查询现在server上的是不是存在mongodb和版本 查询操作 rpm -qa |grep mongodb 卸载操作 rpm -e --nodeps mongodb-2.4.14-1.el6.x86_64 验证卸载是不是成功 rpm -qa |grep mongodb
安装mongodb 新建安装包目录 [iyunv@git ~]# mkdir /tools [iyunv@git ~]# cd /tools/ 下载安装包 [iyunv@git tools]# wget https://fastdl.mongodb.org/linux ... 64-rhel62-3.2.3.tgz [iyunv@git tools]# ll 总用量 64944 -rw-r--r-- 1 root root 66502003 2月 18 05:18 mongodb-linux-x86_64-rhel62-3.2.3.tgz 环境准备 [iyunv@git tools]# mkdir /home/mongodb #创建MongoDB程序存放目录 [iyunv@git tools]# mkdir /data/mongodata-p #创建数据存放目录 [iyunv@git tools]# mkdir /data/log/mongolog-p #创建日志存放目录 安装 [iyunv@git tools]# tar -zxvf mongodb-linux-x86_64-rhel62-3.2.3.tgz [iyunv@git tools]# cdmongodb-linux-x86_64-rhel62-3.2.3 [root@gitmongodb-linux-x86_64-rhel62-3.2.3]# cp -r ./* bin/ GNU-AGPL-3.0 MPL-2 README THIRD-PARTY-NOTICES [root@gitmongodb-linux-x86_64-rhel62-3.2.3]# cp -r ./* /home/mongodb/ [root@gitmongodb-linux-x86_64-rhel62-3.2.3]# 环境变量设置 [iyunv@git ~]# echo 'exportPATH=$PATH:/home/mongodb/bin' >> /etc/profile [iyunv@git ~]# source /etc/profile
## 如果是安装命令的话，现在就已经可以结束了，但全局生效还是需要重启###### 避免重启的方法,生成软连接文件 [iyunv@git ~]# ln -s /home/mongodb/bin/mongo/usr/bin/mongo [iyunv@git ~]# ll /usr/bin/mongo lrwxrwxrwx 1 root root 23 2月 25 13:49 /usr/bin/mongo ->/home/mongodb/bin/mongo
