centos7安装并配置nginx+php

1. 安装nginx

yum install nginx

2. 设置nginx开启起动

systemctl start nginx

3. 测试
   访问http://你的域名或IP/
   
4. 查看nginx安装位置

whereis nginx

nginx: /usr/sbin/nginx /etc/nginx /usr/share/nginx /usr/share/man/man3/nginx.3pm.gz /usr/share/man/man8/nginx.8.gz

5. 安装php

yum install php php-mysql php-fpm

安装过程中经常会见到如下问题：
2:postfix-2.10.1-6.el7.x86_64 有缺少的需求 libmysqlclient.so.18()(64bit)
2:postfix-2.10.1-6.el7.x86_64 有缺少的需求 libmysqlclient.so.18(libmysqlclient_18)(64bit)
解决方法：
把php-mysql换成php-mysqlnd
即执行

yum install php php-mysqlnd php-fpm

6. 配置php处理器

vim /etc/php.ini

查找cgi.fix_pathinfo
将 ;cgi.fix_pathinfo=1改为cgi.fix_pathinfo=0
7. 配置www.conf

vim /etc/php-fpm.d/www.conf

将
user = nobody
group = nobody
改为
user = nginx
group = nginx
前提是已经创建了nginx用户和nginx组。
8. 起动php-fpm

systemctl start php-fpm

9. 设置php-fpm开机启动

systemctl enable php-fpm

10. 配置nginx
    打开/etc/nginx/conf.d/default.conf，如果不存在则创建
    粘贴
    server {
    listen 80;
    server_name server_domain_name_or_IP;

    note that these lines are originally from the "location /" block

    root /usr/share/nginx/html;
    index index.php index.html index.htm;

    location / {
    try_files $uri $uri/ =404;
    }
    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
    root /usr/share/nginx/html;
    }

    location ~ .php$ {
    try_files $uri =404;
    root /usr/share/nginx/html;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi.conf;
    }
    }

11. 重起nginx
