php安装
准备工作
1，新建存储目录
#存放项目运行目录
mkdir -p /data/wwwroot
#存放日志目录
mkdir -p /data/wwwlog
#存放文件目录
mkdir -p /data/source
2，新建用户
useradd -r -s/sbin/nologin php-fpm
3，下载解压软件安装包
cd /data/source
wget http://php.net/get/php-7.2.2.tar.gz/from/this/mirror
mv mirror php-7.2.2.tar.gz
tar zxvf php-7.2.2.tar.gz
cd php-7.2.2
4，安装依赖库
yum -y install libxml2libxml2-devel openssl openssl-devel curl-devel libjpeg-devel libpng-devel freetype-devel libmcrypt-devel libxslt libicu-devel libxslt-devel
5，编译安装
./configure \
--prefix=/usr/local/php-7.2.2 \
--with-mhash \
--with-openssl \
--with-config-file-path=/usr/local/php-7.2.2/etc \
--disable-short-tags \
--enable-fpm \
--with-fpm-user=php-fpm --with-fpm-group=php-fpm \
--enable-xml \
--with-libxml-dir \
--enable-bcmath \
--enable-calendar \
--enable-intl \
--enable-mbstring \
--enable-pcntl \
--enable-shmop \
--enable-soap \
--enable-sockets \
--enable-zip \
--enable-mbregex \
--enable-mysqlnd \
--enable-mysqlnd-compression-support \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-gd \
--enable-ftp \
--with-curl \
--with-xsl \
--with-iconv \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--enable-sysvsem \
--enable-inline-optimization \
--with-xmlrpc \
--with-gettext
make -j 4 && make install
6，建立软链
ln -s/usr/local/php-7.2.2/ /usr/local/php
ln -s/usr/local/php/bin/php /usr/local/bin
ln -s/usr/local/php/sbin/php-fpm /usr/local/sbin
#默认安装好之后，你会发现/usr/local/php/etc下面没有php.ini文件，这个去哪里要呢？在php7的源码安装包里
cd /data/source/php-7.2.2
cp ./php.ini-development ./php.ini-production /usr/local/php/etc
cp /usr/local/php/etc/php.ini-development /usr/local/php/etc/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
8，建立软链
ln -s/usr/local/php/etc/php.ini /usr/local/etc/
ln -s/usr/local/php/etc/php-fpm.conf /usr/local/etc/
ln -s/usr/local/php/etc/php-fpm.d/www.conf /usr/local/etc/
9，启动php-fpm 服务
/usr/local/sbin/php-fpm
10，查看是否启动
netstat -lnt | grep9000
php -i|grep php.ini
12，杀死php-fpm
killall php-fpm
配置环境变量，加入全局命令（看需要配置）
vim/etc/profile
export PATH=/usr/local/php/bin:$PATH
source /etc/profile
