apache，httpd 服务启动报错解决方法【linux 用日志排错方法

• 启动服务：systemctl start httpd， 成功

• 说明一下，我之前以为把配置文件改了重启就会报错，然而发现配置文件不是关键，而是 mod_wsgi 服务，我把 mon_wsgi 卸载以后重启就报错了，把 mon_wsgi 装上以后就重启正常了，这里这么做，只是 测试 如何看日志 以及 如果通过日志 处理报错问题。

• wsgi 正确路径建议指定如下图哦：

[](()etcd 启动报错【journalctl 定位】

=====================================================================================

• 报错内容如下：

[root@vms160 ~]# systemctl restart etcd

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

[root@vms160 ~]#

[](()解决步骤

[](()方式一【journalctl】

• 启动报错的时候下面会提醒你输入 systemctl status httpd.service 或journalctl -xe查看详细

[root@vms160 ~]# systemctl restart etcd

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

[root@vms160 ~]#

• 说明

• systemctl status httpd.service：既然服务起不来，那么看的这个状态肯定是 failed 的。

• journalctl -xe：这是直接查看日志，这里面可能会有关键字

这个呢，就注意看有没有：invalid value这个开头的关键字，如果有的话，一般后面就是报错内容了

可以这样：journalctl -xe | grep "invalid value"过滤哦。

这种更实用于你知道这个配置文件，且知道这行内容是啥的情况。

如下：

[root@vms160 ~]# journalctl -xe | grep "invalid value"
