宝塔环境下云锁Nginx模块自编译错误解决：[alert] 15589#0: worker process 17580 exited on signal 6

云锁界面中如果没有自编译Nginx的话，上图自编译那里是灰色不可用的：则web防护不生效，但是系统防护是生效的。

也就意味着大部分功能是无法使用的，比如防CC，防SQL注入，防盗链，防端口扫描…等功能无法生效。

PS：Nginx自编译的教程有很多，这里是微凉写的参考教程：宝塔+云锁nginx自编译web防护

和大半年来的几次一样，虽然按上边教程自编译成功了，但是宝塔的Nginx里生成了大量错误日志，如果不能解决，用不多久服务器就扛不住了，错误日志都是下边这样的：

2022/03/29 13:28:50 [alert] 15589#0: worker process 17526 exited on signal 6
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
2022/03/29 13:29:19 [alert] 15589#0: worker process 17619 exited on signal 6

what(): std::bad_alloc
2022/03/29 13:29:22 [alert] 15589#0: worker process 17628 exited on signal 6

2022/03/29 13:30:08 [alert] 15589#0: worker process 17614 exited on signal 6

what(): std::bad_alloc
2022/03/29 13:30:12 [alert] 15589#0: worker process 17580 exited on signal 6

在宝塔面板中找到服务器agent端 /usr/local/yunsuo_agent/FilterKernel.xml （vi修改）

注释掉一行代码，然后替换回去即可：

原始代码：

<?xml version='1.0' encoding='utf-8'?>

修改后代码：

<Framework product_type="yunsuo" retcode="404">
<!--PlugIn dllpath="libs/libbypass.so" RunOn_Filter=".*" RunOn_Product=".*"/-->

最后重启下Nginx和Php，终于没有新的错误日志生成了！

PS：如果正常编译后启动Nginx出现如下错误：

Nginx配置规则错误:

nginx: the configuration file /www/server/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /www/server/nginx/conf/nginx.conf test failed

原因应该是之前有安装过宝塔的付费插件过期未付费导致的，重新续费或卸载后Nginx即可正常启动。
