本文介绍下,在centos 5.5系统中使用yum安装lamp环境的方法,有需要的朋友参考下。

分享下centos 5.5系统中yum方式安装lamp环境的步骤。
 
1. 首先,更换yum源,sohu的相当好用。
1.1备份CentOS-Base.repo
 

复制代码 代码示例:
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.
#
#

1.3更新一下。
 

复制代码 代码示例:
yum -y update

2. 用yum安装apache,mysql,PHP.

2.1安装Apache
 

复制代码 代码示例:
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:

复制代码 代码示例:
chkconfig httpd on

2.2 安装mysql
2.2.1

复制代码 代码示例:
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
 

复制代码 代码示例:
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
 

复制代码 代码示例:
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
 

复制代码 代码示例:
chkconfig mysqld on

3. 安装php
 

复制代码 代码示例:
yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml
/etc/init.d/httpd start

4. 测试安装结果
4.1在/var/www/html/新建个test.php文件,将以下内容写入,然后保存。
 

复制代码 代码示例:
<?
phpinfo();
?>

4.2 iptables防火墙配置
a.添加.允许访问端口{21: ftp, 80: http}.
 

复制代码 代码示例:
iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 21 -j ACCEPT
iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT

b.关闭防火墙{不推荐}.
 

复制代码 代码示例:
service iptables stop
 

c.重置加载防火墙
service iptables restart

4.3 在客户端浏览器中打开http://serverip/test.php,若能成功显示,则表示安装成功。
