nginx入门

安装配置

一、安装编译工具及库文件

yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel

首先要安装 PCRE
  • 1.下载安装包
    [root@cshame src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

  • 2.解压安装包
    [root@cshame src]# tar zxvf pcre-8.35.tar.gz

  • 3.进入安装包目录
    [root@cshame src]# cd pcre-8.35

  • 4.编译安装
    [root@cshame pcre-8.35]# ./configure
    [root@cshame pcre-8.35]# make && make install

  • 5.查看pcre版本
    [root@cshame pcre-8.35]# pcre-config --version

二、安装 Nginx
  • 1.下载安装包
    [root@cshame src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz

  • 2.解压安装包
    [root@cshame src]# tar zxvf nginx-1.6.2.tar.gz

  • 3.进入安装包目录
    [root@cshame src]# cd nginx-1.6.2

  • 4.编译安装
    [root@cshame nginx-1.6.2]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35 [root@cshame nginx-1.6.2]# make [root@cshame nginx-1.6.2]# make install

  • 5.查看nginx版本
    [root@cshame nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v

Nginx 配置
  • 1.创建nginx运行使用的用户www
    [root@cshame conf]# /usr/sbin/groupadd www [root@cshame conf]# /usr/sbin/useradd -g www www

  • 2.配置nginx.conf ,将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
    [root@cshame conf]# vi /usr/local/webserver/nginx/conf/nginx.conf

user www www; worker_processes 2; #设置值和CPU核心数一致 error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别 pid /usr/local/webserver/nginx/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process. worker_rlimit_nofile 65535; events { use epoll; worker_connections 65535; } http { include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" $http_x_forwarded_for';

#charset gb2312;

server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 8m;

sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 128k; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.0; gzip_comp_level 2; gzip_types text/plain application/x-javascript text/css application/xml; gzip_vary on;

#limit_zone crawler $binary_remote_addr 10m;

#下面是server虚拟主机的配置 server { listen 80;#监听端口 server_name localhost;#域名 index index.html index.htm index.php; root /usr/local/webserver/nginx/html;#站点目录 location ~ .*.(php|php5)?$ {

#fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi.conf; } location ~ .*.(gif|jpg|jpeg|png|bmp|swf|ico)$ { expires 30d;

#access_log off; } location ~ .*.(js|css)?$ { expires 15d;

#access_log off; } access_log off; } }

  • 3.检查配置文件ngnix.conf的正确性命令: [root@cshame conf]# /usr/local/webserver/nginx/sbin/nginx -t

启动 Nginx

[root@cshame conf]# /usr/local/webserver/nginx/sbin/nginx

Nginx 其他命令

/usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件 /usr/local/webserver/nginx/sbin/nginx -s reopen # 重启 Nginx /usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx

question one:

配置完成后,打开80端口,不是显示nginx默认首页,而是跳转到博客首页,打开3000端口也是跳转到博客首页。

answer one:

之前在在nginx配置的时候由于没有弄太懂,将80端口强制跳转到了3000,如果想blog.cshame.wang到3000,cshame.wang到别的端口的话,代码如下:

   server
    {
      server_name blog.cshame.wang
      listen 80;
       location / {
         proxy_pass http://127.0.0.1:3000;
         proxy_set_header X-Real-IP $remote_addr;
       }
     }

   server
   {
     listen       80;
     server_name  cshame.wang;
     location / {
        proxy_pass http://127.0.0.1:9000;
        proxy_set_header X-Real-IP $remote_addr;
     }
   }
