//取消65到71行的注释，并在第69行添加nginx网站发布目录的绝对路径

//检测语法
[root@localhost conf]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
//没有问题

[root@localhost conf]# nginx -s reload
nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"
//重读配置文件的时候，报了这样的一个错，
解决：

[root@localhost logs]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
[root@localhost logs]# nginx -s reload

关闭防火墙

[root@localhost sbin]# systemctl stop firewalld
[root@localhost sbin]# setenforce 0

访问

安装mysql
具体安装请看mysql安装

//nginx和mysql的端口都起来了
[root@localhost lnmp]# ss -antl

安装php

安装相应的依赖包

[root@localhost ~]# yum -y install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libicu-devel libjpeg libjpeg-devel libpng libpng-devel openldap-devel  pcre-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel mhash mhash-devel

//有状态，但是端口没有起来

root@localhost etc]# cd php-fpm.d/
[root@localhost php-fpm.d]# ls

[root@localhost php-fpm.d]# vim www.conf 

; Note: This value is mandatory.
;listen = /run/php-fpm/www.sock
listen = 0.0.0.0:9000


重启php，就会发现php的端口起来了
[root@localhost ~]# systemctl restart php-fpm
[root@localhost ~]# ss -antl

在nginx的访问页面目录里添加一个php的语法

[root@localhost ~]# cd /usr/local/nginx/html/
[root@localhost html]# ls
50x.html  index.html
[root@localhost html]# vim index.php
[root@localhost html]# cat index.php 
<?php
    phpinfo();
?>

[root@localhost ~]# vim /etc/php.ini 

;cgi.fix_pathinfo=0
//把这里的1 改成0

nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
//如果报这个错，就把配置文件中第九行的注释取消掉
[root@localhost conf]# vim nginx.conf
  9 pid        logs/nginx.pid;




 35     server {
 36         listen       80;
 37         server_name  localhost;
 38         root /www;   //添加这行
 39         index index.php index.html;  //添加这行
 40         #charset koi8-r;

重读nginx的配置文件，重启nginx

[root@localhost conf]# nginx -s reload
[root@localhost conf]# nginx -s stop
[root@localhost conf]# nginx
