编译安装php5.4.45

234123

1.PHP下载地址  http://www.php.net/releases/
2.HTTPD下载地址 http://mirrors.hust.edu.cn/apache/
由于webtatic不对php5.4版本提供支持服务，所以需要手动编译安装
https://webtatic.com/packages/php54/

这其中有两种情况：
1.yum 安装 httpd，编译安装php5.4.45
a. yum install httpd httpd-devel
b. tar zxvf php-5.4.45.tar.gz
cd php-5.4.45
注意：编译安装PHP前，必须确保原来yum安装的php5.3已经被移出，否则不会生成libphp5.so文件。
./configure --with-apxs2=/usr/sbin/apxs --with-mysql
make && make install
cp php.ini-development /usr/local/lib/php.ini
sed -i 's%;date.timezone =%date.timezone = Asia/Shanghai%' /usr/local/lib/php.ini
验证 /etc/httpd/conf/httpd.conf文件是否已经加载了libphp5.so模块
grep "libphp5.so" /etc/httpd/conf/httpd.conf
添加apache 解析php文件
sed '/ .gz .tgz/a\AddType application/x-httpd-php .php' /etc/httpd/conf/httpd.conf

2.编译安装 httpd2.2  php5.4.45
a. tar zxvf httpd-2.2.31.tar.gz
   cd httpd-2.2.31
   ls
   ./configure --enable-so
   make && make install
   /usr/local/apache2/bin/apachectl start
   lsof -i:80
   /usr/local/apache2/bin/apachectl stop
   lsof -i:80
b. cd ../
   cd php-5.4.45
   ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql
   make && make install
   cp php.ini-development /usr/local/lib/php.ini
c. sed -i 's%;date.timezone =%date.timezone = Asia/Shanghai%' /usr/local/lib/php.ini
验证 /usr/local/apache2/conf/httpd.conf文件是否已经加载了libphp5.so模块
grep "libphp5.so" /usr/local/apache2/conf/httpd.conf
添加apache 解析php文件
sed '/ .gz .tgz/a\AddType application/x-httpd-php .php' /usr/local/apache2/conf/httpd.conf

d. 验证
/usr/local/apache2/bin/apachectl start
echo "<?php phpinfo(); ?>" > index.php
查看是否能正常显示php的配置。
