Centos净化系统到最小安装及语言设置

时间:2015-05-25 01:20 来源:linux.it.net.cn 作者:IT

现在各种廉价vps让人眼花缭乱,光淘宝上就有N多,但大多数都很山寨,就拿centos系统来说,竟然装的是桌面版,叫人无语~~~

那么到底如何选择呢?

本文重点讲一下如何净化桌面版centos,使其更适合做服务器,避免不必要的内存开销。

首先是服务器以命令行模式启动,放弃桌面启动

vim /etc/inittab

修改 id:5:initdefault:

改为 id:3:initdefault:

然后保存退出

还原语言模式

vim /etc/sysconfig/i18n
#将里面的内容设置成
LANG="en_US.UTF-8"
SYSFONT="latarcyrheb-sun16"

然后重启系统,重新登录

删除X11环境

rpm -e --allmatches --nodeps `rpm -qa|grep x11`
rpm -e --allmatches --nodeps `rpm -qa|grep X11`

注意上面命令不是复制了两次,而是后一个X11是大写的

停止不必要的服务

service atd stop
service auditd stop
service avahi-daemon stop
service avahi-dnsconfd stop

删除无用的包

yum remove -y Deployment_Guide-en-US finger cups-libs cups bluez-libs desktop-file-utils ppp rp-pppoe wireless-tools irda-utils nfs-utils nfs-utils-lib rdate fetchmail eject ksh mkbootdisk mtools syslinux tcsh startup-notification talk apmd rmt dump setserial portmap yp-tools ypbind apmd autofs bluez-utils cups irda-utils iiimf-server iiimf-libs iiimf-csconv iiimf-docs isdn4k-utils pcmcia-cs sendmail xorg-x11-xfs ypbind xinetd

停掉并且删除一些不需要的 xinetd 服务

/sbin/service xinetd stop;
/sbin/chkconfig xinetd off
rm -rf /etc/xinetd.d

禁止一些 /etc/init.d/ 下面不需要的服务，

for a in acpid anacron apmd atd autofs avahi-daemon bluetooth cpuspeed \
cups firstboot gpm haldaemon hidd ip6tables irqbalance isdn kdump \
kudzumcstrans messagebus microcode_ctl netfs nfs nfslock pcscd portmap \
readahead_early readahead_later rpcgssd rpcidmapd sendmail \
setroublesshoot smartd xfs xinetd yum-updatesd; \
do /sbin/chkconfig $a off; done

重启系统后，检查一下正在运行中的服务，看看是不是都是必须的。

netstat -an | grep LISTEN
