gerrit集成gitweb：Error injecting constructor, java.io.IOException: Permission denied

使用gerrit账户在centos上安装gerrit，然后集成gitweb，gerrit服务启动失败，查看日志，报错信息如下：

gerrit的安装路径是/home/gerrit/gerrit_site,

查看gerrit_site的权限和属主，可能是之前的误操作，gerrit_site目录的属主不是gerrit：gerrit，而是777：gerrit。

执行命令：chown -R gerrit:gerrit gerrit_site

修改目录权限后，重启gerrit服务，正常运行。

over！
