下载mongodb3.2版本
[root@mongo-test ~]# wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.2.3.tgz
解压mongodb以及改名mongodb
[root@mongo-test ~]# tar fxz mongodb-linux-x86_64-rhel62-3.2.3.tgz [root@mongo-test ~]# ll mongodb-linux-x86_64-rhel62-3.2.3 total 100 drwxr-xr-x 2 root root 4096 Mar 5 15:10 bin -rw-r--r-- 1 root root 34520 Feb 18 03:42 GNU-AGPL-3.0 -rw-r--r-- 1 root root 16726 Feb 18 03:42 MPL-2 -rw-r--r-- 1 root root 1359 Feb 18 03:42 README -rw-r--r-- 1 root root 35910 Feb 18 03:42 THIRD-PARTY-NOTICES [root@mongo-test ~]# mv mongodb-linux-x86_64-rhel62-3.2.3 /usr/local/mongodb
mongodb环境变量配置
vim /etc/profile export PATH=$PATH:/usr/local/mongodb/bin
加载环境配置文件
[root@mongo-test ~]# source /ect/profile
创建mongodb数据目录
[root@mongo-test ~]# mkdir /data
[root@mongo-test ~]# mkdir /data/{logs,mongo-data,config}//logs存放日志目录，mongo-data存放数据，config存放配置文件
[root@mongo-test ~]# tree /data/
/data/
├── config
├── logs
└── mongo-data
3 directories, 0 filesmongod配置文件如下：
[root@mongo-test config]# cat mongod.conf systemLog: destination: file path: /data/logs/mongod.log logAppend: true processManagement: fork: true pidFilePath: "/data/mongo-data/mongod.pid" net: port: 27017 http: enabled: true storage: dbPath: "/data/mongo-data" engine: wiredTiger wiredTiger: engineConfig: cacheSizeGB: 1 directoryForIndexes: true collectionConfig: blockCompressor: zlib indexConfig: prefixCompression: true journal: enabled: true directoryPerDB: true security: authorization: disable
注：现在mongo3.x以后的版本配置文件都是yaml格式的，官方关于mongo配置文件相关选项说明，https://docs.mongodb.org/manual/reference/configuration-options/#configuration-file
启动mongodb以及查看mongod端口
[root@mongo-test config]# mongod -f mongod.conf about to fork child process, waiting until server is ready for connections. forked process: 17222 child process started successfully, parent exiting [root@mongo-test config]# netstat -ntpl|grep mongod tcp 0 0 0.0.0.0:28017 0.0.0.0:* LISTEN 17222/mongod tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 17222/mongod
登陆mongod实例，并创建zxl以及在test集合中插入数据查询等等。。。
[root@mongo-test config]# mongo --port 27017
