​通过chkconfig设置linux开机自启动服务

首先查看当前开启的服务有哪些：

默认只需要开通下面5个必要服务即可：

sshd |sysstat|crond|network|rsyslog

首先查看当前自启动的服务有哪些。由于工作环境基本上使用文本模式3级别，只需要查找3级别上开启的服务即可。

命令如下：

[[email protected] ~]# LANG=en (先调整成英文字符集，以方便过滤字符串)

[[email protected] ~]# chkconfig --list |grep 3:on （查看3级别下所有自启动的服务）

udev-post 0:off 1:on 2:on 3:on 4:on 5:on 6:off

处理思路：

1.先关闭所有服务，再开启需要保留的（默认只需要开通5个必要服务即可。）

操作过程：

[[email protected] ~]# chkconfig --list |grep 3:on |awk '{print "chkconfig",$1,"off"}' |bash

（关闭所有自启动的服务）

[[email protected] ~]# chkconfig --list （查看是否所有的自服务是否都关闭了）

svnserve 0:off 1:off 2:off 3:off 4:off 5:off 6:off

sysstat 0:off 1:on 2:off 3:off 4:off 5:off 6:off

udev-post 0:off 1:on 2:off 3:off 4:off 5:off 6:off

然后再执行一条命令去开启需要自启动的5个服务：

[[email protected] ~]# chkconfig --list |grep 3:off|egrep "sshd|sysstat|crond|network|rsyslog" |awk '{print "chkconfig",$1,"on"}'|bash （关闭所有自服务之后开启需要自启动的5个服务）

[[email protected] ~]# chkconfig --list |grep 3:on （查询设置情况并看是否只保留了我们需要的5个自启动服务）

crond 0:off 1:off 2:on 3:on 4:on 5:on 6:off

network 0:off 1:off 2:on 3:on 4:on 5:on 6:off

rsyslog 0:off 1:off 2:on 3:on 4:on 5:on 6:off

sshd 0:off 1:off 2:on 3:on 4:on 5:on 6:off

sysstat 0:off 1:on 2:on 3:on 4:on 5:on 6:off

2. 关掉不需要的，因为我们需要的服务默认都是开启的。

操作过程：

[[email protected] ~]# chkconfig --list |grep 3:on|egrep -v "sshd|sysstat|crond|network|rsyslog"|awk '{print "chkconfig",$1,"off"}'|bash

（一条命令排除我们需要保留的5个自启动服务并关闭其他服务）

[[email protected] ~]# chkconfig --list |grep 3:on （查询设置情况并看是否只保留了我们需要的5个自启动服务）

crond 0:off 1:off 2:on 3:on 4:on 5:on 6:off

network 0:off 1:off 2:on 3:on 4:on 5:on 6:off

rsyslog 0:off 1:off 2:on 3:on 4:on 5:on 6:off

sshd 0:off 1:off 2:off 3:on 4:off 5:off 6:off

sysstat 0:off 1:on 2:on 3:on 4:on 5:on 6:off

相对来说第2个方法更简单一点。大家可以根据需要灵活使用。

设置自启动服务也可以通过setup和ntsysv来处理。
