mongoDB脚本安装

1.编写安装脚本

vim mongodb.sh

#!/bin/bash
# Check if user is root
if [ $(id -u) != "0" ]; then
    echo "Error: You must be root to run this script, please use root to optimization system"
    exit 1
fi
echo "Select Install
    1 YUM MongoDB 3.6
    2 YUM MongoDB 4.0
    3 Tar MongoDB 3.6
    4 Tar MongoDB 4.0
    5 don't install is now
"
sleep 0.1
read -p "Please Input 1,2,3,4,5: " SERVER_ID
if [[ $SERVER_ID == 3 ]]; then
    SERVER="tar3"
elif [[ $SERVER_ID == 1 ]]; then
    SERVER="yum1"
elif [[ $SERVER_ID == 2 ]]; then
    SERVER="yum2"
elif [[ $SERVER_ID == 4 ]]; then
    SERVER="tar4"
else
    exit
fi

2.安装mongodb

sh mongodb.sh

3.配置用户

[root@localhost ~]# mongodb/mongo.sh start 
[root@localhost ~]# mongodb/bin/mongo 
> use admin; 
> db.createRole({role:'sysadmin',roles:[],privileges:[{resource:{anyResource:true},actions:['anyAction']}]}); 
> db.createUser({user:'admin',pwd:'Admin@123',roles:[{role:'sysadmin',db:'admin'}]}); 
> use history; 
switched to db history 
> db.createUser({user:'history',pwd:'history',roles:[{role:'readWrite',db:'history'}]});

4.添加认证启动

[root@localhost ~]# mongodb/mongo.sh stop

修改启动脚本mongo.sh 在启动命令中添加--auth变成如下

numactl --interleave=all $CMD --auth -f $CONF
[root@localhost ~]# mongodb/mongo.sh start

5.锁库

db.fsyncLock();
db.fsyncUnlock()

6.导出备份

mongodump --port 27019 -d dspt -u admin -p admin -o /home/long/mongodb/bak --authenticationDatabase admin

7.导入备份

mongorestore --port 27019 -d dspt -u admin -p admin /home/long/mongodb/bak/dspt/ --authenticationDatabase admin

8.测试

mongo 127.0.0.1:27019 
>use admin; 
> db.auth("admin","Admin@123") 
> show dbs 
> show collections 
> db.history_1745.drop()  #删除history_1745表名

附：

无mongo.conf，用命令启动

mongodb mongod --fork --dbpath=mongodb/data/db/ --logpath=mongodb/log/mongodb.log --logappend

--fork 后台运行

--logappend 防止日志被删除

--rest  28017  web用户界面

如脚本执行报错，请使用vim -b 编辑脚本，发现脚本中有^M，请使用以下方法修改

sed -i ‘s/^M//g' filename

注意：^M的输入方式是 Ctrl + v ，然后Ctrl + M，使用键盘上的shift+6打出的^是没用的
