我有以感叹号开头的目录,如:

!test

我想在gitignore中添加它,但这似乎不起作用:

\!test

这样做的正确方法是什么？

我有一些元素，例如 A 类

<a class="A">test</a>

然后我尝试从元素中删除该类：

$('.A').removeClass('.A');

但它似乎不起作用，如果我只知道这个元素的一个类，如何使它起作用？

部署新版应用程序时出现问题:超时错误,应用程序未更新(但应用程序仍在运行)

我有一个想法,检查服务器上的amazon工具是否正常工作.为了实现这一点,我需要启动新实例并终止旧(因此它将没有停机时间)

什么是最好的方式替换实例没有停机？

PS超时是最大值(30分钟,日志中的实例根本没有关于新部署的信息)

在跑步的时候

npm run dev

我突然开始出错，几乎没有对项目代码进行任何更改：

修改应用程序的代码使其不包含任何文件或加载任何内容仍然会产生相同的错误。

启动 mysqlbinlog 时返回错误：

root@utils # mysqlbinlog --start-datetime="2021-12-05 13:13:00"
mysqlbinlog: unknown variable 'default-character-set=utf8mb4'

如何修复它？

也许，它与 /etc/mysql/mariadb.conf.d/50-client.cnf 的内容有关，即：

[client]
# Default is Latin1, if you need UTF-8 set this (also in server section)
default-character-set = utf8mb4

# socket location
socket = /var/run/mysqld/mysqld.sock

# Example of client certificate usage
# ssl-cert=/etc/mysql/client-cert.pem
# ssl-key=/etc/mysql/client-key.pem
#
# Allow only TLS encrypted connections
# ssl-verify-server-cert=on

# This group is *never* read by mysql client library, though this
# /etc/mysql/mariadb.cnf.d/client.cnf file is not read by Oracle MySQL …
