自动化运维工具ANSIBLE(六)

配置基于key的免密登陆远程主机

[ansible]# mkdir -pv /project/scripts/
[ansible]# vim /project/scripts/key.sh
#!/bin/bash
#
 ssh-keygen -P "" -t rsa -f /root/.ssh/id_rsa &> /dev/null
rpm -q expect &> /dev/null || yum install expect -y &> /dev/null
cat <<-EOF > host.pw
192.168.209.9 node1
192.168.209.49 node2
192.168.209.29 node3
192.168.209.39 node4
192.168.209.59 node5
EOF
while read IP PW;do
expect <<EOF
set timeout 20
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub root@$IP
expect {
"yes/no" { send "yes\n";exp_continue }
"password" { send "$PW\n" }
}
expect eof
EOF
done < host.pw

安装ansible，配置主机清单

[root@ansible ~]# yum-config-manager --enable sohu
[root@ansible ~]# yum-config-manager --enable epel
[root@ansible ~]# yum install ansible -y
[root@ansible ~]# ansible --version
[root@ansible ~]# vim /etc/ansible/hosts
[allnode]
192.168.209.9
192.168.209.29
192.168.209.39
192.168.209.49
192.168.209.59

[httpdsrvs]
192.168.209.9

ansible批量安装 mariadb-server(二进制)并启动

[root@ansible ~]# mkdir -pv /project/playbook/roles/mariadb/{vars,files,templates,handlers,tasks}
[root@ansible ~]
