CentOS 5.5使用yum来安装LAMP(php运行环境)

作者： 字体：[增加 减小] 类型：转载

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. 

# 

# 

[base] 

name=CentOS-$releasever - Base 

baseurl=http://mirrors.sohu.com/centos/$releasever/os/$basearch/ 

gpgcheck=1 

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

#released updates 

[updates] 

name=CentOS-$releasever - Updates 

baseurl=http://mirrors.sohu.com/centos/$releasever/updates/$basearch/ 

gpgcheck=1 

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

#packages used/produced in the build but not released 

[addons] 

name=CentOS-$releasever - Addons 

baseurl=http://mirrors.sohu.com/centos/$releasever/addons/$basearch/ 

gpgcheck=1 

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

#additional packages that may be useful 

[extras] 

name=CentOS-$releasever - Extras 

baseurl=http://mirrors.sohu.com/centos/$releasever/extras/$basearch/ 

gpgcheck=1 

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

#additional packages that extend functionality of existing packages 

[centosplus] 

name=CentOS-$releasever - Plus 

baseurl=http://mirrors.sohu.com/centos/$releasever/centosplus/$basearch/ 

gpgcheck=1 

enabled=0 

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>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，将以下内容写入，然后保存。 

<? 

phpinfo(); 

?> 

4.2 防火墙配置 

a.添加.允许访问端口{21: ftp, 80: http}. 

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}. 

service iptables stop 

c.重置加载防火墙 

service iptables restart 

4.3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。
