我在以下位置定义了 mariadb 的服务： /etc/systemd/system/mariadb.service
[Unit]
Description=start and stop MySQL(MariaDB) Server
After=syslog.target
After=network.target
[Service]
Type=simple
User=Umariadb
Group=Gmariadb
# Restart=always
# PermissionsStartOnly=true
ExecStart=/usr/local/ServerWeb/mariadb/bin/mysqld_safe --user=mysql --ledir=/usr/local/ServerWeb/mariadb/bin --datadir=/usr/local/ServerWeb/mariadb/data
# ExecStop=/usr/bin/vgaoff stop
TimeoutSec=300
PrivateTmp=true
[Install]
WantedBy=multi-user.target
后来我激活了它：
systemctl enable mariadb.service
现在，重新启动后，服务没有开始。
然后我需要再次禁用该服务。
当尝试再次手动执行时，它工作得很好......
sudo /usr/local/ServerWeb/mariadb/bin/mysqld_safe --user=mysql --ledir=/usr/local/ServerWeb/mariadb/bin --datadir=/usr/local/ServerWeb/mariadb/data
我的服务脚本定义得好吗？
我想知道问题是什么。怎么解决呢？

答案1
不使用mysqld_safe。
你会遇到各种各样的问题，归根结底都是为了打造一个竞争者，在这个领域占据一席之地。systemd 恐怖屋通过在服务管理下运行一个Poor Man's Dæmon Supervisor（在shell脚本中写得很糟糕）。您可以费力地检查和调整事物，以便它们更好地互操作，处理准备协议不匹配以及最终在两个不同的地方以两种不同的方式设置事物的冲突，但这确实毫无意义。相反，向 daemontools 世界学习，它想要mysqld_safe 消失了自世纪之交以来。
这么多年过去了，您也可以在 systemd 世界中摆脱它。 MariaDB 世界有一个区别，与 Oracle 和 MySQL 世界形成鲜明对比，它实际上提供了关于如何以 daemontools/runit/s6 用户多年来一直想要的方式运行 MariaDB 的良好文档，而不是mysqld_safe使用该服务用于服务管理的管理工具集。
玛丽亚数据库附带mariadb.servicesystemd 的服务单元，以及将mariadb-service-convert设置迁移my.cnf到 systemd 服务单元设置的工具。它甚至附带了一个[email protected]服务单元模板，允许用户将多个服务器作为不同的服务运行。使用那些。

我的安装过程是（在询问之前）
sudo tar zxvf /media/sf_Users/josebernal/Downloads/Php\ Tomcat\ Httpd\ MySQL/mariadb-10.1.20-linux-x86_64.tar.gz -C /usr/local/
