生产上安装mongodb全过程

mongodb-linux-x86_64-4.0.2.tgz
生产上安装mongodb
操作系统为 centos6.5

第一步 执行优化脚本 初始化脚本

第二步：上传mongodb的二进制安装包

[root@prd3-mongodb-10-182 opt]# lltotal 69368-rw-r--r--  1 root root 71023715 Aug 28  2018 mongodb-linux-x86_64-4.0.2.tgzdrwxr-xr-x. 2 root root     4096 Nov 22  2013 rhdrwxr-xr-x  2 root root     4096 Apr 25  2019 scripts[root@prd3-mongodb-10-182 opt]# tar zxvf mongodb-linux-x86_64-4.0.2.tgz -C /usr/local/[root@prd3-mongodb-10-182 local]# mv mongodb-linux-x86_64-4.0.2/ mongodb

第三步验证是否安装成功[root@prd3-mongodb-10-182 local]# /usr/local/mongodb/bin/mongod --versiondb version v4.0.2git version: fc1573ba18aee42f97a3bb13b67af7d837826b47allocator: tcmallocmodules: nonebuild environment:    distarch: x86_64    target_arch: x86_64

第五步设置变量环境[root@prd3-mongodb-10-182 local]# echo 'export PATH=/usr/local/mongodb/bin:$PATH' >> /etc/profile[root@prd3-mongodb-10-182 local]# source /etc/profile

第六步 创建相关的目录[root@prd3-mongodb-10-182 local]# mkdir /ivargo[root@prd3-mongodb-10-182 local]# cd /ivargo/[root@prd3-mongodb-10-182 ivargo]# mkdir app data log [root@prd3-mongodb-10-182 ivargo]# lltotal 12drwxr-xr-x 2 root root 4096 Apr 25 15:31 appdrwxr-xr-x 2 root root 4096 Apr 25 15:31 datadrwxr-xr-x 2 root root 4096 Apr 25 15:31 log[root@prd3-mongodb-10-182 ivargo]# mkdir -p /ivargo/app/mongodb/conf[root@prd3-mongodb-10-182 data]# pwd/ivargo/data[root@prd3-mongodb-10-182 data]# mkdir mdb 

第七步 上传配置文件[root@prd3-mongodb-10-182 conf]# pwd/ivargo/app/mongodb/conf[root@prd3-mongodb-10-182 conf]# lltotal 4-rw-r--r-- 1 root root 853 Nov 15 16:36 mongo.conf

第八步：启动mongodb[root@prd3-mongodb-10-182 conf]# mongod -f /ivargo/app/mongodb/conf/mongo.conf about to fork child process, waiting until server is ready for connections.forked process: 1741child process started successfully, parent exiting[root@prd3-mongodb-10-182 conf]# netstat -lntupActive Internet connections (only servers)Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name   tcp        0      0 0.0.0.0:22                  0.0.0.0:*                   LISTEN      1515/sshd           tcp        0      0 127.0.0.1:25                0.0.0.0:*                   LISTEN      1591/master         tcp        0      0 0.0.0.0:27017               0.0.0.0:*                   LISTEN      1741/mongod         tcp        0      0 :::22                       :::*                        LISTEN      1515/sshd           tcp        0      0 ::1:25                      :::*                        LISTEN      1591/master  [root@prd3-mongodb-10-182 conf]# ps -ef|grep mongoroot       1741      1  1 15:38 ?        00:00:01 mongod -f /ivargo/app/mongodb/conf/mongo.confroot       1788   1767  0 15:39 pts/1    00:00:00 tailf /ivargo/log/mongod.logroot       1792   1661  0 15:40 pts/0    00:00:00 grep --color=auto mongo

第九步：查看日志进行验证优化[root@prd3-mongodb-10-182 ~]# tailf /ivargo/log/mongod.log   2019-04-25T15:38:47.238+0800 I CONTROL  [initandlisten] ** WARNING: soft rlimits too low. rlimits set to 14735 processes, 65535 files.

温柔的关闭mongodb[root@prd3-mongodb-10-182 conf]# mongo 127.0.0.1:27017   //先进入MongoDB shell version v4.0.2connecting to: mongodb://127.0.0.1:27017/testMongoDB server version: 4.0.2Welcome to the MongoDB shell.For interactive help, type "help".For more comprehensive documentation, see        http://docs.mongodb.org/Questions?
