吐槽: 好久沒寫博文了，這次是忍不住了。。yum裝個glusterfs，測個東西。
但是啓動一直報錯，搜了下網上的方法，一股腦全是更換文件目錄的。懶得吐槽了
背景描述:
- 系統 centos7.2
- glusterfs: yum
問題描述
簡單來說，報錯就是systemctl的報錯，然後在systemd上配置DEBUG是不出現內容的，也嘗試進行各個目錄權限的修改等等，都無效。
報錯:

* 首先從/usr/lib/systemd/system/glusterd.service中獲取啓動的命令: /usr/sbin/glusterd -p /var/run/glusterd.pid --log-level ......
* 手動執行上述命令，發現無返回，echo $?爲1，異常退出；
* 然後 /usr/sbin/glusterd --help獲取添加日誌路徑；
* 得出命令: /usr/sbin/glusterd -f /etc/glusterfs/glusterd.vol -p /var/run/glusterd.pid --log-level DEBUG --log-file /var/log/gluster.log
* 執行後發現DEBUG信息DEBUG信息

猜了下可能和ssl有關，爲了圖省事，直接yum -y install openssl-devel
啓動成功
