Tutorial on installing nginx + php + memcached_PHP under ubuntu

1, install nginx

sudo apt-get install nginx

All configuration files are under /etc/nginx, and the virtual host configuration is under /etc/nginx/sites-available

The program file is in /usr/sbin/nginx

The log is placed in /var/log/nginx

And the startup script nginx has been created under /etc/init.d/

The default virtual host directory is set to /var/www/nginx-default

Start nginx

sudo /etc/init.d/nginx start
sudo /etc/init.d/nginx reload

2, install php

sudo apt-get install php5-cli php5-cgi php5-mysql

3. Install FastCgi

<span> apt-get install php5-cgi</span>

You can also install spawn-fcgi. spawn-fcgi is a fastcgi management program and is an independent project from Lighthttpd. In actual operations, you can use php-fpm (php's fastcgi php manager). php-fpm comes with php 5.3.3, but my current version is php 5.3.2.

Use spawn-fcgi to execute

sudo /usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid

Parameter meaning:

* -f 指定调用FastCGI的进程的执行程序位置，根据系统上所装的PHP的情况具体设置 
* -a 绑定到地址addr 
* -p 绑定到端口port 
* -s 绑定到unix socket的路径path 
* -C 指定产生的FastCGI的进程数，默认为5（仅用于PHP） 
* -P 指定产生的进程的PID文件路径 
* -u和-g FastCGI使用什么身份（-u 用户 -g 用户组）运行，Ubuntu下可以使用www-data，其他的根据情况配置，如nobody、apache等

Restart fcgi

php-cgi: kill the process first

sudo killall -HUP php5-cgi

Restart fcgi

4, configure nginx to support php

Modify nginx configuration file: /etc/nginx/sites-available/default Modify host name:

server_name localhost;

The line that modifies index is changed to:

index index.php index.html index.htm;

Remove the comments below to support php scripts:

location ~ \.php$ {
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME /var/www/nginx-default$fastcgi_script_name;
    include /etc/nginx/fastcgi_params;
}

Restart nginx:

/etc/init.d/nginx stop
/etc/init.d/nginx start

Start fastcgi php:

sudo /usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid

6. Install memcached server

sudo apt-get install memcached

Start the memcached service

memcached -d -m 128 -p 11111 -u root

Parameter description:

-p 监听的端口
-l 连接的IP地址, 默认是本机
-d start 启动memcached服务
-d restart 重起memcached服务
-d stop|shutdown 关闭正在运行的memcached服务
-d install 安装memcached服务
-d uninstall 卸载memcached服务
-u 以的身份运行 (仅在以root运行的时候有效)
-m 最大内存使用，单位MB。默认64MB
-M 内存耗尽时返回错误，而不是删除项
-c 最大同时连接数，默认是1024
-f 块大小增长因子，默认是1.25-n 最小分配空间，key+value+flags默认是48
-h 显示帮助

Check whether the service is started

ps aux | grep memcached

7, install memcached php extension

sudo apt-get install php5-memcached

After the installation is completed, nginx and fcgi need to be restarted to make memcached take effect.
