CentOS 7 x86_64 Minimal
配置网络：
vi /etc/sysconfig/network-scripts/ifcfg-eth0
NAME=eth0 TYPE=Ethernet ONBOOT=yes BOOTPROTO=static IPADDR=172.16.4.243 GATEWAY=172.16.4.254 NETMASK=255.255.255.0 DNS1=114.114.114.114
systemctl restart network
安装 ansible：
easy_install simplejson easy_install pip yum install gcc python-devel easy_install ansible pip list
自动把远程主机的公钥加入known_hosts：
vi /etc/ssh/ssh_config
StrictHostKeyChecking no
systemctl reload sshd
设置无密码ssh访问远程主机：
ssh-keygen -t rsa ssh-copy-id -i ~/.ssh/id_rsa.pub root@172.16.4.247
编辑远程主机列表：
主机列表可以是静态配置文件，也可以通过external inventory scripts动态获取，通过 -i 选项指定。
vi ~/hosts
# hosts [test] 172.16.4.247
测试远程主机的运行状态：
ansible all -i ~/hosts -m ping
YUM安装软件：
ansible all -i ~/hosts -m yum -a 'name=libselinux-python state=present'
复制文件到远程主机并执行：
ansible all -i ~/hosts -m copy -a 'src=test.sh dest=/root' ansible all -i ~/hosts -a 'bash test.sh'
ansible api example：
#!/usr/bin/python import ansible.runner import sys # construct the ansible runner and execute on all hosts results = ansible.runner.Runner( host_list='/root/hosts', pattern='*', forks=10, module_name='command', module_args='which systemctl', ).run() if results is None: print "No hosts found" sys.exit(1) print "\033[32mUP ***********\033[0m" for (hostname, result) in results['contacted'].items(): if not 'failed' in result: if len(result['stdout']): print "%s >>>stdout: %s" % (hostname, result['stdout']) if len(result['stderr']): print "%s >>>stderr: %s" % (hostname, result['stderr']) print "\033[31mFAILED *******\033[0m" for (hostname, result) in results['contacted'].items(): if 'failed' in result: print "%s >>> %s" % (hostname, result['msg']) print "\033[33mDOWN *********\033[0m" for (hostname, result) in results['dark'].items(): print "%s >>> %s" % (hostname, result)
