开机启动管理
setup第四项(不重要)可以设置
3、chkconfig 命令主要用来更新(启动或停止)和查询系统服务的运行级信息。
chkconfig[--add][--del][--list][系统服务] 或 chkconfig [--level <等级代号>][系统服务][on/off/reset]
--level《等级号》指定读系统服务要在哪一个执行等级中开启或关闭
--list sshd 产看指定服务是否开机自启动
主要管理/etc/init.d/sshdstart 下的文件
原理实现:
!!!脚本开头必须包含chkconfig管理的代码
chkconfig :12345 13 98
description: oldboy test
1、把脚本放到/etc/init.d下面,并且可执行,希望被chkcofig管理,就用添加进去chkconfig --add sshd
2、添加进去的默认在哪个级别上启动看开发脚本中chkconfig的配置,服务启动顺序和关闭顺序也是看脚本中的chkconfig的配置
3、chkconfig --level 3 sshd on实质
rm -f /etc/rc.d/rc3.d/Knnsshd ln -s/etc/init.d/sshd /etc/rc.d/rc3.d/Snnsshd
4、关闭chkconfig --level 3 sshd off
rm -f /etc/rc.d/rc3.d/Snnsshd ln -s/etc/init.d/sshd /etc/rc.d/rc3.d/Knnsshd
[[email protected] ~]# chkconfig --list crond
crond 0:off 1:off 2:off 3:off 4:off 5:off 6:off
[[email protected] ~]# chkconfig --level 3crond on
[[email protected] ~]# chkconfig --list crond
crond 0:off 1:off 2:off 3:on 4:off 5:off 6:off

[[email protected] init.d]# vi oldboy
# chkconfig: 2345 91 61
echo "Welcome to oldboytraining:"
[[email protected] init.d]# cat oldboy
# chkconfig: 2345 91 61
echo "Welcome to oldboytraining:"
[[email protected] init.d]# chmod +x oldboy
[[email protected] init.d]# /etc/init.d/oldboystrt
Welcome to oldboy training:
[[email protected] init.d]# /etc/init.d/oldboy start
Welcome to oldboy training:
[[email protected] init.d]# chkconfig --addoldboy
[[email protected] init.d]# chkconfig --listoldboy
oldboy 0:off 1:off 2:on 3:on 4:on 5:on 6:off
--exclude=data/2排除 过滤data下的文件2其余都打包
[[email protected] ~]# tar zcvf/tmp/zhang.tar.gz data --exclude=4.txt
data/
data/7.txt
data/8.txt
1、尽量切换到打包目录的上一级目录,然后用相对路径打包,除非是你想保留完整路径

可以讲一段文本的某一段 切 出来,处理的信息是以行为单位
-f依据-d分隔符将一段信息切割成为数段,用-f取出第几段的意思
[[email protected] ~]# ifconfig eth0|sed -n ‘2p‘|cut -d ‘:‘ -f 2
10.0.0.128 Bcast
[[email protected] ~]# ifconfig eth0|sed -n ‘2p‘|cut -d ‘:‘ -f 2|cut -d ‘ ‘ -f 1
