yjiang's cake

今天心血来潮，再折腾一次.转换LAMP为LNMP

安装nginx+php5-cgi+spawn-fcgi

sudo aptitude purge apache2
sudo aptitude install nginx php5-cgi spawn-fcgi
#php5-cgi:安装完成后,默认运行在9000端口

配置nginx虚拟主机

cd /etc/nginx/site-available/default 
sudo cp default yjiang
cd ../site-enabled/
sudo ln -s ../site-available/yjiang ./
sudo vi yjiang

配置文件修改如下:

server {
    listen  80;
    server_name yjiang.tk;            #绑定域名
    root /var/www/cake;                     #网站根目录
    index index.htm index.html index.php;   #默认文件
    #include /var/www/cake/.htaccess        #引用.htaccess
    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        #fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
        include /etc/nginx/fastcgi_params;  #fastcig_params参数文件地址
    }
    location ~ .*\.(png|jpg|gif|js|css)${
        expires 10d;
    }
    access_log  /var/log/nginx/access_cake.log;
    error_log  /var/log/nginx/error_cake.log;
}

使用spawn-fcgi管理php5-cgi

killall php5-cgi 

/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 6 -u www-data -g www-data -f /usr/bin/php5-cgi 
#参数说明: -P 端口  -C 使用的进程数 -u 用户 -g 组     

• 默认是不支持rewrite的写法，.htaccess文件也需要include进去
• 实际运行中,spawn-fcgi曾挂掉过多次,而换用php5-cgi以来,已正常运行超过3个月.所以还是推荐使用php5-cgi,而只用spawn-fcgi来管理php5-cgi.
