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 -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，修改系统设置
添加用户：
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@yq-mapp-otadb248 etc]# id mongodb id: mongodb: No such user [root@yq-mapp-otadb248 etc]# [root@yq-mapp-otadb248 etc]# [root@yq-mapp-otadb248 etc]# groupadd mongodb useradd -g mongodb mongodb[root@yq-mapp-otadb248 etc]# useradd -g mongodb mongodb [root@yq-mapp-otadb248 etc]# [root@yq-mapp-otadb248 etc]# [root@yq-mapp-otadb248 etc]# id mongodb uid=801(mongodb) gid=801(mongodb) groups=801(mongodb) [root@yq-mapp-otadb248 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@yq-mapp-otadb248 local]#
[root@yq-mapp-otadb248 local]# mkdir -p /data/mongo_27117/{db,log,tmp}
[root@yq-mapp-otadb248 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@yq-mapp-otadb248 local]#
[root@yq-mapp-otadb248 local]# ps -ef|grep mongo

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 -u admin -p admin --authenticationDatabase admin
该步骤，实际操作过程如下：
>

{
"_id" : "admin.useradmin",
"user" : "useradmin",
"db" : "admin",
"credentials" : {
"SCRAM-SHA-1" : {

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+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 /proc/32321/limits cat /etc/security/limits.d/90-nproc.conf vim /etc/security/limits.d/90-nproc.conf
该步骤实际操作过程如下：

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
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最后服务启动和停止mongodb实例的过程为：
[root@yq-mapp-otadb248 ~]# [root@yq-mapp-otadb248 ~]# service mongodb stop Stopping MongoDB port 27117 [root@yq-mapp-otadb248 ~]# [root@yq-mapp-otadb248 ~]# [root@yq-mapp-otadb248 ~]# [root@yq-mapp-otadb248 ~]# service mongodb start Starting MongoDB port 27117 ... [root@yq-mapp-otadb248 ~] about to fork child process, waiting until server is ready for connections. forked process: 36088 child process started successfully, parent exiting [root@yq-mapp-otadb248 ~]#以上所述是小编给大家介绍的mongodb 3.2.5安装过程详细记录，希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对网站的支持！
