php-fpm开启报错-ERROR: An another FPM instance seems..

netstat -ant | grep 9000  //查看启动进程，发现没启动成功

查看php-fpm.conf里面的配置：

vim  /usr/local/php/etc/php-fpm.conf

[www]
listen = /tmp/php-cgi.sock   //注意这里,要与下面的一致
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www

此时根据配置文件的listen地址做对应的修改：

vim /usr/local/nginx/conf/nginx.conf

location ~ [^/]\.php(/|$) {
       fastcgi_pass unix:/tmp/php-cgi.sock;    //把127.0.0.1:9000改为此行
       fastcgi_index index.php;
       fastcgi_param SCRIPT_FILENAME     $document_root$fastcgi_script_name;
       include fastcgi_params;
}
location / {
      root   html;
      index index.php index.html index.htm;
}

修改完后重启nginx，然后启动php-fpm就恢复正常了.
