Nginx 0.7.x + PHP 5.2.10（FastCGI）搭建胜过Apache十倍的Web服务器 安装与配置（4）

 

　　三、安装Nginx 0.7.61
　　1、安装Nginx所需的pcre库：

tar zxvf pcre-7.9.tar.gz
cd pcre-7.9/
./configure
make && make install
cd ../

　　2、安装Nginx

tar zxvf nginx-0.7.61.tar.gz
cd nginx-0.7.61/
./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

　　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.

#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
{
    listen       80;
    server_name www.s135.com;
    index index.html index.htm index.php;
    root /data0/htdocs/www;

    location ~ .*/.(php|php5)?$
    {     
      #fastcgi_pass unix:/tmp/php-cgi.sock;
      fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
      include fcgi.conf;
    }

    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;
}

server
{
    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

　　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 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：

引用
ulimit -SHn 51200
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/nginx/sbin/nginx

--------------------------------------------------------------------------------

　　五、优化Linux内核参数

vi /etc/sysctl.conf

　　在末尾增加以下内容：

引用
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768

net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024 65535

　　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

　　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
