MongoDB3.6 一键化自动部署方案

1.系统基础配置

下面的命令默认都使用root用户进行操作,操作系统为Centos7,mongodb3.6.x以上版本

1.1 修改系统配置文件/etc/security/limits.conf和/etc/profile

 修改/etc/security/limits.conf持久化设置允许用户/进程打开文件句柄数,这一步需要重启系统,不然不起作用

* soft nofile 1048576

* hard nofile 1048576

* soft nproc 524288

* hard nproc 524288

修改/etc/profile,在最后添加ulimit -s 1024,然后保存并source /etc/profile

1.2 关闭每台机器的防火墙

Centos7以下命令:

chkconfig iptables off && service iptables stop

 

使用命令查看chkconfig --list 是否设置自动启动为关闭

Centos7以上命令:

systemctl stop firewalld

systemctl is-enabled firewalld  

1.3 每台机器修改/etc/hosts和hostname

在/etc/hosts添加集群所有的ip及对应的hostname

注意:配置的ip数与选择的模板相关联

1.4 机器之间配置ssh免密登录

每台机器分别执行下面命令,这里以5台机器为准:

ssh-keygen -t rsa -P "" -f /root/.ssh/id_rsa

ssh-copy-id node1

ssh-copy-id node2

ssh-copy-id node3

ssh-copy-id node4

ssh-copy-id node5

1.5 检测自动化部署所需的命令是否可用

ifconfig、ssh需要可用

需要安装numactl,使用rpm -qa | grep numactl查看numactl是否已安装

注意:完成上面5步操作后重启每台机器。重启完毕,使用命令ulimit -a 查看

要保证 open files 对应的值为 1048576

Stack size 对应的值为1024

Max user processes对应的值为 524288

1.6 检查mongodb安装下bin目录和shell目录执行权限

进入到shell目录,执行chmod +x auto*加执行权限

进入mongodb的bin目录,执行chmod +x ./*加执行权限

2.MongoDB 一键化部署

2.1 一键化部署shell文件介绍

shell脚本文件目前放置在mongodb的安装目录下:

⑪config.properties,配置文件,包括mongodb安装目录、mongoCluster集群安装目录、所需主机、数据库等等。如图:

 

上图几个参数可能需要随环境不同而修改。

说明:

ips=192.168.187.201, 192.168.187.202, 192.168.187.203, 192.168.187.204, 192.168.187.205

这里默认192.168.187.201为mongdb集群的节点node1,192.168.187.202为mongdb集群的节点node2,192.168.187.203为mongdb集群的节点node3,192.168.187.204为mongdb集群的节点node4,,192.168.187.205为mongdb集群的节点node5。

template与ips的ip数量对应,ips的ip数为5,则意味着采用5台机器的模板,这里默认为5。

⑬template 目录包括3.conf、4.conf和5.conf,为mongodb3台机器、4台机器和5台机器安装模板,有需要者可以自行修改模板。

3.conf 3台机器分配的mongodb节点模板为

#所有mongo节点
nodes=config,shard1,shard2,shard3,mongos
#机器分配到的mongo节点
node1=mongos,config,shard1,shard2,shard3
node2=mongos,config,shard1,shard2,shard3
node3=mongos,config,shard1,shard2,shard3
#mongo节点分配到的机器,注意shard部分排在第一的为master,第二为secondary,第三位arbitery
config=node1,node2,node3
mongos=node1,node2,node3
shard1=node1,node2,node3
shard2=node2,node3,node1
shard3=node3,node2,node1
#mongo节点端口
config_port=29040
mongos_port=29050
shard1_port=29010
shard2_port=29020
shard3_port=29030

注意:这里的node1、node2、node3不是机器hostname(当然也可以以这种node1、node2方式去命名hostname),只是机器ip的代名称,因为不同开发环境中的ip总是不同的,所以使用node1、node2...去代替变化的ip。这里的node1、node2、node3默认与config.properties中的ips属性对应,即ips中的第一个ip默认为node1,第二个ip默认为node2,第三个ip默认为node3,4.conf和5.conf类同。查看下图,可以清晰看到mongodb分布的节点:

4.conf 4台机器分配mongodb节点的模版为

#所有mongo节点
nodes=config,shard1,shard2,shard3,shard4,mongos
#机器分配到的mongo节点
node1=mongos,shard1,shard3,shard4
node2=mongos,config,shard1,shard2,shard4
node3=mongos,config,shard1,shard2,shard3
node4=config,shard2,shard3,shard4
#mongo节点分配到的机器,注意shard部分排在第一的为master,第二为secondary,第三位arbitery
config=node2,node3,node4
mongos=node1,node2,node3
shard1=node1,node2,node3
shard2=node2,node3,node4
shard3=node3,node4,node1
shard4=node4,node1,node2
#mongo节点端口
config_port=29040
mongos_port=29050
shard1_port=29000
shard2_port=29010
shard3_port=29020
shard4_port=29030

5.conf 5台机器分配mongodb节点的模版为

#所有mongo节点
nodes=config,shard1,shard2,shard3,shard4,shard5,mongos
#机器分配到的mongo节点
node1=mongos,shard1,shard4,shard5
node2=mongos,shard1,shard2,shard5
node3=config,shard1,shard2,shard3
node4=config,shard2,shard3,shard4
node5=config,shard3,shard4,shard5
#mongo节点分配到的机器, 注意shard部分排在第一的为master,第二为secondary,第三位arbitery
config=node3,node4,node5
mongos=node1,node2
shard1=node1,node2,node3
shard2=node2,node3,node4
shard3=node3,node4,node5
shard4=node4,node5,node1
shard5=node5,node1,node2
#mongo节点端口
config_port=29040
mongos_port=29050
shard1_port=29060
shard2_port=29070
shard3_port=29080
shard4_port=29090
shard5_port=29100

模板需要配置的几项内容:

  • mongodb所有节点
  • 每台机器分配的mongodb节点
  • 每个mongodb节点分配的机器
  • mongo节点的端口

如有需要,可自行配置6、7或者更多的机器分配mongo模板

上述代码实现的config、shards以及mongos配置内容如下:

config副本集配置,参考示例:

> config = {

...      _id : "configs",

...      members : [

...         {_id : 0, host : "192.168.187.203:29040"},

...         {_id : 1, host : "192.168.187.204:29040"},

...         {_id : 2, host : "192.168.187.205:29040"}

...      ]

... }

> rs.initiate(config)

shards副本集配置,参考示例:

> config = {

...      _id : "shard1",

...      members : [

...         {_id : 0, host : "192.168.187.201:29060",priority:2},

...         {_id : 1, host : "192.168.187.202:29060",priority:1},

...         {_id : 2, host : "192.168.187.203:29060", arbiterOnly : true}

...      ]

... }

> rs.initiate(config)

这里默认,第一个ip的优先级为2,第二个ip的优先级为1,第三个ip为仲裁节点,所以第一个ip为primary主节点,第二位secondary从节点,第三个只参与投票,shard1根据分片的数据变化为shard2、shard3、shard4、shard5等等。

mongos配置内容为添加shards,参考示例为:

sh.addShard("shard1/192.168.187.201:29060,192.168.187.202:29060,192.168.187.203:29060")

sh.addShard("shard2/192.168.187.202:29070,192.168.187.203:29070,192.168.187.204:29070")

sh.addShard("shard3/192.168.187.203:29080,192.168.187.204:29080,192.168.187.205:29080")

sh.addShard("shard4/192.168.187.204:29090,192.168.187.205:29090,192.168.187.201:29090")

sh.addShard("shard5/192.168.187.205:29100,192.168.187.201:29100,192.168.187.202:29100")

sh.status() #参考分片的情况是否添加上

⑤autoClusterShardedAndInitDB.sh 脚本为指定数据库testDB1、testDB2、testDB3及其数据库表分片。

#! /bin/bash

         pid=`cat $clusterPath/${mongodbArray[n]}/pid/${mongodbArray[n]}.pid`
         logdir=$clusterPath/${mongodbArray[n]}/log
         #切割日志
         /bin/kill -SIGUSR1 $pid
         find $logdir/ -mtime +$days -delete
       done
  fi
done

⑨autoStartUp.sh脚本为启动该脚本所在服务器的config、shard、mongos节点,启动分正常启动和禁止numactl启动两种。

#! /bin/bash

configPath=config.properties
mongodb_home=`awk -F= -v k=mongodbHome '{ if ( $1 == k ) print $2; }' $configPath`
clusterPath=`awk -F= -v k=clusterPath '{ if ( $1 == k ) print $2; }' $configPath`
param=$1

#config
if [[ $param = "config" ]]
then
   $mongodb_home/bin/mongod -f $clusterPath/conf/config.conf
fi
if [[ $param = "config_numa" ]]
then
   numactl --interleave=all $mongodb_home/bin/mongod -f $clusterPath/conf/config.conf
fi

#shard1
paramLegth=`echo "$param" |wc -L`
if [[ ($param =~ "shard") && ($paramLegth -lt 11) && ($paramLegth -gt 5)]]
then
   $mongodb_home/bin/mongod -f $clusterPath/conf/$param.conf
fi
if [[ ($param =~ "shard") && $param =~ "numa" ]]
then
   shardName=${param%_*}
   numactl --interleave=all $mongodb_home/bin/mongod -f $clusterPath/conf/$shardName.conf
fi

#mongos
if [[ $param = "mongos" ]]
then
   $mongodb_home/bin/mongos -f $clusterPath/conf/mongos.conf
fi

⑩autoSystemProperties.sh 脚本为修改服务器的系统配置,TCP配置等。

#! /bin/bash

#系统全局允许分配的最大文件句柄数
sysctl -w fs.file-max=2097152
sysctl -w fs.nr_open=2097152
echo 2097152 > /proc/sys/fs/nr_open

#允许当前会话/进程打开文件句柄数
ulimit -n 1048576

#修改fs.file-max设置到 /etc/sysctl.conf 文件:
#fs.file-max = 1048576

#修改/etc/security/limits.conf 持久化设置允许用户/进程打开文件句柄数,手动添加
#* soft nofile 1048576
#* hard nofile 1048576
#* soft nproc 524288
#* hard nproc 524288

#并发连接backlog设置
sysctl -w net.core.somaxconn=32768
sysctl -w net.ipv4.tcp_max_syn_backlog=16384
sysctl -w net.core.netdev_max_backlog=16384
#可用知名端口范围:
sysctl -w net.ipv4.ip_local_port_range='80 65535'
#sysctl -w net.core.rmem_default=262144
sysctl -w net.core.wmem_default=262144
sysctl -w net.core.rmem_max=16777216
sysctl -w net.core.wmem_max=16777216
sysctl -w net.core.optmem_max=16777216
#TCP Socket 读写 Buffer 设置:
sysctl -w net.core.rmem_default=262144
sysctl -w net.core.wmem_default=262144
sysctl -w net.core.rmem_max=16777216
sysctl -w net.core.wmem_max=16777216
sysctl -w net.core.optmem_max=16777216
sysctl -w net.ipv4.tcp_rmem='1024 4096 16777216'
sysctl -w net.ipv4.tcp_wmem='1024 4096 16777216'

#修改系统内核参数:
echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
echo "never" >  /sys/kernel/mm/transparent_hugepage/defrag

#TCP 连接追踪设置:
sysctl -w net.nf_conntrack_max=1000000
sysctl -w net.netfilter.nf_conntrack_max=1000000
sysctl -w net.netfilter.nf_conntrack_tcp_timeout_time_wait=30

#修改stack size为1024,不启作用,只能手动source
#if [ `grep -c "ulimit -s 1024" /etc/profile` -eq '0' ];then
#  echo "ulimit -s 1024" >> /etc/profile
#  source /etc/profile
#fi

⑫initConfig.zip 为数据库test及其数据库表的初始化文件,有需要的可以自行配置。

2.2 全自动化部署

1. 把mongodb安装目录放置在5台机器中的任意一台上面即可,选定好安装的路径。

2.进入mongodb/shell目录。

根据实际环境需要修改config.properties文件的clusterPath、mongodbHome、ips、template、数据库5个属性

3.autoClusterIndex.sh脚本所在的目录执行如下命令,否则脚本会不起作用,执行命令:

./autoClusterIndex.sh

执行上面命令,会一键自动化部署。

至此,完成部署。

2.3 部署验证

5台机器的验证:

服务器node1(192.168.187.201):

 

服务器node2(192.168.187.202):

 

服务器node3(192.168.187.203):

 

服务器node4(192.168.187.204):

 

服务器node5(192.168.187.205):

 

4台机器的验证:

服务器node1(192.168.187.201):

 

服务器node2(192.168.187.202):

 

服务器node3(192.168.187.203):

 

服务器node4(192.168.187.204):

 

3台机器的验证:

服务器node1(192.168.187.201)、服务器node2(192.168.187.202)、服务器node3(192.168.187.203)都会启动如下服务:
