ansible安装应用软件
1.创建相应的目录:
mkdir -p /ansible/roles/{nginx,mysql,tomcat,db,zabbix}/{defaults,files,handlers,meta,tasks,templates,vars}
2 文件结构
[root@MSJTVL-MJSP-A35 etc]# tree ansible/

各目录功能说明
3.解决“Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!”问题:
更新python库:
yum -y install libselinux-python

6、常见错误
7.补充
1.使用ssh-copy-id命令来复制Ansible公钥到节点中。
ssh-copy-id -i sm01@10.0.110.47
