rpm安装
下载epl源 ： Download the latest epel-release rpm from:http://dl.fedoraproject.org/pub/epel/6/x86_64
执行 wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
安装epel-release ：
# rpm -Uvh epel-release*rpm
安装ansible1.9
# yum install ansible1.9
ansible管理服务器（安装ansible的服务器）必须配置免密码登录其他需要管理的主机
各主机执行ssh-keygen生成私钥和公钥，并把所有主机的公钥追加到authorized_keys中，然后分发到ansible管理服务器
修改个主机的主机名，编辑/etc/hosts文件，把所有主机的ip和主机名写进去
[root@node01 .ssh]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.16.145.111 node01 172.16.145.112 node02 172.16.145.113 node03 172.16.145.114 node04 172.16.145.115 node05
接下来就可以配置 hosts文件了，
[root@node01 .ssh]# cat /etc/ansible/hosts [hadoop-all] node[01:05] [hadoop-master] node[04:05] [hadoop-slave] node[01:03] [zookeeper-all] node[01:03] [hdfs-nn] node[04:05] [hdfs-dn] node[01:03] [hdfs-jn] node[01:02] [yarn-rm] node[04:05] [yarn-nm] node[01:03] [hive-all] node[01:05] [hive-cli] node[01:05] [hive-meta] node[04:05] [hive-hs2] node[04:05] [impala-all] node[01:05] [impala-llama] node[04:05] [impala-catalog] node04 [impala-state] node04 [impala-impalad] node[01:03]
执行命令测试ansible能否ping通
[root@node01 .ssh]# ansible all -m ping
node03 | success >> {
"changed": false,
"ping": "pong"
}
node02 | success >> {
"changed": false,
"ping": "pong"
}
node01 | success >> {
"changed": false,
"ping": "pong"
}
node05 | success >> {
"changed": false,
"ping": "pong"
}
node04 | success >> {
"changed": false,
"ping": "pong"
}
执行服务停止重启命令
[root@node01 .ssh]# ansible impala-impalad -m service -a "name=impala-server state=restarted"
node01 | success >> {
"changed": true,
"name": "impala-server",
"state": "started"
}
node03 | success >> {
"changed": true,
"name": "impala-server",
"state": "started"
}
node02 | success >> {
"changed": true,
"name": "impala-server",
"state": "started"
}
ok,大功告成！
