Java environment variable configuration under Mac

Found a pit: Recently found a colleague in accordance with this method to configure the JDK environment variable has been unsuccessful, later found that he was using "oh-my-zsh", the path of the profile is not/etc/profile or ~/.bash_profile, it has its own configuration file, So it is recommended that you use the Mac comes with the terminal or ITerm2 to configure.

#临时提权

sudo su

#输入密码

Vi/etc/profile

#配置JAVA_HOME, where the path is filled out according to your own version

Java_home= "/system/library/java/javavirtualmachines/1.6.0.jdk/contents/home/"

Class_path= "$JAVA _home/lib"

#把JAVA添加到到环境变量PATH中

Path= ".: $PATH: $JAVA _home/bin"

#设置tomcat的主目录

#CATALINA_HOME = "/usr/local/tomcat" (Tomcat must be installed in advance)

#将JAVA_HOME和CATALINA_HOME设置为环境变量

#export Java_home Catalina_home

Export Java_home
