- 为了便于命令启动，需要编辑全局变量PATH
[root@snails ~]# vi /etc/profile.d/mongo.sh
export PATH=$PATH:/root/mongodb/bin
[root@snails ~]# source /etc/profile

创建服务文件
- 在mongodb/bin目录下创建配置文件mongodb.conf
[root@snails ~]# cd mongodb/bin
[root@snails bin]# vi mongodb.conf
#数据文件存放目录
dbpath = /data/mongodata
#日志文件存放目录
logpath = /data/log/mongolog/mongodb.log
#端口
port = 27017
#以守护程序的方式启用，即在后台运行
fork = true
nohttpinterface = true
启动服务
[root@snails bin]# mongod --dbpath=/data/mongodata --logpath=/data/log/mongolog/mongodb.log --logappend --fork
#通过配置文件启动
[root@snails bin]# mongod -f /root/mongodb/bin/mongodb.conf
netstat -tnlp | grep mongod
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 18093/mongod

消除警告
[root@snails bin]# vi /etc/rc.local

Tip:
如果发现加入到/etc/rc.local中的内容在重启后没有生效，检查下rc.local的权限及当前系统运行等级
[root@snails ~]# runlevel
[root@snails ~]# chmod +x /etc/rc.local
文件限制数调整
修改配置文件 /etc/security/limits.conf，添加配置信息：
* soft nofile 65535
* hard nofile 65535
* soft nproc 32000
* hard nproc 32000
停止mongodb
正常停止方法: kill -2 PID
