CentOS下配置Redis数据库

使用yum安装redis

yum install redis

配置redis.conf文件

使用vim编辑/etc/redis.conf文件

vim /etc/redis.conf

修改IP地址绑定

原本是bind 127.0.0.1。这里将它改为bind 0.0.0.0，允许公网访问

################################## NETWORK #####################################

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all available network interfaces on the host machine.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bsind 127.0.0.1 ::1
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only on the
# IPv4 loopback interface address (this means Redis will only be able to
# accept client connections from the same host that it is running on).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT OUT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# bind 127.0.0.1
bind 0.0.0.0

设置redis访问密码

# IMPORTANT NOTE: starting with Redis 6 "requirepass" is just a compatibility
# layer on top of the new ACL system. The option effect will be just setting
# the password for the default user. Clients will still authenticate using
# AUTH <password> as usually, or more explicitly with AUTH default <password>
# if they follow the new protocol: both will work.
#
# requirepass foobared
requirepass [你的密码]

更改redis端口

将默认的port 6379改为port 6380或其他空闲的端口

# Accept connections on the specified port, default is 6379 (IANA #815344).
# If port 0 is specified Redis will not listen on a TCP socket.
# port 6379
port 6380

设置密码和改端口是为了确保redis数据库的安全性。

若不设密码以默认端口将Redis向公网开发，可能导致Redis被pnscan病毒挟持挖矿。

启动Redis服务

# 启动redis
service redis start
# 停止redis
service redis stop
# 查看redis运行状态
service redis status
# 查看redis进程
ps -ef | grep redis
