1.获取基本的相关的开源程序：

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers

3.先通过命令 rpm -qa | grep libjpeg 类似的命令去检查上面这些包是否存在，否则，安装会出现缺少库支持

rpm -ivh (filename) 是安装RPM包的命令

4.获取nginx的源代码包

wget http://sysoev.ru/nginx/nginx-0.8.46.tar.gz

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.10.tar.gz (安装nginx需要的库支持)

5.创建www:www用户和组

groupadd www

useradd -g www www

将nginx 安装在/usr/local/webserver/ 下面

以后就将web程序放在/var/www/下面

@1安装Nginx所需的pcre库：

tar zxvf pcre-8.10.tar.gz
cd pcre-8.10/
./configure
make && make install
cd ../

@2安装Nginx

tar zxvf nginx-0.8.46.tar.gz
cd nginx-0.8.46/
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
cd ../

@3创建Nginx日志目录

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

网上推荐的一份nginx.conf

mv /usr/local/webserver/nginx/conf/nginx.conf /usr/local/webserver/nginx/conf/nginx.conf.bak
vi /usr/local/webserver/nginx/conf/nginx.conf

user  www www;

worker_processes 8;

error_log  /data1/logs/nginx_error.log  crit;

pid        /usr/local/webserver/nginx/nginx.pid;

    	{

    	}

	{
		expires      1h;
	}    

              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  /data1/logs/access.log  access;
      }




}

@1设置用户最大打开文件数

ulimit -SHn 65535

@2启动nginx

/usr/local/webserver/nginx/sbin/nginx

@1开机自动启动

vi /etc/rc.local

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

@2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

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

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