标签:files -- getconf 基础配置 gre auth sum firewall service
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
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
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
注意:配置的ip数与选择的模板相关联
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
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
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
shell脚本文件目前放置在mongodb的安装目录下:
?config.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。
?template 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

模板需要配置的几项内容:
如有需要,可自行配置6、7或者更多的机器分配mongo模板
①autoCheckLive.sh脚本为创建所在服务器对应的mongodb的进程存活监控,不存在则自动拉起。
#! /bin/bash #shell目录的绝对路径 shellPath=$1 configPath=$shellPath/config.properties #从config.properties文件读取数据出来 clusterPath=`awk -F= -v k=clusterPath ‘{ if ( $1 == k ) print $2; }‘ $configPath` template=`awk -F= -v k=template ‘{ if ( $1 == k ) print $2; }‘ $configPath` templatePath=$shellPath/template/$template.conf ips=`awk -F= -v k=ips ‘{ if ( $1 == k ) print $2; }‘ $configPath` #ip数组 eval $(echo $ips | awk ‘{split($0, arr, ","); for(i in arr) print "ipArray["i"]="arr[i]}‘) #本地ip localIp=`/sbin/ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6 | awk ‘{print $2}‘ | tr -d "addr:"` suffix="" #判断linux系统cpu是否为numa架构,如果是则传回_numa,禁用numactl numaCount=`grep -i numa /var/log/dmesg | wc -l` nodeCount=`grep -i numa /var/log/dmesg | grep -wi "node" | wc -l` offCount=`grep -i numa /var/log/dmesg | grep -wi "numa=off" | wc -l` if [[ ($numaCount -gt 1) && ($nodeCount -gt 1) && ($offCount -eq 0) ]] then suffix="_numa" fi #遍历ip数组 for((i=1; i<=${#ipArray[@]}; i++)) do #获取本地ip在模板中的代称号,根据本地ip所在ip数组中的下标数字获取 if [[ $localIp = ${ipArray[i]} ]] then #获取模板中本地ip对应的代称号所拥有的mongo节点 mongodbNodes=`awk -F= -v k=node$i ‘{ if ( $1 == k ) print $2; }‘ $templatePath` eval $(echo $mongodbNodes | awk ‘{split($0, mongodbArr, ","); for(y in mongodbArr) print "mongodbArray["y"]="mongodbArr[y]}‘) for n in ${mongodbArray[*]} do pid=`cat $clusterPath/$n/pid/$n.pid` #判断是否存活 count=`ps -ef | grep $pid | grep -v grep | wc -l` #程序挂掉啦,启动 if [ $count -eq 0 ];then cd $shellPath && $shellPath/autoStartUp.sh $n$suffix fi done fi done
②autoClusterClose.sh脚本为mongodb集群关闭脚本,用法:./autoClusterClose.sh shutdown或者./autoClusterClose.sh kill,这里建议使用shutdown方式关闭。

③autoClusterIndex.sh脚本为mongodb集群初始化配置文件和修改系统配置、config和shard副本集以及mongos路由启动并初始化、mongodb集群数据库表分片和基础数据初始化的脚本、添加定时任务。用法:./ autoClusterIndex.sh。使用该脚本,可以全自动化安装mongodb。
#! /bin/bash configPath=config.properties #从config.properties文件读取数据出来 clusterPath=`awk -F= -v k=clusterPath ‘{ if ( $1 == k ) print $2; }‘ $configPath` mongodb_home=`awk -F= -v k=mongodbHome ‘{ if ( $1 == k ) print $2; }‘ $configPath` ips=`awk -F= -v k=ips ‘{ if ( $1 == k ) print $2; }‘ $configPath` localIp=`/sbin/ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6 | awk ‘{print $2}‘ | tr -d "addr:"` user=`awk -F= -v k=user ‘{ if ( $1 == k ) print $2; }‘ $configPath` template=`awk -F= -v k=template ‘{ if ( $1 == k ) print $2; }‘ $configPath` templatePath=template/$template.conf #获取所有的配置、路由、分片 nodes=`awk -F= -v k=nodes ‘{ if ( $1 == k ) print $2; }‘ $templatePath` eval $(echo $nodes | awk ‘{split($0, nodeArr, ","); for(i in nodeArr) print "nodeArray["i"]="nodeArr[i]}‘) eval $(echo $ips | awk ‘{split($0, arr, ","); for(i in arr) print "ipArray["i"]="arr[i]}‘) #遍历ip数组 for((i=1; i<=${#ipArray[@]}; i++)) do if [[ $localIp = ${ipArray[i]} ]] then #1.创建mongodbCluster并修改系统配置 echo "********************************start ${ipArray[i]} autoConfig && autoSystemProperties********************************" $mongodb_home/shell/autoConfig.sh && $mongodb_home/shell/autoSystemProperties.sh else #把远程服务器旧的mongodb安装包删除 ssh $user@${ipArray[i]} "rm -rf $mongodb_home" #把mongodb安装包拷贝到远程服务器 scp -r $mongodb_home $user@${ipArray[i]}:$mongodb_home echo "********************************start ${ipArray[i]} autoConfig && autoSystemProperties********************************" ssh $user@${ipArray[i]} "cd $mongodb_home/shell && $mongodb_home/shell/autoConfig.sh && $mongodb_home/shell/autoSystemProperties.sh" fi done #2.mongodb集群启动config、shard1、shard2、shard3 echo "********************************start mongodb集群启动config、shard1、shard2、shard3********************************" #不启动mongos,只启动config,shards $mongodb_home/shell/autoClusterStartUp.sh notmongos #3.mongodb集群配置、分片的副本集初始化 echo "********************************start mongodb集群分片和副本集初始化********************************" $mongodb_home/shell/autoClusterInitSvr.sh cs #4.mongodb集群启动mongos echo "********************************start mongodb集群mongos********************************" mongoss=`awk -F= -v k=mongos ‘{ if ( $1 == k ) print $2; }‘ $templatePath` eval $(echo $mongoss | awk ‘{split($0, mongosArr, ","); for(i in mongosArr) print "mongosArray["i"]="mongosArr[i]}‘) for mongosNode in ${mongosArray[*]} do #删除node,保留右边字符 mongosIpNum=${mongosNode#*node} mongosIp=${ipArray[$mongosIpNum]} if [[ $localIp = $mongosIp ]] then echo "****************start $mongosIp mongos****************" $mongodb_home/shell/autoStartUp.sh mongos else echo "****************start $mongosIp mongos****************" ssh $user@$mongosIp "cd $mongodb_home/shell && ./autoStartUp.sh mongos" fi done #5.mongodb集群mongos初始化 echo "********************************start mongodb集群mongos初始化********************************" $mongodb_home/shell/autoClusterInitSvr.sh mongos #6.mongodb集群数据库表分片和初始化 echo "********************************start mongodb集群数据库表分片和初始化********************************" $mongodb_home/shell/autoClusterShardedAndInitDB.sh #7.mongodb集群配置定时任务:日志每天切割,保留7天日志/每隔10分钟监控mongo进程是否存活,不存活则自动拉起 for((i=1; i<=${#ipArray[@]}; i++)) do if [[ $localIp = ${ipArray[i]} ]] then echo "******************************** ${ipArray[i]} 添加定时任务:日志切割和mongo存活监控 ********************************" $mongodb_home/shell/autoConfig.sh addCronTask else echo "******************************** ${ipArray[i]} 添加定时任务:日志切割和mongo存活监控 ********************************" ssh $user@${ipArray[i]} "cd $mongodb_home/shell && $mongodb_home/shell/autoConfig.sh addCronTask" fi done
④autoClusterInitSvr.sh脚本为mongodb集群config、shard和mongos初始化脚本。用法:./autoClusterInitSvr.sh cs,初始化config和shard副本集配置;./autoClusterInitSvr.sh mongos,初始化mongos路由配置。

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")

?initConfig.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。
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。
