CentOS使用yum来安装LAMP

今天用yum方法搭建起了个LAMP环境,中间遇到了很多问题,经过google和各位前辈的帮助,终于将环境搭建起来,现在把完整的步骤记录下来,

1.  换源,sohu的相当好用。

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

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.
#
#

#additional packages that may be useful

gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5

1.3更新一下。

yum -y update

2.  用yum安装Apache,Mysql,PHP.

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&gt;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

3.  安装php

yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml

/etc/init.d/httpd start

4.  测试一下

在/var/www/html/新建个test.php文件,将以下内容写入,然后保存。

<?

phpinfo();

?>

然后在客户端浏览器里打开http://serverip/test.php,若能成功显示,则表示安装成功。        

至此,安装完毕。感慨,yum真是太好用了。
