安装nginx成功，并且查看nginx.conf也成功根据模板创建，但是start nginx service的任务失败，main.yml中的相关部分和输出日志如下：

另外，我想问下老师，ansible的执行日志去哪个路径查呢？

main.yml：

• name: start nginx service
  service: name=nginx state=started

log：
TASK [testbox : run the script] *******************************************************
changed: [test.example.com]

TASK [testbox : write the nginx config file] ******************************************
ok: [test.example.com]

TASK [testbox : ensure nginx is at the latest version] ********************************
ok: [test.example.com]

TASK [testbox : start nginx service] **************************************************
fatal: [test.example.com]: FAILED! => {“changed”: false, “msg”: “Unable to start service nginx: Job for nginx.service failed because the control process exited with error code. See “systemctl status nginx.service” and “journalctl -xe” for details.
”}
to retry, use: --limit @/home/deploy/test_playbooks/deploy.retry
