一、安装1、yum安装
1.1、安装epel源
yum -y install python-jinja2 PyYAML python-paramiko python-babel python-crypto
1.2、安装ansible
yum install ansible
2、编译安装
2.1、安装依赖
yum -y install python-jinja2 PyYAML python-paramiko python-babel python-crypto
2.2、下载
wget https://codeload.github.com/ansible/ansible/zip/stable-2.5
2.3、安装
python setup.py build && python setup.py install mkdir /etc/ansible && cp -r examples/* /etc/ansible
二、配置ansible的可管理主机
1、配置ansible的hosts文件，添加主机组
echo -e "[webserver]\n192.168.12.157\n192.168.12.158" >>/etc/ansible/hosts
2、配置免秘钥登录
ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.12.157 ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.12.158
三、测试执行命令
[root@linux-test-node1 ~]# ansible webserver -m command -a who 192.168.12.157 | SUCCESS | rc=0 >> root tty1 2018-06-06 09:33 root pts/0 2018-06-06 09:34 (192.168.12.136) root pts/1 2018-06-06 10:19 (192.168.12.156) 192.168.12.158 | SUCCESS | rc=0 >> root tty1 2018-02-27 01:14 root pts/0 2018-02-27 01:15 (192.168.12.136) root pts/1 2018-02-27 01:59 (192.168.12.156)
四、ansible的常用模块
4.1、command模块
[root@linux-test-node1 ~]# ansible webserver -a "echo john@2018 |passwd root" 192.168.12.157 | SUCCESS | rc=0 >> john@2018 |passwd root 192.168.12.158 | SUCCESS | rc=0 >> john@2018 |passwd root
注：-m command可以省略，command模块不支持命令管道，需要使用shell模块，上面的命令并没有更改密码
4.2、shell模块
[root@linux-test-node1 ~]# ansible webserver -m shell -a "echo john@2018 |passwd --stdin root" 192.168.12.157 | SUCCESS | rc=0 >> Changing password for user root. passwd: all authentication tokens updated successfully. 192.168.12.158 | SUCCESS | rc=0 >> 更改用户 root 的密码 。 passwd： 所有的身份验证令牌已经成功更新。
4.3、copy模块，将本地的文件拷贝到目标服务器，grou、owner、mode根据需要加
[root@linux-test-node1 ~]# ansible webserver -m copy -a "src=~/ansible_test.file dest=/root/ mode=644 owner=root group=root"
192.168.12.158 | SUCCESS => {
"changed": true,
"checksum": "172c1d29d7392d0959d56c947052f4fe19095f1a",
"dest": "/root/ansible_test.file",
"gid": 0,
"group": "root",
"md5sum": "24786862312ecb05a2d09613dff5f1e0",
"mode": "0644",
"owner": "root",
"secontext": "system_u:object_r:admin_home_t:s0",
"size": 23,
"src": "/root/.ansible/tmp/ansible-tmp-1510458019.96-84135187555991/source",
"state": "file",
"uid": 0
}
192.168.12.157 | SUCCESS => {
"changed": true,
"checksum": "172c1d29d7392d0959d56c947052f4fe19095f1a",
"dest": "/root/ansible_test.file",
"gid": 0,
"group": "root",
"md5sum": "24786862312ecb05a2d09613dff5f1e0",
"mode": "0644",
"owner": "root",
"secontext": "system_u:object_r:admin_home_t:s0",
"size": 23,
"src": "/root/.ansible/tmp/ansible-tmp-1510458019.95-16654666556198/source",
"state": "file",
"uid": 0
}4.4、fetch模块，从远程主机拷贝文件到本地
[root@linux-test-node1 ~]# ansible webserver -m fetch -a "src=/root/remote_test.file dest=/root/ flat=yes"
192.168.12.158 | FAILED! => {
"changed": false,
"msg": "file not found: /root/remote_test.file"
}
192.168.12.157 | SUCCESS => {
"changed": true,
"checksum": "76d7d1e26b7507b6aa5f7add865b7585e6a4435c",
"dest": "/root/remote_test.file",
"md5sum": "27c3eb98c1f99ff12a1184af1113481d",
"remote_checksum": "76d7d1e26b7507b6aa5f7add865b7585e6a4435c",
"remote_md5sum": null
}
flat=yes作用：
当dest=/root/，abc.txt会保存在/root/目录下
当dest=/root/file，会拷贝abc.txt文件，并命名为file4.5、cron模块
1、新建任务
[root@linux-test-node1 ~]# ansible webserver -m cron -a "minute=*/10 job='/sbin/ntpdate 10.10.10.10 &> /dev/null' name=Synctime"
192.168.12.158 | SUCCESS => {
"changed": true,
"envs": [],
"jobs": [
"Synctime"
]
}
192.168.12.157 | SUCCESS => {
"changed": true,
"envs": [],
"jobs": [
"Synctime"
]
}注：name是计划任务的注释，minute是执行时间，job是完整的任务
2、删除任务
[root@linux-test-node1 ~]# ansible webserver -m cron -a "state=absent name=Synctime"
192.168.12.158 | SUCCESS => {
"changed": true,
"envs": [],
"jobs": []
}
192.168.12.157 | SUCCESS => {
"changed": true,
"envs": [],
"jobs": []
}4.6、file模块，对文件、文件夹进行删除、创建、移动拷贝和创建链接的操作
创建文件 [root@linux-test-node1 ~]# ansible webserver -m file -a "path=/root/test_touch_file state=touch owner=root group=root mode=644" 删除文件 [root@linux-test-node1 ~]# ansible webserver -m file -a "path=/root/test_touch_file state=absent" 创建链接 [root@linux-test-node1 ~]# ansible webserver -m file -a "src=/root/ansible_test.file dest=/home/ansible_test.file state=link"
4.7、yum模块
安装 [root@linux-test-node1 ~]# ansible webserver -m yum -a "name=httpd" 卸载 [root@linux-test-node1 ~]# ansible webserver -m yum -a "name=httpd state=absent"
4.8、service模块
启动httpd服务 [root@linux-test-node1 ~]# ansible webserver -m service -a "name=httpd state=started" 停止服务 [root@linux-test-node1 ~]# ansible webserver -m yum -a "name=httpd state=stopped" 重启服务 [root@linux-test-node1 ~]# ansible webserver -m yum -a "name=httpd state=restarted"
4.9、user\group模块，用来管理用户和组
新建用户 [root@linux-test-node1 ~]# ansible webserver -m user -a "name=john group=root" 删除用户 [root@linux-test-node1 ~]# ansible webserver -m user -a "name=john state=absent remove=yes" 新建组 [root@linux-test-node1 ~]# ansible webserver -m group -a "name=johngrp" 删除组 [root@linux-test-node1 ~]# ansible webserver -m group -a "name=johngrp state=absent
