Nginx 在RedHat5安装过程

一、Nginx相关资料

  主站：http://www.nginx.org/

  Nginx中文维基:http://wiki.nginx.org/NginxChs

  Nginx中文资料：http://blog.s135.com/index.php

                          http://www.51nginx.net/

二、创建www用户和组

/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data0/htdocs/blog
chmod +w /data0/htdocs/blog
chown -R www:www /data0/htdocs/blog
mkdir -p /data0/htdocs/www
chmod +w /data0/htdocs/www
chown -R www:www /data0/htdocs/www

三、安装nginx-1.0.4
　　1、安装Nginx所需的pcre库：

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ pcre-8.12.tar.gz

tar zxvf pcre-8.12.tar.gz
cd pcre-8.12/
./configure
make && make install

 
  可能需要的库：

     x86_64 系统

wget http://blog.s135.com/soft/linux/nginx_php/rpm/x86_64/libjpeg-devel-6b-33.x86_64.rpm
rpm -ivh libjpeg-devel-6b-33.x86_64.rpm
wget http://blog.s135.com/soft/linux/nginx_php/rpm/x86_64/freetype-devel-2.1.9-1.x86_64.rpm
rpm -ivh freetype-devel-2.1.9-1.x86_64.rpm
wget http://blog.s135.com/soft/linux/nginx_php/rpm/x86_64/libpng-devel-1.2.7-1.x86_64.rpm
rpm -ivh libpng-devel-1.2.7-1.x86_64.rpm

 

　　2、安装Nginx

tar zxvf nginx-1.0.4.tar.gz
cd nginx-1.0.4/
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install

　　3、创建Nginx日志目录

mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs

　　4、创建Nginx配置文件
　　①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件：

rm -f /usr/local/webserver/nginx/conf/nginx.conf
vi /usr/local/webserver/nginx/conf/nginx.conf

内容如下：

user  www www;
worker_processes  4;

error_log  /usr/local/loadbalancer/logs/nginx_error.log  crit;

pid       /usr/local/loadbalancer/nginx/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process. 
worker_rlimit_nofile 1024;


events {
     use epoll;
    worker_connections  1024;
}


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"';

    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;

    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;

    
    server {
        listen       80;
        server_name  www.xxx.com xxx.com *.xxx.com;

        location / {
           proxy_pass  http://www.xxx.com:8080;
        }

        log_format  access  '$remote_addr - $remote_user [$time_local] "$request" '
              '$status $body_bytes_sent "$http_referer" '
              '"$http_user_agent" $http_x_forwarded_for';
        access_log  /usr/local/loadbalancer/logs/xxx_access.log  access;
    }

    server {
        listen       80;
        server_name  www.ffff.com ffff.com *.ffff.com;

        location / {
           proxy_pass  http://www.fff.com:8082;
        }

        log_format  access  '$remote_addr - $remote_user [$time_local] "$request" '
              '$status $body_bytes_sent "$http_referer" '
              '"$http_user_agent" $http_x_forwarded_for';
        access_log  /usr/local/loadbalancer/logs/fff_access.log  access;
    }
}

 

　　②、在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件：

vi /usr/local/webserver/nginx/conf/fcgi.conf

　　输入以下内容：

引用

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx;

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_FILENAME    $document_root$fastcgi_script_name;
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  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;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

　　5、启动Nginx

ulimit -SHn 65535
/usr/local/webserver/nginx/sbin/nginx

---

　　 六、在不停止Nginx服务的情况下平滑变更Nginx配置
　　1、修改/usr/local/webserver/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：

/usr/local/webserver/nginx/sbin/nginx -t

　　如果屏幕显示以下两行信息，说明配置文件正确：
　　 the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
　　the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully

　　2、平滑重启：
　　①、对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：

/usr/local/webserver/nginx/sbin/nginx -s reload

---

　　 七、编写每天定时切割Nginx日志的脚本
　　1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh

vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh

　　输入以下内容：

引用

#!/bin/bash
# This script run at 00:00

# The Nginx logs path
logs_path="/usr/local/webserver/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`

　　2、设置crontab，每天凌晨00:00切割nginx访问日志

crontab -e

　　输入以下内容：

引用

00 00 * * * /bin/bash  /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
