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我得到这个结果：

\n

Name    Status     User File\n------------------------------\ndnsmasq started    root /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist\nmariadb error  256 root /Library/LaunchDaemons/homebrew.mxcl.mariadb.plist\nnginx   started    root /Library/LaunchDaemons/homebrew.mxcl.nginx.plist\nphp@7.4 started    root /Library/LaunchDaemons/homebrew.mxcl.php@7.4.plist\n

\n

昨天我正在解决一个问题，我得到了这个结果：

\n

Name    Status     User File\n------------------------------\ndnsmasq error  512 root ~/Library/LaunchAgents/homebrew.mxcl.dnsmasq.plist\nmariadb started    root ~/Library/LaunchAgents/homebrew.mxcl.mariadb.plist\nnginx   error  256 root ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist\nphp@7.4 started    root ~/Library/LaunchAgents/homebrew.mxcl.php@7.4.plist\n

\n

问题1：256和是什么512意思？

\n

问题2：在哪里可以找到错误描述？

\n

\n

解决方案尝试 1：检查/usr/local/var/log

\n

我尝试这样做：

\n

tail -f **/*.log\n

\n

但我没有发现任何有用的东西。

\n

---

\n

解决方案尝试2：重启服务后搜索最新修改

\n

我尝试重新启动服务：sudo brew services restart mariadb

\n

...然后列出最新修改的文​​件，如下所示：

\n

find . -cmin -15\n

\n

但这什么也没列出。

\n

---

\n

解决方案尝试 3：获取信息：sudo brew services info mariadb

\n

使用该命令我只得到以下输出：

\n

mariadb (homebrew.mxcl.mariadb)\nRunning: \xe2\x9c\x98\nLoaded: \xe2\x9c\x94\nSchedulable: \xe2\x9c\x98\n

\n

但对于这个256错误没有任何帮助。

\n

\n

解决方案尝试 4：添加-d标志brew services

\n

感谢 Luuk 添加（调试标志）的建议-d。

\n

当我运行 :sudo brew services -d list时，它会输出：

解决方案尝试 5：重新启动时添加调试标志mariadb

\n

如果我这样做：sudo brew services restart mariadb -d

\n

然后它输出：

\n

/usr/local/Homebrew/Library/Homebrew/brew.rb (Formulary::FormulaLoader): loading /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/mariadb.rb\nStopping `mariadb`... (might take a while)\n==> Successfully stopped `mariadb` (label: homebrew.mxcl.mariadb)\nWarning: Taking root:admin ownership of some mariadb paths:\n  /usr/local/Cellar/mariadb/10.7.3/bin\n  /usr/local/Cellar/mariadb/10.7.3/bin/mariadbd-safe\n  /usr/local/opt/mariadb\n  /usr/local/opt/mariadb/bin\n  /usr/local/var/homebrew/linked/mariadb\nThis will require manual removal of these paths using `sudo rm` on\nbrew upgrade/reinstall/uninstall.\nWarning: mariadb must be run as non-root to start at user login!\n==> Successfully started `mariadb` (label: homebrew.mxcl.mariadb)\n

\n

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。

\n

但此后错误仍然存​​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。

\n

Answer 1

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

\n

我排除故障的方式，问题是尝试以 root 身份运行 mariadb

\n

> sudo mariadb\n

\n

你会看到

\n

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

\n

编辑/usr/local/etc/my.cnf，添加以下内容

\n

[server]\nuser=your_username\n

\n

现在以 root 身份启动服务，带或不带 -d 标志。

\n

> sudo brew services start mariadb\n

\n

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

\n

sudo brew services info mariadb\nmariadb (homebrew.mxcl.mariadb)\nRunning: \xe2\x9c\x94\nLoaded: \xe2\x9c\x94\nSchedulable: \xe2\x9c\x98\nUser: root\nPID: ?????\n
