nginx 的介绍我就不罗嗦了,先说下系统的安装环境。
0. 安装环境
系统:Ubuntu 14.04
PHP 版本:5.5.9
已有服务器软件:Apache (基本不影响,后文会提到)
1.安装 Nginx
sudo apt-get install nginx
#打开配置文件sudo vim /etc/nginx/sites-available/default
然后按以下两处修改(为了不和 Apache 冲突):
server { #修改这里 我将 80 改为 88 listen 88 default_server; #还有这里 同样改为你想要的监听端口 listen [::]:88 default_server ipv6only=on; .....
2.安装 php5-fpm
同样使用 apt-get:
sudo apt-get install php5-fpm
同样打开配置文件:
#打开配置文件sudo vim /etc/nginx/sites-available/default
server { listen 88 default_server; listen [::]:88 default_server ipv6only=on; root /usr/share/nginx/html; #修改这里,在 index 后添加 index.php index index.php index.html index.htm; # Make site accessible from http://localhost/ server_name localhost; ....
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { # fastcgi_split_path_info ^(.+\.php)(/.+)$; # # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini # # # With php5-cgi alone: # fastcgi_pass 127.0.0.1:9000; # # With php5-fpm: fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; }
#这一句虽然没必要但可以给你检查配置文件的错误sudo nginx -s reload#重启 php5-fpmsudo /etc/init.d/php5-fpm restart #重启 nginxsudo /etc/init.d/nginx restart
#修改权限sudo chmod 777 /usr/share/nginx/html/#新建测试文件vim /usr/share/nginx/html/index.php
<?phpphpinfo ();?>
问题:安装后打开网页时出现 “502 Bad Gateway”
有的同学可能按照网上某些教程安装之后,测试时显示 “502 Bad Gateway”,噢,不要紧张,因为教程是错的而已....
不少教程是比较久之前的,所以在修改配置文件时,会告诉你注释得到这三行:
location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi_params;}
#php5-fpm 的配置文件sudo vim /etc/php5/fpm/pool.d/www.conf
; The address on which to accept FastCGI requests.; Valid syntaxes are:; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific address on; a specific port;; 'port' - to listen on a TCP socket to all addresses on a; specific port;; '/path/to/unix/socket' - to listen on a unix socket.; Note: This value is mandatory.listen = /var/run/php5-fpm.sock
解决方法:
打开 nginx 配置文件:
#打开配置文件sudo vim /etc/nginx/sites-available/default
location ~ \.php$ { # fastcgi_pass 127.0.0.1:9000; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; }
