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 acpid stop service atd stop service auditd stop service avahi-daemon stop service avahi-dnsconfd stop service bluetooth stop service conman stop service cpuspeed stop service cups stop service dnsmasq stop service dund stop service firstboot stop service hidd stop service httpd stop service ibmasm stop service ip6tables stop service iptables stop service irda stop service kdump stop service lm_sensors stop service mcstrans stop service messagebus stop service microcode_ctl stop service netconsole stop service netfs stop service netplugd stop service nfs stop service nfslock stop service nscd stop service ntpd stop service oddjobd stop service pand stop service pcscd stop service portmap stop service psacct stop service rdisc stop service restorecond stop service rpcgssd stop service rpcidmapd stop service rpcsvcgssd stop service saslauthd stop service setroubleshoot stop service smb stop service vncserver stop service winbind stop service wpa_supplicant stop service xfs stop service ypbind stop service yum-updatesd stop chkconfig acpid off chkconfig atd off chkconfig auditd off chkconfig avahi-daemon off chkconfig avahi-dnsconfd off chkconfig bluetooth off chkconfig conman off chkconfig cpuspeed off chkconfig cups off chkconfig dnsmasq off chkconfig dund off chkconfig firstboot off chkconfig hidd off chkconfig httpd off chkconfig ibmasm off chkconfig ip6tables off chkconfig iptables off chkconfig irda off chkconfig kdump off chkconfig lm_sensors off chkconfig mcstrans off chkconfig messagebus off chkconfig microcode_ctl off chkconfig netconsole off chkconfig netfs off chkconfig netplugd off chkconfig nfs off chkconfig nfslock off chkconfig nscd off chkconfig ntpd off chkconfig oddjobd off chkconfig pand off chkconfig pcscd off chkconfig portmap off chkconfig psacct off chkconfig rdisc off chkconfig restorecond off chkconfig rpcgssd off chkconfig rpcidmapd off chkconfig rpcsvcgssd off chkconfig saslauthd off chkconfig setroubleshoot off chkconfig smb off chkconfig vncserver off chkconfig winbind off chkconfig wpa_supplicant off chkconfig xfs off chkconfig ypbind off chkconfig yum-updatesd off 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 (责任编辑：IT) |
