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

将生产服务器的Tomcat目录打包过来后解压后，启动Tomcat后，发现如下问题：





# ./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









其实安装的是jdk-8u102-linux-x64.rpm，其实并没有所谓的/usr/java/dk1.7.52目录，而是/usr/java/jdk1.8.0_102/





发现/etc/profile文件下的jar_home指向错误，

于是修改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，重新启动tomcat即可

source /etc/profile
