FAQ​

openfire 安装完毕后无法登录控制台

报错：Login failed:make sure your username and password are correct and that you’re an admin or moderator

解决方案如下：
1.使用Mysql查看工具进入数据库，进入表“ofuser”，将该表清空，然后执行该SQL
INSERT INTO ofUser (username, plainPassword, name, email, creationDate, modificationDate)
    VALUES ('admin', 'admin', 'Administrator', '[email protected]', '0', '0');

2.关闭openfire服务，就是从其控制台stop然后再start，再用用户名：admin,密码：admin登录即可

openfire 进程无法启动

报错：nohup: failed to run command `/opt/openfire/jre/bin/java': No such file or directory

解决方案如下：
经检查是由于openfire未能正确识别jre环境变量导致，安装时自带的jre是32位，但操作系统却是64位操作平台。
，故在/etc/init.d/openfire的启动脚本修改，
JAVA_HOME="/usr/lib/jvm/jre-$VERSION.x86_64"
