centos 安装php

Linux版本：64位CentOS 6.6

Nginx版本：nginx1.8.0

php版本：php-7.0.2

(一)下载 （php-7.1.18.tar.gz： http://cn2.php.net/get/php-7.1.18.tar.gz/from/this/mirror）

# wget http://php.net/get/php-7.0.2.tar.gz/from/a/mirror

建议安装之前先看看安装帮助文件INSTALL

（二）解压安装
# tar zxvf php-7.0.2.tar.gz

# cd php-7.0.2

（三）首先查看安装帮助
# ./configure --help

./configure --prefix=/usr/local/php
--with-curl
--with-freetype-dir
--with-gd
--with-gettext
--with-iconv-dir
--with-kerberos
--with-libdir=lib64
--with-libxml-dir
--with-mysqli
--with-openssl
--with-pcre-regex
--with-pdo-mysql
--with-pdo-sqlite
--with-pear
--with-png-dir
--with-xmlrpc
--with-xsl
--with-zlib
--enable-fpm
--enable-bcmath
--enable-libxml
--enable-inline-optimization
--enable-gd-native-ttf
--enable-mbregex
--enable-mbstring
--enable-opcache
--enable-pcntl
--enable-shmop
--enable-soap
--enable-sockets
--enable-sysvsem
--enable-xml
--enable-zip

如果配置错误，需要安装需要的模块，直接yum一并安装依赖库

# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel mysql pcre-devel

注意：安装php7beta3的时候有几处配置不过去，需要yum一下，现在php-7.0 .2已经不用这样了。
# yum -y install curl-devel
# yum -y install libxslt-devel

（四）编译安装

# make && make install

(五)配置文件
# cp php.ini-development /usr/local/php/lib/php.ini
# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
# cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm

vi /usr/local/php/etc/php-fpm.d/www.conf
group =www
user=www

需要注意的是php7中www.conf这个配置文件配置phpfpm的端口号等信息，如果你修改默认的9000端口号需在这里改，再改nginx的配置
启动

# /etc/init.d/php-fpm

查看phpinfo()

（六）、php-fpm开机启动
1、在/etc/init.d/目录下创建脚本
vi /etc/init.d/php-fpm
2、更改脚本权限
chown -R www:www /etc/init.d/php-fpm

3、编写脚本内容

#!/bin/sh
# php-fpm - this script starts and stops the php-fpm daemin
# chkconfig: - 85 15
# processname: php-fpm
# config: /usr/local/php/etc/php-fpm.conf
set -e
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="php-fpm daemon"
NAME=php-fpm
DAEMON=/usr/local/php/sbin/$NAME #这里设成自己的目录
CONFIGFILE=/usr/local/php/etc/php-fpm.conf #这里设成自己的目录
PIDFILE=/usr/local/php/var/run/$NAME.pid #这里设成自己的目录（vi php-fpm.conf 去掉里面那个 pid = run/php-fpm.pid 前面的分号然后再启动php-fpm才能自动生成的）
SCRIPTNAME=/etc/init.d/$NAME #这里设成自己的目录
# If the daemon file is not found, terminate the script.
test -x $DAEMON || exit 0
d_start(){
$DAEMON -y $CONFIGFILE || echo -n " already running"
}
d_stop(){
kill -QUIT `cat $PIDFILE` || echo -n " no running"
}
d_reload(){
kill -HUP `cat $PIDFILE` || echo -n " could not reload"
}
case "$1" in
start)
echo -n "Starting $DESC: $NAME"
d_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
d_stop
echo "."
;;
reload)
echo -n "Reloading $DESC configuration..."
d_reload
echo "Reloaded."
;;
restart)
echo -n "Restarting $DESC: $NAME"
d_stop
# Sleep for two seconds before starting again, this should give the nginx daemon some time to perform a graceful stop
sleep 2
d_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload)" >&2
exit 3
;;
esac
4、设置开机启动
#chkconfig php-fpm on
