mongodb 3.2.5安装详细过程
1.准备安装介质
安装介质下载：
mongodb的安装方式，我通常使用二进制包的方式，内网不能配置连接外网的yum源；
官方建议的mongodb下载地址为：Downloads.mongodb.org
但实际上，这个地址，很难找到下载表，正常下载，通常可以用下面的下载地址选择下载：
https://www.mongodb.org/dl/linux/x86_64
我这里下载的是：3.2.5版本对应的mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8.tgz
如果将整个mongodb安装过程已经编写了脚本，可以获取安装脚本，用脚本执行安装；
如果手动安装，则可跳过此步；
手工安装mongodb的脚步的执行过程，一般如下：
mkdir-p/root/{software,scripts}
wget-qhttp://ptmaster.test.cn/files/init/mongodb_install.sh-O/root/scripts/mongodb_install.sh
cd/root/scripts
./mongodb_install.sh-p27117
2.添加mongodb用户和环境变量，修改系统设置
添加用户：
groupaddmongodb useradd-gmongodbmongodb
创建mongodb脚本目录
mkdir-p/home/mongodb/scripts/
修改目录权限：
chown-Rmongodb:mongodb/home/mongodb/scripts/
在/etc/profile中添加mongodb用户的环境变量：
#MongoDBEnvironmentVariables exportPATH=$PATH:$HOME/bin:/usr/local/mongodb/bin:/home/mongodb/scripts/
是上面的变量生效：
source/etc/profile
实际操作过程如下：
[root@yq-mapp-otadb248etc]#idmongodb id:mongodb:Nosuchuser [root@yq-mapp-otadb248etc]# [root@yq-mapp-otadb248etc]# [root@yq-mapp-otadb248etc]#groupaddmongodb useradd-gmongodbmongodb[root@yq-mapp-otadb248etc]#useradd-gmongodbmongodb [root@yq-mapp-otadb248etc]# [root@yq-mapp-otadb248etc]# [root@yq-mapp-otadb248etc]#idmongodb uid=801(mongodb)gid=801(mongodb)groups=801(mongodb) [root@yq-mapp-otadb248etc]#
mongodb要求hugepage设置为禁用，softlimit设置足够大，可以在一开始修改，也可以到后面修改；
cat/etc/security/limits.d/90-nproc.conf
修改这个文件中下列的值
*softnproc2048
确保：softnproc的值至少是softnofile值的一半；
修改后，退出当前用户，重新进入一下，设置就可以生效了；
禁用hugepage的值：
#echo"never">/sys/kernel/mm/transparent_hugepage/enabled #echo"never">/sys/kernel/mm/transparent_hugepage/defrag
备注：上面两个警告，现在不修改也不影响安装过程，后面会提示。
3.安装mongodb软件
上传并解压软件：
cd/usr/local rzmongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8.tgz tar-zxvfmongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8.tgz ln-svmongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8/usr/local/mongodb
修改文件权限：
chown-Rmongodb:mongodbmongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8 chown-Rmongodb:mongodb/usr/local/mongodb
实际操作过程如下：

4.创建mongodb实例所需的目录和配置文件
创建mongodb实例所需目录：
mkdir-p/data/mongo_27117/{db,log,tmp}
创建mongodb实例配置文件所需目录和文件：
mkdir-p/etc/mongodb touch/etc/mongodb/mongo_27117.conf
根据需要配置mongodb的启动参数，我的启动参数配置内容如下：
vim/etc/mongodb/mongo_27117.conf
dbpath=/data/mongo_27117/db logpath=/data/mongo_27117/log/mongo_27117.log pidfilepath=/data/mongo_27117/tmp/mongo_27117.pid storageEngine=wiredTiger wiredTigerCacheSizeGB=2 syncdelay=30 wiredTigerCollectionBlockCompressor=zlib port=27117 auth=true directoryperdb=true oplogSize=2048 logappend=true fork=true #rest=true journal=true journalCommitInterval=50 slowms=200
修改目录、文件的权限和属组：
chown-Rmongodb:mongodb/data/mongo_27117/ chown-Rmongodb:mongodb/etc/mongodb
确认目录和配置文件都已经准备完毕：
ls-l/data/mongo_27117/ ls-l/etc/mongodb cat/etc/mongodb/mongo_27117.conf
该步骤实际操作过程如下：
[root@yq-mapp-otadb248local]#
[root@yq-mapp-otadb248local]#mkdir-p/data/mongo_27117/{db,log,tmp}
[root@yq-mapp-otadb248local]#mkdir-p/etc/mongodb

5.启动mongodb实例，修改管理员密码
使用下面的命令启动mongodb服务：
/usr/local/mongodb/bin/mongod--config/etc/mongodb/mongo_27117.conf
确认密码，mongodb的管理员密码，可以根据各自的规则设置：
echo$MONGODB_ROOT_PASS mongodb_020248_Pass
修改管理员密码，注意mongodb3.2要对admin授予三个角色，这点与之前的版本不同：
/usr/local/mongodb/bin/mongo--port=27117
db.createUser({user:'useradmin',pwd:'mongodb_020248_Pass',roles:[{"role":"clusterAdmin","db":"admin"},{"role":"userAdminAnyDatabase","db":"admin"},{"role":"dbAdminAnyDatabase","db":"admin"}]})
db.auth("useradmin","mongodb_020248_Pass")
db.system.users.find();
生成密码后,使用新用户和密码登陆mongo,确认状态：
/usr/local/mongodb/bin/mongo--port=27117-uuseradmin-pmongodb_020248_Pass--authenticationDatabaseadmin
该步骤操作过程如下；

6.为应用创建业务账号
创建一个admin/admin用户，具有可以自行创建用户和数据库的权限，密码业务自己再修改：
db.createUser({user:'admin',pwd:'admin',roles:[{role:'userAdminAnyDatabase',db:'admin'},{role:'dbAdminAnyDatabase',db:'admin'}]})
验证业务账号登陆：
/usr/local/mongodb/bin/mongo--port=27117-uadmin-padmin--authenticationDatabaseadmin
该步骤，实际操作过程如下：
>

7.实例启动时的报警处理
在mongodb启动过程中，有时会提示一些警告，其中常见的两类警告处理过程如下：
警告1：
提示：
2016-10-19T12:12:59.097+0800ICONTROL[initandlisten]**WARNING:softrlimitstoolow.rlimitssetto2048processes,8192files.Numberofprocessesshouldbeatleast4096:0.5timesnumberoffiles.
处理方式，根据提示，将processes值，由现在的2048，修改为4096，甚至更高的值。
ps-ef|grepmongod cat/proc/32321/limits cat/etc/security/limits.d/90-nproc.conf vim/etc/security/limits.d/90-nproc.conf

处理：
echo"never">/sys/kernel/mm/transparent_hugepage/enabled echo"never">/sys/kernel/mm/transparent_hugepage/defrag
该步骤，实际操作过程如下：
[root@yq-mapp-otadb248limits.d]#cat/sys/kernel/mm/transparent_hugepage/enabled [always]madvisenever [root@yq-mapp-otadb248limits.d]#cat/sys/kernel/mm/transparent_hugepage/defrag [always]madvisenever [root@yq-mapp-otadb248limits.d]# [root@yq-mapp-otadb248limits.d]#echo"never">/sys/kernel/mm/transparent_hugepage/enabled [root@yq-mapp-otadb248limits.d]#echo"never">/sys/kernel/mm/transparent_hugepage/defrag [root@yq-mapp-otadb248limits.d]# [root@yq-mapp-otadb248limits.d]#cat/sys/kernel/mm/transparent_hugepage/enabled alwaysmadvise[never] [root@yq-mapp-otadb248limits.d]#cat/sys/kernel/mm/transparent_hugepage/defrag alwaysmadvise[never] [root@yq-mapp-otadb248limits.d]# [root@yq-mapp-otadb248limits.d]#
8.创建mongodb实例服务管理脚本
为了方便对mongodb实例的启动和停止，可以先创建mongodb的启动脚本，停止脚本，然后在/etc/init.d/目录下创建一个服务脚本，这样就可以用service进行实例管理了。
脚本1：启动脚本：
vim/home/mongodb/scripts/mongodb_start.sh
#!/bin/sh #thescriptsisusedtostartmongodbinstancewithport27117. #createdbyzhaofxon20161019. echo-n"StartingMongoDBport27117..." /usr/local/mongodb/bin/mongod--config/etc/mongodb/mongo_27117.conf&
脚本二：停止脚本：
vim/home/mongodb/scripts/mongodb_stop.sh
#!/bin/bash
#thescriptsisusedtostopmongodbinstancewithport27117.
#createdbyzhaofxon20161019.
echo-n"StoppingMongoDBport27117"
pid=`ps-opid,commandax|grepmongod|awk'!/awk/&&!/grep/{print$1}'`;
if["${pid}"!=""];then
kill-2${pid};
fi
脚本三：服务脚本：
vim/etc/init.d/mongodb
vim/etc/init.d/mongodb
#!/bin/sh
#thescriptsisusedtomangemongodbservicewithlinuxservicetype.
#createdbyzhaofxon20161019.
PATH=/usr/local/mongodb/bin:/sbin:/bin:/usr/sbin:/usr/bin
NAME=mongodb
start(){
/home/mongodb/scripts/mongodb_start.sh
}
stop(){
/home/mongodb/scripts/mongodb_stop.sh
}
test-x$DAEMON||exit0
set-e
case"$1"in
start)
start
;;
stop)
stop
;;
*)
N=/etc/init.d/$NAME
echo"Usage:$N{start|stop}">&2
exit1
;;
esac
exit0
修改脚本的属组，添加执行权限：
chown-Rmongodb:mongodb/home/mongodb/scripts/ chownmongodb:mongodb/etc/init.d/mongodb chmod+x/home/mongodb/scripts/mongodb_start.sh chmod+x/home/mongodb/scripts/mongodb_stop.sh chmod+x/etc/init.d/mongodb
最后服务启动和停止mongodb实例的过程为：
[root@yq-mapp-otadb248~]# [root@yq-mapp-otadb248~]#servicemongodbstop StoppingMongoDBport27117 [root@yq-mapp-otadb248~]# [root@yq-mapp-otadb248~]# [root@yq-mapp-otadb248~]# [root@yq-mapp-otadb248~]#servicemongodbstart StartingMongoDBport27117...[root@yq-mapp-otadb248~] abouttoforkchildprocess,waitinguntilserverisreadyforconnections. forkedprocess:36088 childprocessstartedsuccessfully,parentexiting [root@yq-mapp-otadb248~]#
