解决Openfire 打不开问题

打开openfire 需要配置java坏境，下载地址http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
如果还是打不开，打开终端执行以下命令

①：sudo chmod -R 777 /usr/local/openfire/bin
②：sudo su
③：cd /usr/local/openfire/bin
④：export JAVA_HOME=`/usr/libexec/java_home`
⑤：echo $JAVA_HOME /Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home
⑥: cd /usr/local/openfire/bin
⑦: ./openfire.sh

如果提示

这还是打不开的，意思就是说你的java 必须是8.0以上的，我之前的是java 1.6.0的jdk，到我提供的下载地址去下载即可，下载完以后还需要删除原来的jdk，查看文件/Library/Java/JavaVirtualMachines/有2个jdk，删除其余的，保留 1.8.0 那个就行
这时候在到偏好设置里打开openfire 就可以打开了
