CentOS 5.5使用yum来安装LAMP并安装phpMyAdmin

使用yum来安装LAMP

1. 换源。 

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，而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 
一样，完成后，用/etc/init.d/mysqld start 启动mysql 

2.2.2 设置mysql密码  

mysqladmin -u root password "密码"

2.2.3 容许远程登陆 
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 

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 

4.1在/var/www/html/新建个test.php文件，将如下内容写入，而后保存。 
<? 
phpinfo(); 
?> 
4.2 防火墙配置 
a.添加.容许访问端口{21: ftp, 80: http}.

修改防火墙配置文件： 
vi /etc/sysconfig/iptables 
增长下面两行： 
-A RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 21 -j ACCEPT  

-A RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT

b.关闭防火墙. 
service iptables stop 
c.重置加载防火墙 
service iptables restart 
4.3而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。

安装phpMyAdmin

具体参看：http://faq.comsenz.com/viewnews-484

这里几个地方须要注意：

1.  phpMyAdmin包下载过来解压以后， libraries 目录下的config.default.php配置文件，修改过以后，须要复制到上一级目录，并改名为config.inc.php。一开始就是一直改 config.default.php，发现无效，后来才发现真正起效果的是config.inc.php这个文件，因此配置应该在这个文件里面改。

2.修改完配置文件以后，讲整个 phpMyAdmin文件夹上传到 web能够访问的目录下，好比/var/www/html/ 文件夹下～
