CentOS 安装 PHP
1.获取PHP安装文件：downloads 或直接下载php-5.5.9.tar.gz
获取安装php需要的支持文件：libxml2 或直接下载libxml2-2.9.1.tar.gz
2.安装libxml2
tar zxvf libxml2-2.9.1.tar.gz cd libxml2-2.6.32 ./configure --prefix=/usr/local/libxml2 make make install
如果安装成功以后，在/usr/local/libxml2/目录下将生成bin、include、lib、man和share五个目录。在后面安装PHP5源代码包的配置时，会通过在configure命令的选项中加上"--with-libxml-dir=/usr/ local/libxml2"选项，用于指定安装libxml2库文件的位置。
3.安装php5
#cd php-5.3.8
#./configure \
--prefix=/usr/local/php \
--with-mysql=/usr/local/mysql \
--with-apxs=/usr/local/apache2/bin/apxs \
--with-libxml-dir=/usr/local/libxml2
#make
#make install
4.重新配置apache2让他支持php
- 配置 httpd.conf 让apache支持PHP：
# vi /usr/local/apache/conf/httpd.conf
找到 AddType application/x-gzip .gz .tgz 在其下添加如下内容
AddType application/x-httpd-php .php (.前面有空格)
AddType application/x-httpd-php-source .phps (.前面有空格)
- 然后CPOPY PHP的配置文件
cp php-5.3.8/php.ini.dist /usr/local/php/lib/php.ini
（如果没有php.ini.dist 则把php.ini-development php.ini-production中的任何一个重命名为php.ini.dist即可。）
修改php.ini文件 register_globals = On
- 重启apache
service apache restart
5.测试php是否成功安装
写一个php测试页info.php，放到apache2/htdocs中。
<?php
phpinfo();
?>;
在浏览器中输入：服务器地址/info.php
如果能正常显示出php的信息，则说明Apche+Mysql+PHP安装成功！
------------------------------
CentOS 5.5使用yum来安装LAMP
1. 换源，使用sohu安装源
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，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安装Apache、Mysql、PHP
2.1 安装Apache
yum install httpd httpd-devel
安装完成后，启动apache
/etc/init.d/httpd start
设为开机启动:chkconfig httpd on
2.2 安装mysql
yum install mysql mysql-server mysql-devel
完成后，启动mysql
/etc/init.d/mysqld start
2.2.2 设置mysql密码
mysql -uroot
mysql> USE mysql;
mysql>UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';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 'username'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION; FLUSH PRIVILEGES;
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。
<?php
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。
PHP 升级
1.先查看当前php版本
#php -v
2.升级php版本
rpm --import http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy
wget -P /etc/yum.repos.d/ http://repo.webtatic.com/yum/webtatic.repo
yum --enablerepo=webtatic update php mysql
升级php最好是连mysql一起升级,好了可以看到php已经升级成5.3.28
3、查看升级后的php版本
#php -v
PHP 5.3.28 (cli) (built: Dec 15 2013 17:43:05)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2013 Zend Technologies
可以看到php的版本已经更新到5.3.X
重启/etc/init.d/httpd restart 或apache service httpd restart
----------------------
升级 2（推荐）
1） 预安装
yum --enablerepo=remi,remi-php55 install php-pecl-apc php-cli php-pear php-pdo php-mysqlnd php-pgsql php-pecl-mongo php-sqlite php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml2） 升级php
yum --enablerepo=remi,remi-php55 install php-opcacheUnable to load dynamic library '/usr/lib64/php/modules/gd.so
[root@ithomer ~]# php -v
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/gd.so' - libvpx.so.0: cannot map zero-fill pages: Cannot allocate memory in Unknown on line 0

解决：
-----------------------------------------------------------
Error: Package: php-common-5.3.28-2.w5.x86_64 (webtatic)
Requires: libcurl.so.3()(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
yum install libcurl libcurl-devel
----------------------------
MySQL 升级
CentOS 5.5的源mysql目前还停留在5.0.19上，要做数据库主从的时候，必须升级到5.1以上，索性直接到5.5.36
1、安装MySQL 5.5.x的yum源：
rpm -Uvhhttp://repo.webtatic.com/yum/centos/5/latest.rpm
2、安装MySQL客户端的支持包：
yum install libmysqlclient15 --enablerepo=webtatic
3、卸载MySQL老版本的软件包：
yum remove mysql mysql-*
4、安装MySQL 5.5的客户端和服务端：
yum install mysql55 mysql55-server --enablerepo=webtatic
5、启动MySQL系统服务，更新数据库：
/etc/init.d/mysqld restart
mysql_upgrade -uroot -proot
升级完毕
/etc/init.d/mysqld restart
------------------------------------------------------------
