plesk VPS 问题托管 magento 的问题。 /tmp 中的#sql_1ed7_0.MYD 关闭服务器答案

【问题标题】：Trouble with plesk VPS issue hosting magento. #sql_1ed7_0.MYD in /tmp brings down serverplesk VPS 问题托管 magento 的问题。 /tmp 中的#sql_1ed7_0.MYD 关闭服务器
【发布时间】：2023-03-12 00:57:01
【问题描述】：

希望有人可以提供帮助！我不断在 /tmp 中创建这些文件，这在尝试访问 Web 甚至 plesk 面板时会在下面创建错误，直到我通过 SSH 或 FTP 进入并手动删除它（#sql_1ed7_0.MYD）：

ERROR: Zend_Db_Statement_Exception: SQLSTATE[HY000]: General error: 1 Can't create/write to file '/tmp/#sql_1ed7_0.MYD' (Errcode: 17) (Pdo.php:234)

任何 MySQL 日志中都没有任何内容，将 my.cnf 中的 mysql tmp 目录更改为 home/mysqltmp 并且仍然发生，所以看起来不是问题所在。我认为它可能与 httpd.conf 有关，这是 apache error_log 中发生的日志：

完全不知所措....谷歌无处可去:(刚刚在magento中安装了一个完整的页面缓存模块，我认为这是日志中缓存文件错误的来源，但在此问题开始后安装。

不想一直照看服务器以一次又一次地删除此文件。

值得注意的是，/tmp 目录 (1777) 的权限没有问题，但是创建的文件具有 644 的权限，一旦我删除它，一切都会备份。

【问题讨论】：

您的服务器上有可用的硬盘空间吗？
是的，只需查看 plesk 43gb 免费的服务器信息。 Cpu 最后 15 分钟坐在 3.23 和 ram 15.1%
这条消息“系统中打开的文件太多”应该是问题的原因......我发现了这个：forum.sp.parallels.com/threads/…

标签： mysql apache magento plesk server

【解决方案1】：

似乎 Magento 没有什么问题。您的 apache 日志说：系统中打开的文件太多。

您需要增加允许打开的文件描述符的最大数量。为此，请找到 Apache 初始化脚本并在其中添加下一行：

ulimit -n 65536

通常，Apache 初始化脚本放在 /etc/init.d/apache2 或 /etc/init.d/httpd 路径中。

结果如下：

#!/bin/sh
### BEGIN INIT INFO
# Provides: apache2
# Required-Start: $local_fs $remote_fs $network $syslog $named
# Required-Stop: $local_fs $remote_fs $network $syslog $named
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# X-Interactive: true
# Short-Description: Start/stop apache2 web server ### END INIT INFO
set -e
ulimit -n 65536

之后重启 Apache：

/etc/init.d/apache2 restart

【讨论】：

你认为这会导致他的临时文件被创建然后搞砸了吗？需要进一步回到日志中，因为我认为在安装完整页面缓存模块之后发生了很多文件，这是在这个问题在本周开始之后开始的，所以可能完全是一个单独的问题
我认为mysql无法写入创建的文件，因为它应该打开文件进行写入但由于文件限制而无法执行。 “系统中打开的文件太多”是第一个应该解决的问题，因为这是服务器级别的问题，许多服务可能工作不稳定或根本无法工作，并在日志中产生奇怪和混乱的消息。
是的，magento 有一个很好的填充日志的习惯。无限值的安全限制是多少？
65536 应该没问题。我在我的服务器上使用它。也请看看这个提示：dev.mysql.com/doc/refman/5.0/en/linux-postinstallation.html
完美，我会试试看效果如何！

【解决方案2】：

又发生了，记录文件创建的时间（很多）

【讨论】：

似乎服务器上启动了太多进程。例如，服务器上放置的站点过多（300-400 或更多）。每个站点都使用 Apache/PHP/MySQL 运行，它们有自己的日志文件等。您能否提供有关您的托管类型、CPU 和内存的更多详细信息？（你使用1und1.de 吗？:)
是的，它是 1and1，但在英国。该服务器有 3 个 CPU 内核到内存和 2GB 内存，4GB 可按需提供。仅托管这一个 magento 网站。
完美运行，直到滚动到新的 magento 模板！不明白为什么一个模板会占用这么多资源。新模板比以前慢了很多，这就是为什么必须继续整页缓存的原因
你能显示下一个命令的结果吗：cat /proc/user_beancounters
在下面发布为答案

【讨论】：

请看这个：kb.sp.parallels.com/en/1354 然后看你的失败计数列。如果它的值大于零，请更改 Virtuozzo (openVZ) 设置。
很难判断它返回的方式是哪一列失败。从它看起来像 failcnt 都是 0 除了 kmemsize 有 1626
我将如何检查/修改相关设置？
kmemsize=1626，tcpsndbuf=8896551。 kmemsize - 为特定 VE 进程的内部内核结构分配的不可交换内核内存的大小。 tcpsndbuf - TCP 套接字的发送缓冲区的总大小，即为从应用程序发送到 TCP 套接字但尚未得到远程端确认的数据分配的内核内存量。我不确定你可以访问这个 openVZ 设置，请询问托管支持（尝试检查 /etc/vz/vz.conf）。
这是一个需要增加的危险信号吗？
