Systemd Zookeeper服务失败

Question

我已经创建了以下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sudo service zookeeper start运行脚本时，我得到了以下错误：

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
--

为什么我不能正确启动Zookeeper，因为我对系统服务还很陌生？

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表示权限要求

Answer 2

这听起来像是基本的检查，首先要确保文件存在

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

如果它找不到您解压zookeeper启动脚本的位置。在我的实例中，它是/opt/kafka/bin/zookeeper-server-start.sh

然后验证您指定的用户(您已经指定了两个用户，root和zookeeper。我假设最后一个值是有效的/期望的)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。

也许这么晚了..。但用作ExecStart：

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