如果 url/file 不存在，nginx 提供与本地服务器不同的文件名

1

如果文件不存在，有没有办法app-*.js在其他文件夹中服务器另一个文件，例如：

转到网址：http ://www.example.com/assets/build/app/app-48fee50a26.js

我收到以下错误消息：

[error] 17788#17788: *1 open() "/var/app/assets/build/app/app-48fee50a26.js" failed (2: No such file or directory), client: , server: , request: "GET /assets/build/app/app-48fee50a26.js HTTP/1.1", host:""

我想在同一文件夹中提供任何其他 js 文件/var/app/assets/build/app/，但其他文件的名称可以不断更改，例如app-62a5962b0a11.js. 我在想app\-(.*)\.js。

以下所有示例均无效：

server {
        listen 80 default_server;
        root /var/app;

        location /assets/build/app/app\-(.*)\.js {
                try_files $uri $uri/ /assets/build/app/app\-(.*)\.js;
        }
}

server {
        listen 80 default_server;
        root /var/app;

        location /assets/build/app/app\-(.*)\.js {
                try_files $uri $uri/ /var/app/assets/build/app/app\-(.*)\.js;
        }
}


Also not working without regex to the location of the other file.

server {
        listen 80 default_server;
        root /var/app;

        location /assets/build/app/app\-(.*)\.js {
                try_files $uri $uri/ /var/app/assets/build/app/app-62a5962b0a11.js;
        }
}

server {
        listen 80 default_server;
        root /var/app;

        location /assets/build/app/app\-(.*)\.js {
                try_files $uri $uri/ /assets/build/app/app-62a5962b0a11.js;
        }
}

检查单个 PHP-FPM 进程的平均内存使用情况

2

我尝试了以下命令来检查单个 PHP-FPM 进程的平均内存使用情况

ps --no-headers -o "rss,cmd" -C php-fpm | awk '{ sum+=$1 } END { printf ("%d%s\n", sum/NR/1024,"M") }'

我得到了一个错误awk: cmd. line:1: fatal: division by zero attempted

而这个命令

total=0; for i in `ps -C php-fpm -o rss=`; do total=$(($total+$i)); done; echo "Memory usage: $total kb";
Memory usage: 0 kb

ps -ef | grep php
root       9435      1  0 11:42 ?        00:00:00 php-fpm: master process (/etc/php/7.0/fpm/php-fpm.conf)

systemd 的 mysqld.service - 无法解析资源值，忽略：40000 - LimitMEMLOCK

当我为 MYSQL 5.7mysql systemd[1]: [/usr/lib/systemd/system/mysqld.service:39] Failed to parse resource value, ignoring: 40000设置限制时，我在使用 mysql 5.7 的 Centos 7 上遇到了这个错误。LimitMEMLOCK

LimitMEMLOCK=40000

为什么不能为设置数字限制LimitMEMLOCK？
目的是LimitMEMLOCK什么？
是唯一的灵魂LimitMEMLOCK=infinity吗？
