Nginx 0.7.x + PHP 5.2.8（FastCGI）搭建胜过Apache十倍的Web服务器（第4版）四

三、安装Nginx 0.7.30

　　1、安装Nginx所需的pcre库：

tar zxvf pcre-7.8.tar.gz

cd pcre-7.8/

./configure

make && make install

cd ../

　　2、安装Nginx

tar zxvf nginx-0.7.30.tar.gz

cd nginx-0.7.30/

./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module

　　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

　　输入以下内容：

引用

user  www www;

worker_processes 8;

error_log  /data1/logs/nginx_error.log  crit;

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

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

worker_rlimit_nofile 51200;

events 

{

 use epoll;

 worker_connections 51200;

}

http 

 include       mime.types;

 default_type  application/octet-stream;

 #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;

 server

 {

   listen       80;

   server_name  blog.s135.com;

   index index.html index.htm index.php;

   root  /data0/htdocs/blog;

   #limit_conn   crawler  20;    

   location ~ .*\.(php|php5)?$

   {      

     #fastcgi_pass  unix:/tmp/php-cgi.sock;

     fastcgi_pass  127.0.0.1:9000;

     fastcgi_index index.php;

     include fcgi.conf;

   }

   location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$

   {

     expires      30d;

   location ~ .*\.(js|css)?$

     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;

     }

   server_name  www.s135.com;

   root  /data0/htdocs/www;

   log_format  wwwlogs  '$remote_addr - $remote_user [$time_local] "$request" '

              '$status $body_bytes_sent "$http_referer" '

              '"$http_user_agent" $http_x_forwarded_for';

   access_log  /data1/logs/wwwlogs.log  wwwlogs;

 }

   listen  80;

   server_name  status.blog.s135.com;

   location / {

   stub_status on;

   access_log   off;

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

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

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 51200

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

　　四、配置开机自动启动Nginx + PHP

vi /etc/rc.local

　　在末尾增加以下内容：

/usr/local/webserver/php/sbin/php-fpm start

　　五、优化Linux内核参数

vi /etc/sysctl.conf

net.ipv4.tcp_fin_timeout = 30

net.ipv4.tcp_keepalive_time = 300

net.ipv4.tcp_syncookies = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_tw_recycle = 1

net.ipv4.ip_local_port_range = 5000    65000

　　使配置立即生效：

/sbin/sysctl -p

　　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、这时，输入以下命令查看Nginx主进程号：

ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'

　　屏幕显示的即为Nginx主进程号，例如：

　　6302

　　这时，执行以下命令即可使修改过的Nginx配置文件生效：

kill -HUP 6302

　　或者无需这么麻烦，找到Nginx的Pid文件：

kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`

　　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

#!/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

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