二、安装

1、rpm安装

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm -y
yum install ansible

 

三、配置

1、默认配置优化

vim /etc/ansible/ansible.cfg
forks          = 50   #更改默认工作进程为50，默认为5
log_path = /var/log/ansible.log    #开启日志记录

 

 2、配置资源清单

vim /etc/ansible/hosts 
[tomcat]
192.168.1.190
192.168.1.170
192.168.1.210
192.168.1.211
192.168.1.212
192.168.1.213
192.168.1.214
192.168.1.216
192.168.1.219
192.168.1.220
192.168.1.221
192.168.1.222
192.168.1.223

 

3、配置SSH无秘钥链接

ssh-keygen    #本地生成公钥和私钥
ssh-copy-id root@192.168.1.220    #拷贝公钥到业务主机

 

 4、测试链接性

ansible tomcat -m ping -o
