运行brew list服务时查找Brew错误256（对于mariadb）的原因

Question

在我的 Mac 上，当我写：

sudo brew services list

时，我得到这个结果：

Name    Status     User File
------------------------------
dnsmasq started    root /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist
mariadb error  256 root /Library/LaunchDaemons/homebrew.mxcl.mariadb.plist
nginx   started    root /Library/LaunchDaemons/homebrew.mxcl.nginx.plist
[email protected] started    root /Library/LaunchDaemons/[email protected]

昨天我正在解决一个问题，我得到了这个结果：

Name    Status     User File
------------------------------
dnsmasq error  512 root ~/Library/LaunchAgents/homebrew.mxcl.dnsmasq.plist
mariadb started    root ~/Library/LaunchAgents/homebrew.mxcl.mariadb.plist
nginx   error  256 root ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist
[email protected] started    root ~/Library/LaunchAgents/[email protected]

问题1：

256

和

512

是什么意思？

问题2： 在哪里可以找到错误描述？

---

解决方案尝试 1：检查

/usr/local/var/log

我尝试这样做：

tail -f **/*.log

但我没有发现任何有用的东西。

---

解决方案尝试2：重启服务后搜索最新修改

我尝试重新启动服务：

sudo brew services restart mariadb

...然后列出最新修改的文件，如下所示：

find . -cmin -15

但这没有列出任何内容。

---

解决方案尝试3：获取信息：

sudo brew services info mariadb

使用该命令我只得到以下输出：

mariadb (homebrew.mxcl.mariadb)
Running: ✘
Loaded: ✔
Schedulable: ✘

但是对于这个

256

错误没有任何帮助。

---

解决方案尝试 4：将

-d

标志添加到

brew services

感谢 Luuk 添加

-d

（调试标志）的建议。

当我运行：

sudo brew services -d list

时，它会输出：

解决方案尝试5：重启时添加调试标志

mariadb

如果我这样做：

sudo brew services restart mariadb -d

然后它输出：

/usr/local/Homebrew/Library/Homebrew/brew.rb (Formulary::FormulaLoader): loading /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/mariadb.rb
Stopping `mariadb`... (might take a while)
==> Successfully stopped `mariadb` (label: homebrew.mxcl.mariadb)

Warning: mariadb must be run as non-root to start at user login!
==> Successfully started `mariadb` (label: homebrew.mxcl.mariadb)

与“非

-d

”版本相比，唯一的不同是省略了第一行，没有调试标志。

但是此后错误仍然存在。更奇怪的是，即使存在此错误，Mariadb 仍在工作：我正在本地开发环境中工作，我正在其中对 MariaDB 和所有内容进行更改。

Answer 1

在我的情况下，如果以 root 身份启动，服务甚至都不会在有或没有 -d 标志的情况下运行。

我排除故障的方式，问题是尝试以 root 身份运行 mariadb

> sudo mariadb

你会看到的

....
....
....
mariadbd: Please consult the Knowledge Base to find out how to run mysqld as root!

编辑/usr/local/etc/my.cnf，添加以下内容

[server]
user=your_username

现在以 root 身份启动服务，带或不带 -d 标志。

> sudo brew services start mariadb

您不应该看到错误 256。或者您可以在 homebrew.mxcl.mariadb.plist 中添加选项 --user=your_username

sudo brew services info mariadb
mariadb (homebrew.mxcl.mariadb)
Running: ✔
Loaded: ✔
Schedulable: ✘
User: root
PID: ?????

Answer 2

我刚刚升级到 Ventura，运行

brew upgrade

并出现错误 256。事实证明 mariadb 无法写入错误日志。在

/usr/local/etc/my.cnf

中写道：

# run "sudo touch /var/log/mariadb-err.log; sudo chmod 766 /var/log/mariadb-err.log" so the server can write to the log.

所以我这样做了并且可以再次连接。
