直接看异常吧：
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

这种问题单看日志是没什么东西的，实际都是 phantomjs 没有正常启动导致的，处理方式可以直接从项目里找到代理命令后执行：
./phantomjs --webdriver=58001 --webdriver-logfile=/data/logs/phantomjs.log
输出可能是这样的：
Unable to open file '/data/logs/phantomjs.log'
phantomjs://platform/fs.js:79 in open
phantomjs://platform/logger.js:95 in addLogFile
phantomjs://platform/config.js:76 in apply
phantomjs://platform/config.js:98 in init
很明显是文件权限不足了，通过 chmod 命令修改即可。
还一个可能是启动正常、日志正常，但是 java 进程仍然报异常，这个可能是网络导致的，java 进程启动 phantomjs 进程后会请求 http://localhost:port/status 地址进行状态监测，如果没有监测到也会认为启动失败，例如：
[~]# curl http://localhost:58001
curl: (6) Couldn't resolve host 'localhost'
这种情况修改 /etc/hosts 添加 127.0.0.1 localhost 的映射就可以了。
