如何在Centos中为Apache Tomcat设置JAVA_HOME？

Question

    E325: ATTENTION
    Found a swap file by the name "/etc/profile.d/.java.sh.swp"
              owned by: root   dated: Thu Oct 19 14:21:28 2017
             file name: /etc/profile.d/java.sh
              modified: YES
             user name: root   host name: rtp
            process ID: 31766
    While opening file "/etc/profile.d/java.sh"
    
    (1) Another program may be editing the same file.  If this is the case,
        be careful not to end up with two different instances of the same
        file when making changes.  Quit, or continue with caution.
    (2) An edit session for this file crashed.
        If this is the case, use ":recover" or "vim -r /etc/profile.d/java.sh"
        to recover the changes (see ":help recovery").
        If you did this already, delete the swap file "/etc/profile.d/.java.sh.swp"
        to avoid this message.
    
    Swap file "/etc/profile.d/.java.sh.swp" already exists!

    export JAVA_HOME=/usr/bin/java/java-1.8.0-openjdk.x86_64 
    export PATH=$PATH:$JAVA_HOME/bin
    export CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar

我又不明白该怎么办了。我已经重复了两天了。拜托，有什么帮忙吗？
