Nginx日记

一.YUM安装Nginx

系统：CentOS release 6.6 (Final)

创建  /etc/yum.repos.d/nginx.repo 这个文件，内容为：

[nginx]name=nginx repobaseurl=http://nginx.org/packages/centos/6/$basearch/gpgcheck=0enabled=1

yum install nginx

二.源码安装

./configure    --sbin-path=/usr/local/nginx/nginx    --conf-path=/usr/local/nginx/nginx.conf    --pid-path=/usr/local/nginx/nginx.pid    --with-http_ssl_module    --with-pcre=../pcre-4.4    --with-zlib=../zlib-1.1.3

三.Nginx启动和停止

关闭重启nginx时，需加上-s选项平滑重启关闭

nginx -s signal
Where signal may be one of the following:

stop — 快速关闭
quit — 正常关闭
reload — 重新加载配置文件
reopen — 打开日志文件
四.配置文件

配置一般有两个模块

http{

 server{

}

}

http {    
server {    location / {        root /data/www;    }    location /images/ {        root /data;    }}
}
代理配置
server {    location / {        proxy_pass http://localhost:8080;    }    location /images/ {        root /data;    }}

server {    listen 8080;    root /data/up1;    location / {    }}

图片路径配置

配置支持PHP
location ~ [^/]\.php(/|$){  try_files $uri =404;  fastcgi_pass  unix:/tmp/php-cgi.sock;  fastcgi_index index.php;
   fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;   fastcgi_param  QUERY_STRING       $query_string;   fastcgi_param  REQUEST_METHOD     $request_method;   fastcgi_param  CONTENT_TYPE       $content_type;   fastcgi_param  CONTENT_LENGTH     $content_length;   fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;   fastcgi_param  REQUEST_URI        $request_uri;   fastcgi_param  DOCUMENT_URI       $document_uri;   fastcgi_param  DOCUMENT_ROOT      $document_root;   fastcgi_param  SERVER_PROTOCOL    $server_protocol;   fastcgi_param  HTTPS              $https if_not_empty;   fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;   fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;   fastcgi_param  REMOTE_ADDR        $remote_addr;   fastcgi_param  REMOTE_PORT        $remote_port;   fastcgi_param  SERVER_ADDR        $server_addr;   fastcgi_param  SERVER_PORT        $server_port;   fastcgi_param  SERVER_NAME        $server_name;}
重写URL配置
location /users/ {    rewrite ^/users/(.*)$ /show?user=$1 break;}
