SystemD memcached 服务 - (code=exited, status=1/FAILURE)

  • 772

所以我不得不在 /var/run/memcached 中使用 SOCKET 部署 Rocky Linux 8 memcached

为了避免服务失败，我运行了以下命令：

  • systemctl 编辑 memcached.service

粘贴在：

[Unit]
Description=Memcached
Before=httpd.service
After=network.target
[Service]
Type=simple
User=memcached
Group=memcached
# Run ExecStartPre with root-permissions
ExecStartPre=-/usr/bin/mkdir /var/run/memcached
ExecStartPre=-/usr/bin/chown -R memcached:memcached /var/run/memcached/
[Install]
WantedBy=multi-user.target

[root@cp monit.d]# service memcached status

有什么方法可以避免这种失败？

ExecStartPre=/usr/bin/mkdir /var/run/memcached (code=exited, status=1/FAILURE)

谢谢！

    您现在正在做的事情——/var/run/memcached通过创建ExecStartPre——很好，但处理这个问题的规范方法是通过systemd-tmpfiles服务。您/etc/tmpfiles.d/memcache.conf使用以下内容创建：

    D /run/memcached 0700 memcached memcached

    这将在系统启动时创建目录/run/memcached（通常/var/run只是一个符号链接）。/run这意味着您不需要处理在服务单元中创建目录。

    另请参阅或 中的tmpfiles.d手册页和现有配置文件。/etc/tmpfiles.d/usr/lib/tmpfiles.d
