小试牛刀  chkconfig设置自定义服务随机启动

[root@xencms2 ~]# chkconfig --add convirtd  #将服务加入chkconfig管理
[root@xencms2 ~]# chkconfig --list convirtd    
convirtd        0:off   1:off   2:on    3:on    4:on    5:on    6:off
 
确认脚本启动、关闭是否符合要求：
1、查看chkconfig管理服务启动级别
[root@xencms2 ~]# ll  /etc/rc3.d/S66convirtd 
lrwxrwxrwx 1 root root 18 May 21 12:33 /etc/rc3.d/S66convirtd -> ../init.d/convirtd
[root@xencms2 ~]# ll /etc/rc1.d/K66convirtd 
lrwxrwxrwx 1 root root 18 May 21 12:33 /etc/rc1.d/K66convirtd -> ../init.d/convirtd
2、脚本关闭服务功能
[root@xencms2 convirt]# ps aux|grep convirt |grep -v grep
root     15590 12.3  0.4 714472 56312 ?        Sl   13:57   0:02 /root/convirt/tg2env/bin/python /root/convirt/tg2env/bin/paster serve ./src/convirt/web/convirt/development.ini --daemon --pid-file ./paster.pid
#已经有进程，说明服务是启动状态
[root@xencms2 convirt]# /etc/init.d/convirtd stop       #测试关闭功能
Shutting down Convirt daemon
[root@xencms2 convirt]# ps aux|grep convirt |grep -v grep #查看已经无进程
3、脚本查看服务状态功能
[root@xencms2 convirt]# /etc/init.d/convirtd status     
convirt-ctl is stopped
4、脚本启动服务功能
[root@xencms2 convirt]# /etc/init.d/convirtd start             
Starting Convirt daemon
[root@xencms2 convirt]# ps aux|grep convirt |grep -v gre
root     15764 46.2  0.4 778332 54364 ?        Sl   13:58   0:02 /root/convirt/tg2env/bin/python /root/convirt/tg2env/bin/paster serve ./src/convirt/web/convirt/development.ini --daemon --pid-file ./paster.pid
[root@xencms2 convirt]# /etc/init.d/convirtd status     
convirt-ctl (pid  15764) is running...
