tomcat報錯catalina.sh: line 401: /usr/java/jdk1.7.52/bin/java: No such file or directory

將生產服務器的Tomcat目錄打包過來后解壓后，啟動Tomcat后，發現如下問題：


# ./shutdown.sh 
Using CATALINA_BASE:   /usr/local/tomcat 
Using CATALINA_HOME:   /usr/local/tomcat 
Using CATALINA_TMPDIR: /usr/local/tomcat/temp 
Using JRE_HOME:       /usr/java/jdk1.7.52
/usr/local/tomcat/bin/catalina.sh: line 401: /usr/java/jdk1.7.52/bin/java: No such file or directory




其實安裝的是jdk-8u102-linux-x64.rpm，其實並沒有所謂的/usr/java/dk1.7.52目錄，而是/usr/java/jdk1.8.0_102/


發現/etc/profile文件下的jar_home指向錯誤，
於是修改vim /etc/profile


export JAVA_HOME=/usr/java/jdk1.8.0_102/
export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export SANP_HOME=/home/aaa


使配置生效，重新啟動tomcat即可
source /etc/profile
