使用spawn-fcgi运行php-cgi

install

sudo apt-get install spawn-fcgi

php启动脚本

一种是使用端口号。

 /usr/local/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -u ${user} -g ${group} -f /usr/bin/php5-cgi -C 128

一种是使用sock文件。

 /usr/local/bin/spawn-fcgi -u ${user} -g ${group} -s /tmp/php.sock -f /usr/bin/php5-cgi -P ${pidpath} 1>/dev/null

附nginx关于php-cgi配置

当spawn-fcgi开启两个端口，利用nginx的upstream负载均衡php程序到不同的fcgi端口上。

upstream  spawn {
    # 负载策略: ip_hash;
    server 127.0.0.1:9000 max_fails=0 fail_timeout=30s;
    server 127.0.0.1:9001 max_fails=0 fail_timeout=30s;
}

location ~ .php$ {
    fastcgi_pass   spawn;
    fastcgi_index  index.php;

    fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
    fastcgi_param  QUERY_STRING     $query_string;
    fastcgi_param  REQUEST_METHOD   $request_method;
    fastcgi_param  CONTENT_TYPE     $content_type;
    fastcgi_param  CONTENT_LENGTH   $content_length;
}

附运行spawn-fcgi脚本二种

#!/bin/bash
PHP_SCRIPT="/usr/local/bin/spawn-fcgi -a 127.0.0.1 -p 2222 -u www-data -g www-data -f /usr/bin/php5-cgi -C 128"
FASTCGI_USER=www-data
RETVAL=0
case "$1" in
    start)
        su - $FASTCGI_USER -c "$PHP_SCRIPT"
        RETVAL=$?
        ;;
    stop)
        killall -9 php5-cgi
        RETVAL=$?
        ;;
    restart)
        killall -9 php5-cgi
        su - $FASTCGI_USER -c "$PHP_SCRIPT"
        RETVAL=$?
        ;;
    *)
        echo "Usage: php {start|stop|restart}"
        exit 1
        ;;
esac
exit $RETVAL
