我是 ansible 新手。现在我尝试重新启动我的 Tomcat 服务。看起来 ansible 无法检测服务状态（已启动/已停止）并且无法（重新）启动它。请告诉我如何进行诊断？
参见此处（rotor-app-01.dev是 Tomcat 主机。brutus-HP-ENVY-17是我的本地主机）：
[email protected]:~
$ sudo service tomcat stop
Using CATALINA_BASE: /opt/vendor/tomcat
Using CATALINA_HOME: /opt/vendor/tomcat
Using CATALINA_TMPDIR: /opt/vendor/tomcat/temp
Using JRE_HOME: /home/vendor/jdk1.6.0_45
Using CLASSPATH: /home/vendor/jdk1.6.0_45/lib/tools.jar:/opt/vendor/tomcat/bin/bootstrap.jar:/opt/vendor/webapps/app/config
Using CATALINA_PID: /var/run/vendor/tomcat.pid
Tomcat is stopped [ OK ]
[email protected]:~
$ sudo service tomcat status
Tomcat is stopped [ OK ]
现在 Tomcat 已停止。让我们启动它！

剧本已播放。让我们检查一下 Tomcat 状态：
[email protected]:~
$ sudo service tomcat status
Tomcat is stopped [ OK ]
[email protected]:~
$ ps -ef | grep java
user 58396 56290 0 16:52 pts/1 00:00:00 grep java
Tomcat 是向下！但在 ansible 状态中，该服务被标记为已更改. 检查服务脚本（可以启动Tomcat吗？）
[email protected]:~
$ sudo service tomcat start
find: `/opt/vendor/tomcat/webapps/*': No such file or directory
find: `/opt/vendor/tomcat/temp/*': No such file or directory
Using CATALINA_BASE: /opt/vendor/tomcat
Using CATALINA_HOME: /opt/vendor/tomcat
Using CATALINA_TMPDIR: /opt/vendor/tomcat/temp
Using JRE_HOME: /home/vendor/jdk1.6.0_45
Using CLASSPATH: /home/vendor/jdk1.6.0_45/lib/tools.jar:/opt/vendor/tomcat/bin/bootstrap.jar:/opt/vendor/webapps/app/config
Using CATALINA_PID: /var/run/vendor/tomcat.pid
Tomcat is started [ OK ]

$ sudo service tomcat status
Tomcat is running [ OK ]
服务单正确！以下是一些信息：

答案1
解决了：
CentOS 上的默认行为sudo是问题的根源。该sudo命令需要 TTY。我已Defaults requiretty在文件中禁用该选项/etc/sudoers并解决了此问题。
答案2
以下是我停止和重新启动服务的操作（以 postfix 为例）。
任务文件.yml：
- service: name=postfix state=restarted
剧本.yml：
- name: My Playbook
hosts: my_hostgroup
tasks:
- include ./taskfile.yml
become: yes
become_method: sudo
become_user: root
对我来说效果很好
