service centos

在上CentOS写了一个服务，使用命令systemctl start servicename 启动服务时，遇到如下错误：

Job for vktdemo.service failed because the control process exited with error code.
See "systemctl status vktdemo.service" and "journalctl -xe" for details.

使用命令查看日志如下：

[root@test system]# journalctl -xe

查询结果如下：

-- Automatic restarting of the unit vktdemo.service has been scheduled, as the result for
-- the configured Restart= setting for the unit.

这个错误引起的原因也是简单，就是我们上传的这个文件 /home/vktservice/demokt.demo.workerservice.dll 使用systemd 账号无执行权限。解决办法如下：

[root@vkt01 myadmin]# chmod -R 775 /home/vktservice/demo/

把执行权限下放到相关用户。现在再试一下是不是解决你的问题了？

庭院深深深几许？杨柳堆烟，帘幕无重数。
玉勒雕鞍游冶处，楼高不见章台路。
雨横风狂三月暮。门掩黄昏，无计留春住。
泪眼问花花不语，乱红飞过秋千去。
