6. Nginx + PHP + FastGCI安装
LNAMP Linux Nginx Apache Mysql PHP
Nginx + PHP（fast CGI）
可以理解为一个php加速的一个接口
Php-fpm 可以实现fastcgi协议需要的进程池，php-fpm实现的fastcgi进程叫php-cgi，所以php-fmp其实是他自身的fastcgi 或 php-cgi进程管理器
Ngix+FastCGI安装
前期准备工作：
#yum install gd curl curl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel mariadb mariadb-server mariadb-devel -y
[root@nginx php-5.3.10]# systemctl start mariadb.service
[root@nginx php-5.3.10]# systemctl enable mariadb.service
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
注意：如果碰到以下的错误，查看一下解决方案
配置之前需要做一个软链接
因为在64位的linux系统中，libmysqlclient 默认安装到了 /usr/lib64/mysql/ 目录下，但是php编译时，要去/usr/lib目录下查找
# ln -s /usr/lib64/mysql/libmysqlclient.so.18.0.0 /usr/lib/libmysqlclient.so
否则会报错：
configure: error: Cannot find libmysqlclient under /usr.
Note that the MySQL client library is not bundled anymore!
#使用编译安装php-fast
下载php7.1.12
解压---配置---
[root@nginx ]# tar xvf php-7.1.12.tar.gz
[root@nginx php-7.1.12]# ./configure --prefix=/usr/local/php7.1 --enable-fpm --enable-debug --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --enable-mbstring --with-curl --with-mysqli=/usr/bin/mysql_config
---编译---安装---
[root@nginx php-7.1.12]# make

报错：
[root@nginx ~]# /etc/init.d/php-fpm start
Starting php-fpm [29-Nov-2017 16:43:01] WARNING: Nothing matches the include pattern '/usr/local/php7.1/etc/php-fpm.d/*.conf' from /usr/local/php7.1/etc/php-fpm.conf at line 125.

解决：
[root@nginx php-fpm.d]# pwd
/usr/local/php7.1/etc/php-fpm.d
[root@nginx php-fpm.d]# cp www.conf.default www.conf
如果还有报错可能是配置文件php-fpm.conf最后一行，默认是注释的，去掉注释即可。
include=/usr/local/php7.1/etc/php-fpm.d/*.conf
安装完成：
Wrote PEAR system config file at: /usr/local/php7.1/etc/pear.conf
You may want to add: /usr/local/php7.1/lib/php to your php.ini include_path
/root/php-7.1.12/build/shtool install -c ext/phar/phar.phar /usr/local/php7.1/bin
ln -s -f phar.phar /usr/local/php7.1/bin/phar
