在升级了php7.3.2版本之后，重新启动php-fpm过程中遇到一个报错。
An another FPM instance seems to already listen on /tmp/php-cgi.sock netstat -ant | grep 9000 //查看启动进程，发现没启动成功
我们去查看一下php-fpm.conf里面的配置：
vim /usr/local/php/etc/php-fpm.conf [www] listen = /tmp/php-cgi.sock //注意 listen.backlog = -1 listen.allowed_clients = 127.0.0.1 listen.owner = www listen.group = www
此时我们需要根据配置文件的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; }
修改完平滑重启nginx，然后启动php-fpm，OK
