Systemd Zookeeper 服務失敗

Question

我創建了以下 systemd 服務腳本來使用 Ansible 運行 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，在嘗試使用sudo service zookeeper start運行腳本時，出現以下錯誤：

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
--

任何關於為什么我無法正確啟動 Zookeeper 的提示，因為我對系統服務很陌生？

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 用於權限要求

Answer 2

這聽起來像是首先要檢查的基礎知識，請確保文件存在

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

如果它沒有找到您提取 zookeeper 啟動腳本的位置。 在我的實例中，它是/opt/kafka/bin/zookeeper-server-start.sh

然后驗證您指定的用戶（您指定了兩個用戶， root和zookeeper 。我假設最后一個值是有效/所需的）可以訪問腳本並對其具有可執行權限。

這將分別使用chown和chmod命令完成。

Answer 3

也許太晚了……但用作 ExecStart：

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