空闲的时间安装VHCS，这个是用来做虚拟主机管理的，和CPANEL相比，VHCS是开源的，阿建用得着。 根据VHCS的安装文档重写如下，以方便安装 1. 安装OS choose "server" option during install firewall: open ssh/http/https/ftp/smtp ports selinux: disable (warn still generates errors in VHCS) select minimum install 安装类型选“自定义” 手动分区(4G虚拟硬盘) / ext3 2000M swap 2*mem /var ext3 剩余空间(用户数据在此分区上) eth0 关闭DHCP,10.10.10.180/255.255.255.0 hostname: srv180.capno.com gateway: 10.10.10.1 dns: 202.106.0.20/202.106.196.115 Enable firewall,默认的四个服务全允许(SSH/HTTP,HTTPS/FTP/SMTP) SELinux: Disable 安装包选择：Minimal最小化安装(676M) 2. 基本配置 # useradd admin;passwd admin(以下操作凡未说明的都以root身份执行) 使用ssh客户端连接server # vi /etc/fstab LABEL=/var /var ext3 defaults,usrquota 1 2 # touch /var/aquota.user; chmod 600 /var/aquota.user; mount -o remount /var; quotacheck -avugm # server iptables stop; mv /etc/rc.d/rc3.d/S08iptables /etc/rc.d/rc3.d/K08iptables # vi /etc/grub.conf timeout=1 删除以下无用的软件包(iiimf-server,iiimf-csconv,iiimf-docs,iiimf-libs,xorg-x11-xfs并未安装) # yum remove apmd autofs bluez-utils cups irda-utils isdn4k-utils pcmcia-cs sendmail ypbind xinetd 上传需要的软件包VHCS至/home/admin/ 包含vhcs安装包，yum安装和升级包(节约yum升级时间)，编译好的包(节约编译时间，第一次需要按官方文档自行编译) # cd /home/admin/VHCS/;
