1.1备份CentOS-Base.repo cd /etc/yum.repos.d/
cp CentOS-Base.repo CentOS-Base.repo.bak
1.2替换源 (以sohu更新源为例子) 用vi打开CentOS-Base.repo,并将内容清空,然后将下面的内容复制进去,并保存。
# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

1.3更新一下 yum -y update
2. 用yum升级安装Apache,Mysql,PHP.
Centos默认已安装相应的环境,但是版本可能达不到相关的要求。 A.安装部分2.1安装Apache yum install httpd httpd-devel
安装完成后,用/etc/init.d/httpd start 启动apache
设为开机启动:chkconfig httpd on 2.2 安装mysql 2.2.1 yum install mysql mysql-server mysql-devel
同样,完成后,用/etc/init.d/mysqld start 启动mysql 2.2.2设置mysql密码
mysql>; USE mysql;
mysql>; UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';
mysql>; FLUSH PRIVILEGES; 2.2.3 允许远程登录
mysql -u root -p
Enter Password: <your new password>
mysql>GRANT ALL PRIVILEGES ON *.* TO '用户名'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION;
完成后就能用mysql-front远程管理mysql了。 2.2.4设为开机启动
chkconfig mysqld on
