Question

我在安装后正确启动tomcat服务时遇到问题。我正在使用centos 7 bash 4。

如果 tomcat用户和 tomcat服务名称相同，我的脚本工作正常，并在最后得到服务pid，但如果它们不同那么出错了，服务无法正常运行，也没有服务pid。

这是我正在使用的脚本。

谁能告诉我这场冲突可能是什么原因？

谢谢。

Answer 1

理解你的代码的关键是这个命令：

tomcat_pid() {
    echo `ps aux | ps -ef | grep $TOMCAT_SVC | grep java | awk ' { print $2 } '`
}

应该/可能是：

tomcat_pid() {
    echo `ps aux | ps -ef | grep $tomcatDirName | grep java | awk ' { print $2 } '`
}

<强>解释

ps命令列出所有正在运行的进程（包括其路径），而grep根据您的“关键字”过滤该列表（在您当前的代码中，它是$ TOMCAT_SVC / tomcatSvc）。

看看你的“工作tomcat ps aux结果”，我可以看到应用程序是在tomcat802文件夹中启动的。此外，路径中没有任何名为“tomcatSvc”的内容：

502 687 1 3月31日？ 1-17：06：35 /opt/pilot/java/jdk1.8.0_45/bin/java -Djava.util.logging.config.file = /选择/导频/ tomcat802 / CONF / logging.properties -Djava.util.logging.manager = org.apache.juli ...

因此，如果你保留原始命令，系统将找不到正确的PID（因为你的可执行路径中没有文字“tomcatsvc”）如果您更改为我推荐的命令，系统将找到它。

警告：这种查找PID的方式很危险，因为如果你有另一个运行程序，其路径包含“tomcat802”，则可以选择该程序。你想把绝对路径而不是tomcat802;并确保没有人移动该文件夹，否则代码可能会中断。

使用bash在centos上安装tomcat和java
