Question

CentOS7.2
Tomcat9
JDK8

我已经在我的evn中设置JAVA_HOME并在cammand行中运行catalina.sh run，tomcat开始成功。但我使用systemctl start tomcat.service我收到错误。

11月 04 22:13:02 iZwz90squb7zj67pw5hyizZ systemd[1]: Starting tomcat...
11月 04 22:13:02 iZwz90squb7zj67pw5hyizZ startup.sh[1058]: Neither the     JAVA_HOME nor the JRE_HOME environment variable is defined
11月 04 22:13:02 iZwz90squb7zj67pw5hyizZ startup.sh[1058]: At least one of these environment variable is needed to run this program
11月 04 22:13:02 iZwz90squb7zj67pw5hyizZ systemd[1]: tomcat.service: main process exited, code=exited, status=1/FAILURE
11月 04 22:13:02 iZwz90squb7zj67pw5hyizZ systemd[1]: Failed to start tomcat.
11月 04 22:13:02 iZwz90squb7zj67pw5hyizZ systemd[1]: Unit tomcat.service entered failed state.
11月 04 22:13:02 iZwz90squb7zj67pw5hyizZ systemd[1]: tomcat.service failed.

这是我的tomcat.service。

Answer 1

在JAVA_HOME文件的JRE_HOME部分添加Service或tomcat.service环境变量。

Systemd不会使用shell实例的环境变量，因此您需要将它们添加到配置中。

例如：

[Unit]
Description=tomcat
After=network.target

[Service]
Type=oneshot
Environment=JAVA_HOME=/path/to/jre
Environment=CATALINA_PID=/var/run/tomcat.pid
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
ExecStart=/usr/local/tomcat/bin/startup.sh
ExecStop=/usr/local/tomcat/bin/shutdown.sh
ExecReload=/usr/bin/kill -s HUP $MAINPID
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

您需要运行systemctl daemon-reload以加载服务文件的更新。您可以使用systemctl cat tomcat.service验证单元文件是否已进行更改。

Tomcat无法从centos7.2上的systemctl开始
