Several basic statements of ansible

As the signing of the new club, the environment is very good, colleagues are very easy-going, the leadership is also very good to talk, overtime benefits are great, all in all, good work, a lot of money.

Batch processing tool My earliest contact is pssh, because it is very simple and rough, but it is too simple and rough, to cope with 10 sets of 20 machines is OK, to cope with 50 100 servers on the heart of the lack of power, and I do not like puppet, always feel that the thing with my eight, so, In the new boss's recommendation, I put my eyes on the ansible.

Ansible installation is very simple, in the Redhat environment directly #yum install ANSIBLE-Y on the line. Redhat has already acquired the Ansible company, so it offers no small convenience in installation.

Ansible after installation, will be in the/etc/ansible/directory to see a file called hosts, here is all the servers you want to control the IP, you can arrange to write, such as:

192.168.1.122

192.168.1.133

192.168.1.144

You can also write in groups, for example:

[Aliyun]

10.22.33.44

10.22.33.45

[Jinshanyun]

121.23.45.66

121.23.45.67

By default, Ansible will use the command for this hosts file, such as

#ansible all-m Ping 192.168.1.134-u Ashin

This means that the entire hosts in the machine to Ashin account start, and all to ping 192.168.1.134.

How to connect the host with the remote machine to be controlled after that, here are a few command statements:

1) #ansible all-m shell-a "/bin/echo Hello"

2) #ansible all-m copy-a "src=~/projects/tests/t.py dest=~"

3) #ansible all-m file-a "Dest=~/tests state=absent"

4) #ansible webservers-m copy-a ' dest=/root/src=/root/xl2pdf '

5) #ansible v1-m service-a "Name=mysql state=started"--sudo-k

6) #ansible all-m user-a "Name=foo password=foo"--sudo-k

7) #ansible v1-m apt-a "Name=git state=latest"
