linux - Systemd Zookeeper 服务失败

Question

我创建了以下 systemd 服务脚本，用于使用 Ansible 运行 Zookeeper：

[Unit]
Description=ZooKeeper

[Service]
User=root
Type=forking
User=zookeeper
Group=zookeeper
ExecStart=/tmp/zookeeper-3.4.9/bin/zkServer.sh start
ExecStop=/tmp/zookeeper-3.4.9/bin/zkServer.sh stop

TimeoutSec=300

[Install]
WantedBy=multi-user.target 

但是，在尝试使用运行脚本时sudo service zookeeper start，出现以下错误：

Nov 15 22:00:35 sharedservicesprovider systemd[1]: Starting ZooKeeper...
-- Subject: Unit zookeeper.service has begun start-up
-- Defined-By: systemd
-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel
--

由于我对系统服务很陌生，为什么我无法正确启动 Zookeeper 的任何提示？

Answer 1

[Unit]
Description=Zookeeper
After=syslog.target
[Service]
Environment=ZOO_LOG_DIR=/zookeeper/logs
SyslogIdentifier=zookeeper
TimoutStartSec=10min
Type=forking
User=zookeeper
Group=zookeeper
ExecStart=/zookeeper/bin/zkServer.sh start
ExecStop=/zookeeper/bin/zkServer.sh stop
[Install]
WantedBy=multi-user.target

ZOO_LOG_DIR 用于权限要求

Answer 2

也许这么晚了......但用作ExecStart：

/tmp/zookeeper-3.4.9/bin/zkServer.sh start-foreground

Answer 3

这听起来像是首先要检查给我的基础知识，确保文件存在

ls -ltrah /tmp/zookeeper-3.4.9/bin/zkServer.sh

如果它没有找到您提取 zookeeper 启动脚本的位置。在我的例子中，它是/opt/kafka/bin/zookeeper-server-start.sh

然后验证您指定的用户（您指定了两个用户root和zookeeper. 我假设最后一个值是有效/所需的）可以访问脚本并对其具有可执行权限。

这将分别使用chown和chmod命令来完成。
