php-fpm 配置不当 导致 nginx 502 错误一例

​不要总看nginx 的日志文件。

 

cat /home/php/logs/php-fpm.log 部分内容如下

 

"Error: Wrong IP address ' 10.11.80.49' in listen.allowed_clients"

"Error: Connection disallowed: IP address '10.11.80.49' has been dropped."

 

ERROR: Connection disallowed: IP address "10.11.80.49" has been dropped

 

回头且看php-fpm 配置文件

cat /home/php/etc/php-fpm.conf 

 

[global]

pid = /home/php/logs/php-fpm.pid

error_log = /home/php/logs/php-fpm.log

log_level = notice

 

[www]

listen = 10.11.80.49:9000

listen.allowed_clients = 10.11.80.47,10.11.80.48, 10.11.80.49

user = nobody

group = nobody

 

slowlog = /home/php/logs/slow.log

catch_workers_output = yes

request_terminate_timeout = 30s

request_slowlog_timeout = 5s

 

pm = dynamic

pm.max_children = 100

pm.start_servers = 50

pm.min_spare_servers = 5

pm.max_spare_servers = 100

 

就是这里

 

[www]

listen = 10.11.80.49:9000

listen.allowed_clients = 10.11.80.47,10.11.80.48, 10.11.80.49

user = nobody

group = nobody

 

netstat 看到的端口是listen 状态，启动php-fpm 无报错。

其它两台机器 47 48 也没有问题，我就奇怪了，telnet 一下测试

 

#telnet 10.11.80.49 9000

Tring 10.11.80.49 ...

Connected to 10.11.80.49

Esape character is '^]'.

 

我分别在47 和48 上测试， 发现不一样的就是 49 是被直接close 掉的。

后面再看配置文件，48 后面多了一个空格。去掉重启，测试，我勒个去。
