Nginx 运维架构之(Nginx+PHP)

释放双眼,带上耳机,听听看~!

  1、首先我们来看下web服务器的排名情况

Nginx 运维架构之(Nginx+PHP)

可以看到Nginx占有30.6%,Apache 52.0%,Nginx特点如下

1、配置简单,灵活,轻量。

2、高并发(静态小文件),静态几万的并发

3、占用资源少

4、功能种类比较多(web,cache,proxy),每一个功能都不是特别强

5、支持epoll模型,使得nginx可以支持高并发 Apache 选择 select模型

6、nginx可以搭配动态服务(FASTCGI接口)

6、利用nginx可以对ip限速,可以限制连接数

并发能力

nginx 1-3万  php 300-800  db 300-800.日pv2000万以下,并发1万以下都可以用nginx做反向代理

2、nginx的安装(centos6.7)

[root@centos02 tools]#  yum install pcre pcre-devel openssl-devel -y

[root@centos02 tools]# wget  http://nginx.org/download/nginx-1.6.3.tar.gz 

[root@centos02 tools]# tar xf nginx-1.6.3.tar.gz 

[root@centos02 tools]# cd nginx-1.6.3

[root@centos02 nginx-1.6.3]# useradd -s /sbin/nologin -M nginx

[root@centos02 nginx-1.6.3]# ./configure –prefix=/application/nginx-1.6.3 –user=nginx –group=nginx  –with-http_stub_status_module –with-http_ssl_module

[root@centos02 nginx-1.6.3]# make && make install    

[root@centos02 nginx-1.6.3]# ln -s /application/nginx-1.6.3/ /application/nginx

[root@centos02 nginx-1.6.3]#  /application/nginx/sbin/nginx -t   检查语法

[root@centos02 nginx-1.6.3]#  /application/nginx/sbin/nginx   启动nginx

访问下nginx服务

一份简单的nginx配置

[root@centos02 conf]# cat nginx.conf

worker_processes  2;

events {

    worker_connections  1024;

}

http {

log_format  main  ‘$remote_addr – $remote_user [$time_local] “$request” ‘

                      ‘$status $body_bytes_sent “$http_referer” ‘

                      ‘”$http_user_agent” “$http_x_forwarded_for”‘;

    include       mime.types;

    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;

    server {

        listen       80;

        server_name  www.martin.com martin.com;

        location / {

            root   html/www;

            index  index.php index.html index.htm;

        }

         

          

        location ~ .*/.(php|php5)?$ {

            root  html/www;

            fastcgi_pass 127.0.0.1:9000;

            fastcgi_index index.php;

            include fastcgi.conf;

               }

         access_log  logs/access_www.log  main;        

   }

             

    server {

        listen       80;

        server_name  bbs.martin.com;

        location / {

            root   html/bbs;

            index  index.php index.html index.htm;

        }

       

              

        location ~ .*/.(php|php5)?$ {

            fastcgi_pass 127.0.0.1:9000;

            fastcgi_index index.php;

            include fastcgi.conf;

               }

         access_log  logs/access_bbs.log  main;       

    }

###status

   server{

      listen 80;

      server_name status.martin.org;

      location / {

      stub_status on;

      access_log off;

        }

   }

}

3、数据库MySQL的安装

[root@centos02 tools]# wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.49-linux2.6-x86_64.tar.gz   

 这是个二进制包,无需编译 

[root@centos02 tools]# tar xf mysql-5.5.49-linux2.6-x86_64.tar.gz 

[root@centos02 tools]# useradd -s /sbin/nologin -M mysql

[root@centos02 tools]# mv mysql-5.5.49-linux2.6-x86_64 /application/mysql-5.5.49 

[root@centos02 tools]# ln -s /application/mysql-5.5.49/  /application/mysql

[root@centos02 tools]#  /application/mysql/scripts/mysql_install_db –basedir=/application/mysql  –datadir=/application/mysql/data/ –user=mysql

[root@centos02 tools]# sed -i ‘s#/usr/local/mysql#/application/mysql#g’ /application/mysql/support-files/mysql.server 

[root@centos02 tools]# cp /application/mysql/support-files/mysql.server /etc/init.d/mysqld 

[root@centos02 tools]# chmod +x /etc/init.d/mysqld

[root@centos02 mysql]# chown -R mysql.mysql /application/mysql/

[root@centos02 mysql]# cp support-files/my-small.cnf /etc/my.cnf
