Mongodb的安装部署配置
[*]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
# mkdir /tools
# cd /tools/
下载安装包
# wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.2.3.tgz
# 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
# mkdir /home/mongodb #创建MongoDB程序存放目录
# mkdir /data/mongodata-p #创建数据存放目录
# mkdir /data/log/mongolog-p #创建日志存放目录
安装
# tar -zxvf mongodb-linux-x86_64-rhel62-3.2.3.tgz
# 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
# echo 'exportPATH=$PATH:/home/mongodb/bin' >> /etc/profile
# 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
# ln -s /home/mongodb/bin/mongo/usr/bin/mongo
# ll /usr/bin/mongo
lrwxrwxrwx 1 root root 23 2月25 13:49 /usr/bin/mongo ->/home/mongodb/bin/mongo
