  • Linux下tomcat无法启动/启动后无法用过127.0.0.1:8080访问解决方案

    启动tomcat情况如下:

    root@ubuntu:/usr/local/tomcat/apache-tomcat-8.5.20/bin# ./catalina.sh
    Using CATALINA_BASE: /usr/local/tomcat/apache-tomcat-8.5.20
    Using CATALINA_HOME: /usr/local/tomcat/apache-tomcat-8.5.20
    Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-8.5.20/temp
    Using JRE_HOME: /usr/local/java/jdk1.8.0_144
    Using CLASSPATH: /usr/local/tomcat/apache-tomcat-8.5.20/bin/bootstrap.jar:/usr/local/tomcat/apache-tomcat-8.5.20/bin/tomcat-juli.jar
    Usage: catalina.sh ( commands ... )
    commands:
    debug Start Catalina in a debugger
    debug -security Debug Catalina with a security manager
    jpda start Start Catalina under JPDA debugger
    run Start Catalina in the current window
    run -security Start in the current window with security manager
    start Start Catalina in a separate window
    start -security Start in a separate window with security manager
    stop Stop Catalina, waiting up to 5 seconds for the process to end
    stop n Stop Catalina, waiting up to n seconds for the process to end
    stop -force Stop Catalina, wait up to 5 seconds and then use kill -KILL if still running
    stop n -force Stop Catalina, wait up to n seconds and then use kill -KILL if still running
    configtest Run a basic syntax check on server.xml - check exit code for result
    version What version of tomcat are you running?
    Note: Waiting for the process to end and use of the -force option require that $CATALINA_PID is defined

    在一个网站上看到说这个是因为环境变量的问题,tomcat使用的环境变量是自己的或者是继承自当前用户的,所以在Linux里面即使你设置了java_home也不一定会用这个,所以要么你都继承root的环境变量,都统一起来确保你的系统里面的环境变量都是使用的同一个,要么就单独指定要使用的jdk。tomcat启动的时候需要盗用setclasspath.sh。只要在setclasspath.sh声明环境变量就可以知道你这个tomcat使用哪个jdk,打开tomcat的bin目录下面的setclasspath.sh,添加上,路径自己修改,添加在开头就行

    export JAVA_HOME=/usr/local/java/jdk1.8.0_144
    export JRE_HOME=/usr/local/java/jdk1.8.0_144/jre

    然后重启tomcat就可以使用了

    这样可使配置不同的tomcat使用不同的jdk
