`1、安裝環境依賴包`
[root@localhost ~]# yum -y install gd \ //安裝依賴環境
> libjpeg libjpeg-devel \
> libpng libpng-devel \
> freetype freetype-devel \
> libxml2 libxml2-devel \
> zlib zlib-devel \
> curl curl-devel \
> openssl openssl-devel
`2、編譯安裝`
[root@localhost ~]# cd /opt
[root@localhost opt]# rz
[root@localhost opt]# ls
Discuz_X3.4_SC_UTF8.zip nginx-1.22.0 nginx-1.22.0.tar.gz php-7.1.10.tar.bz2 rh
[root@localhost opt]# tar xf php-7.1.10.tar.bz2 //解壓

`4、調整PHP配置檔案`
php有三個配置檔案：
php.ini 主配置檔案
php-fpm.conf 程序服務配置檔案
www.conf 擴充套件配置檔案
修改主配置檔案
[root@localhost php-7.1.10]# cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini
[root@localhost php-7.1.10]# vim /usr/local/php/lib/php.ini
939 date.timezone = Asia/Shanghai //修改時區
1170 mysqli.default_socket = /var/lib/mysql/mysql.sock //指明mysql檔案位置
修改程序服務配置檔案
[root@localhost php-7.1.10]# cd /usr/local/php/etc/
[root@localhost etc]# ls
pear.conf php-fpm.conf.default php-fpm.d
[root@localhost etc]# cp php-fpm.conf.default php-fpm.conf
[root@localhost etc]# vim php-fpm.conf
17 pid = run/php-fpm.pid //去掉";"註釋
修改擴充套件配置檔案
[root@localhost etc]# cd /usr/local/php/etc/php-fpm.d/
[root@localhost php-fpm.d]# ls
www.conf.default
[root@localhost php-fpm.d]# cp www.conf.default www.conf

[root@localhost fpm]# systemctl daemon-reload
[root@localhost fpm]# systemctl start php-fpm.service
[root@localhost fpm]# ss -natp |grep 9000
LISTEN 0 128 127.0.0.1:9000 *:* users:(("php-fpm",pid=15127,fd=0),("php-fpm",pid=15126,fd=0),("php-fpm",pid=15125,fd=6))
