watermarks.
##
# memory_monitor_interval = 2500

## The total memory available can be calculated from the OS resources
## - default option - or provided as a configuration parameter.
# total_memory_available_override_value = 2GB

## Set disk free limit (in bytes). Once free disk space reaches this
## lower bound, a disk alarm will be set - see the documentation
## listed above for more details.
##
## Absolute watermark will be ignored if relative is defined!
# disk_free_limit.absolute = 50000

## Or you can set it using memory units (same as in vm_memory_high_watermark)
## with RabbitMQ 3.6.0+.
# disk_free_limit.absolute = 500KB
# disk_free_limit.absolute = 50mb
# disk_free_limit.absolute = 5GB

## Alternatively, we can set a limit relative to total available RAM.
##
## Values lower than 1.0 can be dangerous and should be used carefully.
# disk_free_limit.relative = 2.0

##
## Clustering
## =====================
##
# cluster_partition_handling = ignore

## pause_if_all_down strategy require additional configuration
# cluster_partition_handling = pause_if_all_down

## Recover strategy. Can be either 'autoheal' or 'ignore'
# cluster_partition_handling.pause_if_all_down.recover = ignore

## Node names to check
# cluster_partition_handling.pause_if_all_down.nodes.1 = rabbit@localhost
# cluster_partition_handling.pause_if_all_down.nodes.2 = hare@localhost

## Mirror sync batch size, in messages. Increasing this will speed
## up syncing but total batch size in bytes must not exceed 2 GiB.
## Available in RabbitMQ 3.6.0 or later.
##
# mirroring_sync_batch_size = 4096

## Make clustering happen *automatically* at startup. Only applied
## to nodes that have just been reset or started for the first time.
##
## Relevant doc guide: http://rabbitmq.com//cluster-formation.html
##

# cluster_formation.peer_discovery_backend     = rabbit_peer_discovery_classic_config
#
# cluster_formation.classic_config.nodes.1 = rabbit1@hostname
# cluster_formation.classic_config.nodes.2 = rabbit2@hostname
# cluster_formation.classic_config.nodes.3 = rabbit3@hostname
# cluster_formation.classic_config.nodes.4 = rabbit4@hostname

## DNS-based peer discovery. This backend will list A records
## of the configured hostname and perform reverse lookups for
## the addresses returned.

# cluster_formation.peer_discovery_backend = rabbit_peer_discovery_dns
# cluster_formation.dns.hostname = discovery.eng.example.local

## This node's type can be configured. If you are not sure
## what node type to use, always use 'disc'.
# cluster_formation.node_type = disc

## Interval (in milliseconds) at which we send keepalive messages
## to other cluster members. Note that this is not the same thing
## as net_ticktime; missed keepalive messages will not cause nodes
## to be considered down.
##
# cluster_keepalive_interval = 10000

##
## Statistics Collection
## =====================
##

## Set (internal) statistics collection granularity.
##
## Can be none, coarse or fine
# collect_statistics = none

# collect_statistics = coarse

## Statistics collection interval (in milliseconds). Increasing
## this will reduce the load on management database.
##
# collect_statistics_interval = 5000

##
## Misc/Advanced Options
## =====================
##
## NB: Change these only if you understand what you are doing!
##

## Explicitly enable/disable hipe compilation.
##
# hipe_compile = false

## Timeout used when waiting for Mnesia tables in a cluster to
## become available.
##
# mnesia_table_loading_retry_timeout = 30000

## Retries when waiting for Mnesia tables in the cluster startup. Note that
## this setting is not applied to Mnesia upgrades or node deletions.
##
# mnesia_table_loading_retry_limit = 10

## Size in bytes below which to embed messages in the queue index.
## Related doc guide: http://rabbitmq.com/persistence-conf.html
##
# queue_index_embed_msgs_below = 4096

## You can also set this size in memory units
##
# queue_index_embed_msgs_below = 4kb

## Whether or not to enable background periodic forced GC runs for all
## Erlang processes on the node in "waiting" state.
##
## Disabling background GC may reduce latency for client operations,
## keeping it enabled may reduce median RAM usage by the binary heap
## (see https://www.erlang-solutions.com/blog/erlang-garbage-collector.html).
## 
## Before trying this option, please take a look at the memory
## breakdown (http://www.rabbitmq.com/memory-use.html).
##
# background_gc_enabled = false

## Target (desired) interval (in milliseconds) at which we run background GC.
## The actual interval will vary depending on how long it takes to execute
## the operation (can be higher than this interval). Values less than
## 30000 milliseconds are not recommended.
##
# background_gc_target_interval = 60000

## Whether or not to enable proxy protocol support.
## Once enabled, clients cannot directly connect to the broker
## anymore. They must connect through a load balancer that sends the
## proxy protocol header to the broker at connection time.
## This setting applies only to AMQP clients, other protocols
## like MQTT or STOMP have their own setting to enable proxy protocol.
## See the plugins documentation for more information.
##
# proxy_protocol = false

## Log direcrory, taken from the RABBITMQ_LOG_BASE env variable by default.
##
# log.dir = /var/log/rabbitmq

## Logging to file. Can be false or a filename.
## Default:
# log.file = rabbit.log

## To disable logging to a file
# log.file = false

## Log level for file logging
##
# log.file.level = info

## File rotation config. No rotation by default.
## DO NOT SET rotation date to ''. Leave the value unset if "" is the desired value
# log.file.rotation.date = $D0
# log.file.rotation.size = 0

## Logging to console (can be true or false)
##
# log.console = false

## Log level for console logging
##
# log.console.level = info

## Logging to the amq.rabbitmq.log exchange (can be true or false)

## RabbitMQ LDAP Plugin
##
## Related doc guide: http://rabbitmq.com/ldap.html.
##
## ----------------------------------------------------------------------------

# =======================================
# LDAP section
# =======================================

##
## Connecting to the LDAP server(s)
## ================================
##

## Specify servers to bind to. You *must* set this in order for the plugin
## to work properly.
##
# auth_ldap.servers.1 = your-server-name-goes-here

## You can define multiple servers
# auth_ldap.servers.2 = your-other-server

## Connect to the LDAP server using TLS
##
# auth_ldap.use_ssl = false

## Specify the LDAP port to connect to
##
# auth_ldap.port = 389

## LDAP connection timeout, in milliseconds or 'infinity'
##
# auth_ldap.timeout = infinity

## Or number
# auth_ldap.timeout = 500

## Enable logging of LDAP queries.
## One of
##   - false (no logging is performed)
##   - true (verbose logging of the logic used by the plugin)
##   - network (as true, but additionally logs LDAP network traffic)
##
## Defaults to false.
##
# auth_ldap.log = false

## Also can be true or network
# auth_ldap.log = true
# auth_ldap.log = network

##
## Authentication
## ==============
##

## Pattern to convert the username given through AMQP to a DN before
## binding
##
# auth_ldap.user_dn_pattern = cn=${username},ou=People,dc=example,dc=com

## Alternatively, you can convert a username to a Distinguished
## Name via an LDAP lookup after binding. See the documentation for
## full details.

## When converting a username to a dn via a lookup, set these to
## the name of the attribute that represents the user name, and the
## base DN for the lookup query.
##
# auth_ldap.dn_lookup_attribute = userPrincipalName
# auth_ldap.dn_lookup_base      = DC=gopivotal,DC=com

## Controls how to bind for authorisation queries and also to
## retrieve the details of users logging in without presenting a
## password (e.g., SASL EXTERNAL).
## One of
##  - as_user (to bind as the authenticated user - requires a password)
##  - anon    (to bind anonymously)
##  - {UserDN, Password} (to bind with a specified user name and password)
##
## Defaults to 'as_user'.
##
# auth_ldap.other_bind = as_user

## Or can be more complex:
# auth_ldap.other_bind.user_dn  = User
# auth_ldap.other_bind.password = Password

## If user_dn and password defined - other options is ignored.

# -----------------------------
# Too complex section of LDAP
# -----------------------------

##
## Authorisation
## =============
##

## The LDAP plugin can perform a variety of queries against your
## LDAP server to determine questions of authorisation.
##
## Related doc guide: http://rabbitmq.com/ldap.html#authorisation.

## Following configuration should be defined in additional.config file
## DO NOT UNCOMMENT THIS LINES!

## Set the query to use when determining vhost access
##
## {vhost_access_query, {in_group,
##                       "ou=${vhost}-users,ou=vhosts,dc=example,dc=com"}},

## Set the query to use when determining resource (e.g., queue) access
##
## {resource_access_query, {constant, true}},

## Set queries to determine which tags a user has
##
## {tag_queries, []}
#   ]},
# -----------------------------

　　　　rabbitmq-defaults文件内容如下：

　　　　

　　　　b、RABBITMQ_HOME是环境变量的位置，由上看出配置文件是/data/soft/rabbitmq_server-3.7.9/etc/rabbitmq/rabbitmq.conf（注意是rabbitmq.conf，不是rabbitmq，不知道为啥rabbitmq-defaults是rabbitmq），将模版改名为rabbitmq.conf，放入/data/soft/rabbitmq_server-3.7.9/etc/rabbitmq/下

　　　　c、在配置文件rabbitmq.conf中，增加内容或去掉注，改成为

loopback_users.guest = false

　　9、修改配置文件后重新启动RabbitMQ服务，浏览器输入http://ip:15672，进入web控制台。
