         *  创建用户 admin，test，admin1
 *  说明

# 下载 #

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86\_64-3.6.12.tgz

# 具体 #

### 解压安装 ###

[root@localhost ~]# cd /usr/local
    [root@localhost local]# tar -zxvf mongodb-linux-x86_64-3.6.12.tgz
    // 移动到mongodb
    [root@localhost local]# mkdir mongodb
    [root@localhost local]# mv mongodb-linux-x86_64-3.6.12 mongodb
    // 新建数据、日志、配置目录
    mkdir -p /data/mongodb/data
    mkdir -p /data/mongodb/logs
    mkdir -p /data/mongodb/etc
    touch /data/mongodb/logs/mongo.log
    vim /data/mongodb/etc/mongo.conf

mongodb.conf的内容如下（bind\_ip改为自己服务器的地址）

dbpath=/data/mongodb/data 
    logpath=/data/mongodb/logs/mongo.log 
    fork=true 
    logappend=true 
    journal=true 
    quiet=true 
    bind_ip=0.0.0.0 
    port=27017

修改profile

vim /etc/profile
    # 内容添加到文件后面
    export MONGODB_HOME=/usr/local/mongodb/mongodb-linux-x86_64-3.6.12 
    export PATH=$PATH:$MONGODB_HOME/bin

### 设置开机启动 ###

// 新建并编辑
    vim /etc/init.d/mongod
    
    # 内容如下
    #!/bin/bash 
    # chkconfig: - 85 15 
    name=mongod 
    path_bin=/usr/local/mongodb/mongodb-linux-x86_64-3.6.12/bin/ 
    path=/data/mongodb/ 
    case "$1" in 
    	start) 
    		${path_bin}${name} --dbpath=${path}data --logpath=${path}logs/mongo.log --logappend --fork --bind_ip=0.0.0.0 
    		if [ $? -eq 0 ];then 
    			echo "${name}启动成功..." 
    		else
    			echo "${name}启动失败..." 
    		fi 
    	;;
    	stop) 
    		if [ $(ps -ef|grep "mongod" |grep "fork"|awk {'print $2'}) -gt 0 ];then 
    			kill `ps -ef|grep "mongod" |grep "fork"|awk {'print $2'}` 
    			if [ $? -eq 0 ];then 
    				echo "${name}停止成功" 
    			else
    				echo "${name}停止失败" 
    			fi 
    		else
    			echo "${name}进程已经停止" 
    		fi 
    	;;
    	restart) 
    		if [ $(ps -ef|grep "mongod" |grep "fork"|awk {'print $2'}) -gt 0 ];then 
    			kill `ps -ef|grep "mongod" |grep "fork"|awk {'print $2'}` 
    			if [ $? -eq 0 ];then 
    				echo "${name}停止成功" 
    			else
    				echo "${name}停止失败" 
    			fi 
    		else
    			echo "${name}进程已经停止" 
    		fi
    		echo "${name}启动中..." 
    		sleep 3s 
    		${path_bin}${name} --dbpath=${path}data --logpath=${path}logs/mongo.log --logappend --fork --bind_ip=0.0.0.0 
    		if [ $? -eq 0 ];then 
    			echo "${name}重启成功" 
    		else
    			echo "${name}重启失败" 
    		fi 
    	;;	
    	*)
    		echo "${name}start|stop|restart" 
    	;; 
    esac

加入开机自动启动

cd /etc/init.d/
    chmod a+x mongod
    // 加入系统服务
    chkconfig --add mongod
    // 开机服务自启
    chkconfig mongod on

### 验证开机启动 ###

#重启系统生效 
    shutdown -r now 
    
    #查看 mongodb 是否已启动 
    [root@localhost ~]# ps aux | grep mongod 
    root       6955  0.0  0.0 112724   992 pts/0    S+   22:11   0:00 grep --color=auto mongod
    
    #开启 
    service mongod start 
    #停止 
    service mongod stop 
    #重启 
    service mongod restart

### 创建用户 admin，test，admin1 ###

[root@localhost ~]# cd /usr/local/mongodb/mongodb-linux-x86_64-3.6.12/bin/
    [root@localhost bin]# mongodb
    > use admin
    > db.system.users.find().pretty()
    
    > db.createUser({user:'admin',pwd:'123456',roles:['root']}); 
    > db.auth("admin","123456");
    
    > db.createUser({user:'test',pwd:'123456',roles:[{role:'dbOwner', db:'test'}]});
    
    > db.createUser({user:'admin1',pwd:'123456',roles:[{role:'userAdminAnyDatabase', db:'admin'}]});
    // 查看用户
    > db.system.users.find().pretty()
    {

    		}
    	]
    }

#开启 mongodb 服务
    [root@localhost bin]# service mongod stop
    [root@localhost bin]# mongod --auth --dbpath /data/mongodb/data --bind_ip 192.168.230.128 &
    # 关闭
    [root@localhost bin]# mongod --shutdown --dbpath /data/mongodb/data --bind_ip 192.168.230.128
    # 查看
    [root@localhost ~]# ps aux | grep mongod

# 说明 #

*  3.5 版本之后，配置文件中须指明 bind\_ip，否则默认为 127.0.0.1，且启动时也要加上 --bind\_ip 参数，**但貌似没用**

[root@localhost ~]# service mongod start --bind_ip=192.168.230.128
    about to fork child process, waiting until server is ready for connections.
    forked process: 7104
    child process started successfully, parent exiting
    mongod启动成功...
    [root@localhost ~]# 
    [root@localhost ~]# ps aux | grep mongod

*  若之前是低版本（如 3.0.2），使用 3.6.12 版本时，需修改项目中 mongodb 相关配置 文件。
 *  用户权限 新建的库（如 NEW\_CACHE）,需要创建用户和授权，否则在连接时因匹配不到用户而报 错。如创建 test01 用户，授予读写权限，命令如下：

mongo 
    use NEW_CACHE
    db.createUser({user:'test01',pwd:'test01',roles:[{role:'readWrite', db:'NEW_CACHE'}]});
