CentOS7 部署ansible

ansible安装

---

 

1.yum安装：

[root@localhost  ~]# yum -y install epel-release
[root@localhost  ~]# yum -y install ansible

2.编辑/etc/ansible/hosts文件:

[root@localhost ~]# vim /etc/ansible/hosts
[websevers]

192.168.0.37
192.168.0.45
192.168.0.46
192.168.0.47
192.168.0.48
192.168.0.49

3.ssh认证：

[root@localhost  ~]# yum install -y sshpass 
[root@localhost  ~]# ssh-keygen -f /root/.ssh/id_rsa -P '' 
[root@localhost  ~]# export IP="192.168.1.61 192.168.1.62 192.168.1.63 192.168.1.64 192.168.1.65"           #如做host解析，直接使用hostname 
[root@localhost  ~]# export SSHPASS=123123 

[root@localhost  ~]# for HOST in $IP;do sshpass -e ssh-copy-id -o StrictHostKeyChecking=no $HOST ;done

或者生成ip文件推送密钥

[root@localhost  ~]# for i in {99..128};do echo 172.16.51.$i >> iplist.txt;done
[root@localhost  ~]# vim sshpush.sh
#!/usr/bin/bash
export SSHPASS="123456"
for i in `cat /root/iplist.txt`
do
sshpass -e ssh-copy-id -o StrictHostKeyChecking=no $i
done
[root@localhost ~]# sh sshpush.sh
