ubuntu 添加开机自动运行脚本

1.编写shell脚本
gedit /etc/init.d/mongo-server
#!/bin/bash
/usr/local/mongodb/bin/mongod --logpath /var/log/mongodb/mongodb.log --logappend --fork --dbpath /var/db/mongodb --pidfilepath /var/run/mongod.pid
2. chmod 755 /etc/init.d/mongo-server   
3. ubuntu默认启动级别为2加载的脚本在/etc/rc2.d/
ln -s /etc/init.d/mongo-server /etc/rc2.d/S99mongo-server (S为开始执行99为执行顺序mongo-server为文件名)
