centos6.5怎么安装php5.5
1.******已安装Nginx******
ps -aux | grep nginx
netstat -anptu | grep 80
2.清除系统中php痕迹：
yum remove php
rm -rvf /etc/php
rm -rvf /etc/php.ini
rm -f /usr/bin/php
3.安装php所需软件包：
tar zxvf autoconf-2.68.tar.gz -C /usr/src
cd /usr/src/autoconf-2.68/
./configure make make install
tar zxvf libiconv-1.14.tar.gz -C /usr/src
cd /usr/src/libiconv-1.14/
./configure make make install
tar zxvf libmcrypt-2.5.8.tar.gz -C /usr/src
cd /usr/src/libmcrypt-2.5.8/
./configure make make install
ldconfig
cd libltdl/
./configure --enable-ltdl-install
make make install
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
tar zxvf mhash-0.9.9.9.tar.gz -C /usr/src
cd /usr/src/mhash-0.9.9.9/
./configure make make install
tar zxvf mcrypt-2.6.8.tar.gz -C /usr/src
cd /usr/src/mcrypt-2.6.8/
./configure make make install
4.加载php动态模块：
ln -s /usr/local/lib/libmcrypt.la /usr/lib64/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib64/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib64/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8
/usr/lib64/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib64/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib64/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib64/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib64/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1
/usr/lib64/libmhash.so.2.0.1
cp -R /usr/lib64/libpng.* /usr/lib/
cp -R /usr/lib64/libjpeg.* /usr/lib/
echo "/lib" /etc/ld.so.conf
echo "/usr/lib" /etc/ld.so.conf
echo "/usr/lib64" /etc/ld.so.conf
echo "/usr/local/lib" /etc/ld.so.conf
echo "* soft nproc 65535" /etc/security/limits.conf
echo "* hard nproc 65535" /etc/security/limits.conf
echo "* soft nofile 65535" /etc/security/limits.conf
echo "* hard nofile 65535" /etc/security/limits.conf
echo "fs.file-max=65535" /etc/sysctl.conf
ldconfig
5.解压、配置、编译、安装php：
tar zxvf php-5.5.25.tar.gz -C /usr/src
cd /usr/src/php-5.5.25/
./configure --prefix=/usr/local/php \

8.编辑php-fpm.conf配置文件：
cp /usr/local/php/etc/php-fpm.conf.default
/usr/local/php/etc/php-fpm.conf
vim /usr/local/php/etc/php-fpm.conf
[global]
pid = /home/php/pid/php-fpm.pid

pm.max_spare_servers = 6

9.编写php-fpm启动脚本
vim /etc/init.d/php-fpm
#!/bin/sh
# chkconfig:
2345 90
10
#
Description:
Start and
Stop php-fpm
# Provides:
php-fpm
#
Default-Start:
2 3 4 5
#
Default-Stop:
0 1 6
prefix=/usr/local/php
exec_prefix=${prefix}
php_fpm_BIN=${prefix}/sbin/php-fpm
php_fpm_CONF=${prefix}/etc/php-fpm.conf
php_fpm_PID=/home/php/pid/php-fpm.pid
php_opts="--fpm-config $php_fpm_CONF --pid $php_fpm_PID"
wait_for_pid () {
try=0
while test $try -lt 35 ; do
case "$1" in
'created')
if [ -f "$2" ] ; then
try=''
break
fi
;;
'removed')
if [ ! -f "$2" ] ; then
try=''
break
fi
;;
esac
echo -n .
try=`expr $try + 1`
sleep 1
done
}
case "$1" in
start)
echo -n "Starting php-fpm..."
$php_fpm_BIN --daemonize $php_opts
if [ "$?" != 0 ] ; then
echo " failed"
exit 1
fi
wait_for_pid created $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed"
exit 1
else
echo " done"
fi
;;
stop)
echo -n "Stoping php-fpm..."
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -QUIT `cat $php_fpm_PID`
wait_for_pid removed $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed. Use force-quit"
exit 1
else
echo " done"
fi
;;
force-quit)
echo -n "Terminating php-fpm "
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -TERM `cat $php_fpm_PID`
wait_for_pid removed $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed"
exit 1
else
echo " done"
fi
;;
restart)
$0 stop
$0 start
;;
reload)
echo -n "Reload service php-fpm "
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -USR2 `cat $php_fpm_PID`
echo " done"
;;
*)
echo "Usage: $0 {start|stop|force-quit|restart|reload}"
exit 1
;;
esac
10.创建目录并修改权限，重启nginx服务：
mkdir -p /home/php/log
mkdir -p /home/php/pid
chown -R www:www /home/php/log
chown -R www:www /home/php/pid
service nginx restart
11.添加php-fpm系统服务：
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig --level 2345 php-fpm on
chkconfig --list | grep php-fpm
12.启动php-fpm服务：
service php-fpm start
ps -aux | grep php-fpm
netstat -anptu | grep 9000
13.配置php测试页：
vim /home/www/html/phpinfo.php
如何安装php的扩展bcmath
为了让网站成功运行，就需要在php中增加bcmath这个扩展（其实默认的php中已经存在bcmath扩展，但是没有安装编译）
安装php的扩展bcmath具体步骤如下（以下操作均在wdcp 2.4的环境中）：
1、ssh登陆vps控制台后，进入要安装的扩展的源码目录:cd /root/lanmp/php-5.2.17/ext/bcmath
2、运行phpize，这是wdcp中的路径: /www/wdlinux/php/bin/phpize
出现如下提示:
configuring for:
php api version:
20041225
zend module api no: 20060613
zend extension api no: 220060519
3、编译安装：
./configure --with-php-config=/www/wdlinux/php/bin/php-config
make
make install
4、增加到配置文件php.ini里
vi /www/wdlinux/etc/php.ini
在最后增加：extension=bcmath.so
5、重启服务
service httpd restart
service nginxd restart
然后就大功告成
如何安装新的PHP扩展模块
php安装好后，可能在初次安装时，会有些模块会有遗漏，但是我们又不想重新编译php，因为耗时是比较长的。我们可不可以在不重新编译安装php的情况下，来为php单独添加某一个模块呢？查找资料，发现还是有方法的，重点就是phpize了，于是写了这篇文章.
下面我们就以单独为php加载mysqli模块为例，演示如何动态为php添加模块。
1、找到php原码安装文件
2、cd /home/php/ext/myslqi
3、运行 /usr/local/php/bin/phpize
4、/configure –with-php-config=/usr/local/php/bin/php-config
5、make make install
6、安装完成之后会在系统/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/这个目录下面生成mysqli.so的库文件
7、编辑php.ini文件,指定php到哪人目录读取模块
vi /usr/local/php/etc/php.ini
extension_dir=”/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613″
extension=mysqli.so
8、重启php服务 /usr/local/php/sbin/php-fpm restart
7、/usr/local/php/bin/php -m|grep mysqli 查看mysqli.so是否存在
如果步骤正确，你的人口也不差的情况下，应该这样php的动态模块加载就完成了。
