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：

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 -q http://ptmaster.test.cn/files/init/mongodb_install.sh -O /root/scripts/mongodb_install.sh

cd /root/scripts

./mongodb_install.sh -p 27117

2 添加mongodb用户和环境变量，修改系统参数

groupadd mongodb

useradd -g mongodb mongodb

创建mongodb脚本目录

mkdir -p /home/mongodb/scripts/

修改目录权限：

chown -R mongodb:mongodb /home/mongodb/scripts/

在 /etc/profile 中添加 mongodb 用户的环境变量：

# MongoDB Environment Variables

export PATH=$PATH:$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@linuxidc etc]# id mongodb
id: mongodb: No such user
[root@linuxidc etc]#
[root@linuxidc etc]#
[root@linuxidc etc]# groupadd mongodb
useradd -g mongodb mongodb[root@linuxidc etc]# useradd -g mongodb mongodb
[root@linuxidc etc]#
[root@linuxidc etc]#
[root@linuxidc etc]# id mongodb
uid=801(mongodb) gid=801(mongodb) groups=801(mongodb)
[root@linuxidc etc]#

mongodb要求hugepage设置为禁用，soft limit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

* soft nproc 2048

确保： soft nproc 的值至少是 soft nofile 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

rz mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8.tgz

tar -zxvf mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8.tgz

ln -sv mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8 /usr/local/mongodb

修改文件权限：

chown -R mongodb:mongodb mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8

chown -R mongodb: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 -R mongodb:mongodb /data/mongo_27117/

chown -R mongodb: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@linuxidc local]#
[root@linuxidc local]# mkdir -p /data/mongo_27117/{db,log,tmp}
[root@linuxidc local]# 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 mongodb 3.2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 -u useradmin -p mongodb_020248_Pass --authenticationDatabase admin

该步骤操作过程如下；

[root@linuxidc local]#

6. 创建应用所需的业务账号

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 -u admin -p admin --authenticationDatabase admin

该步骤，实际操作过程如下：

>
> db.system.users.find().pretty()
{
"_id" : "admin.useradmin",
"user" : "useradmin",
"db" : "admin",
"credentials" : {
"SCRAM-SHA-1" : {
"iterationCount" : 10000,
"salt" : "6hLx/d97hS+yfoN47QTmXQ==",

}
},

},

}
]
}

7. 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+0800 I CONTROL [initandlisten] ** WARNING: soft rlimits too low. rlimits set to 2048 processes, 8192 files. Number of processes should be at least 4096 : 0.5 times number of files.

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|grep mongod

cat /etc/security/limits.d/90-nproc.conf

vim /etc/security/limits.d/90-nproc.conf

2016-10-19T12:12:59.097+0800 I CONTROL [initandlisten]

2016-10-19T12:12:59.097+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.

2016-10-19T12:12:59.097+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never'

确认：

cat /sys/kernel/mm/transparent_hugepage/enabled

cat /sys/kernel/mm/transparent_hugepage/defrag

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@linuxidc limits.d]# cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
[root@linuxidc limits.d]# cat /sys/kernel/mm/transparent_hugepage/defrag
[always] madvise never
[root@linuxidc limits.d]#
[root@linuxidc limits.d]# echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
[root@linuxidc limits.d]# echo "never" > /sys/kernel/mm/transparent_hugepage/defrag
[root@linuxidc limits.d]#
[root@linuxidc limits.d]# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
[root@linuxidc limits.d]# cat /sys/kernel/mm/transparent_hugepage/defrag
always madvise [never]
[root@linuxidc limits.d]#
[root@linuxidc limits.d]#

8 创建mongodb实例管理脚本

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
# the scripts is used to start mongodb instance with port 27117.
# created by zhaofx on 20161019.
echo -n "Starting MongoDB port 27117 ... "
/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
# the scripts is used to stop mongodb instance with port 27117.
# created by zhaofx on 20161019.
echo -n "Stopping MongoDB port 27117"
pid=`ps -o pid,command ax | grep mongod | awk '!/awk/ && !/grep/ {print $1}'`;
if [ "${pid}" != "" ]; then
kill -2 ${pid};
fi

脚本三：服务脚本：

vim /etc/init.d/mongodb

#! /bin/sh
# the scripts is used to mange mongodb service with linux service type.
# created by zhaofx on 20161019.
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 || exit 0
set -e
case "$1" in
start)
start
;;
stop)
stop
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start|stop}" >&2
exit 1
;;
esac
exit 0

修改脚本的属组，添加执行权限：

chown -R mongodb:mongodb /home/mongodb/scripts/
chown mongodb: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

最后执行服务启动和停止mongodb实例的过程为：

[root@linuxidc ~]#
[root@linuxidc ~]# service mongodb stop
Stopping MongoDB port 27117
[root@linuxidc ~]#
[root@linuxidc ~]#
[root@linuxidc ~]#
[root@linuxidc ~]# service mongodb start
Starting MongoDB port 27117 ... [root@linuxidc ~]
about to fork child process, waiting until server is ready for connections.
forked process: 36088
child process started successfully, parent exiting
[root@linuxidc ~]#
