本次安装基于系统CentOS Linux release 7.2.1511 (Core)
1.环境配置
安装前的环境准备：
##安装make，已安装，可省略
$yum -y install gcc automake autoconf libtool make
##安装gcc g++ glibc库
$yum -y install gcc gcc-c++ glibc
##安装所需的包
$yum -y install libmcrypt-devel mhash-devel libxslt-devel
libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel
zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel
ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel
krb5 krb5-devel libidn libidn-devel openssl openssl-devel
安装的包有些多，以上安装可分批或者一个一个进行，如yum -y install libmcrypt-devel，一般来说均可安装成功，如果失败可多试几次。
2.php安装
下载源码编译安装
##下载源码
$wget http://am1.php.net/distributions/php-7.2.2.tar.gz
##解压
$tar -zxvf php-7.2.2.tar.gz
##创建安装目录
$mkdir php7
$mv php-7.2.2 php7
$cd php7/php-7.2.2/
## 编译前配置
$./configure --prefix=/home/test/php7 --with-config-file-path=/home/test/php7/etc --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-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 \

--enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm \
--enable-xml --enable-zip --with-ldap
##编译时间略长，耐心等待
$make
##安装
$make install
配置php相关文件
##php.ini，编译配置时配在php7/etc目录下
$cp php-7.2.2/php.ini-development ../etc/php.ini
##php-fpm.conf
$cp ../etc/php-fpm.conf.default ../etc/php-fpm.conf
##www.conf
$cp ../etc/php-fpm.d/www.conf.default ../etc/php-fpm.d/www.conf
修改配置
- php.ini
原cgi.force_redirect = 1被注释，需要放开且修改为cgi.force_redirect = 0 - php-fpm.conf
修改错误日志路径error_log = log/php-fpm.log -
www.conf
修改用户和用户组选项user = nginx、group = nginx
设置php环境变量
$vim /etc/profile
##加上下面这句话
export PATH=/home/test/php7/bin:/home/test/php7/sbin:$PATH
$source /etc/profile
$php -v
PHP 7.2.2 (cli) (built: Feb 10 2018 16:13:50) ( NTS )

启动php
$/home/test/php7/sbin/php-fpm
##检查进程是否启动
$ps -ef | grep php
root 41963 1 0 18:04 ? 00:00:00 php-fpm: master process (/home/test/php7/etc/php-fpm.conf)
nginx 41964 41963 0 18:04 ? 00:00:00 php-fpm: pool www
nginx 41965 41963 0 18:04 ? 00:00:00 php-fpm: pool www
##检查端口9000是否活着
$netstat -anp | grep 9000
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 41963/php-fpm: mast
3.修改nginx配置
Nginx安装参考：Nginx源码安装
找到nginx配置nginx.conf，修改如下，修改后重启nginx：
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
##添加index.php
index index.php index.html index.htm;
}
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
##注意这里有关php的location注释要放开
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
##注意脚本目录路径使用绝对路径更清晰
fastcgi_param SCRIPT_FILENAME /home/test/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
}
4.测试
在nginx/html目录下建文件index.php，文件内容如下
<?php
phpinfo();
?>
访问 http://IP/index.php (IP为服务器的ip地址)可得如下页面即是成功
php.png
注意：nginx的用户对html目录必须有读写权限；最好nginx，php的用户保持统一
