CENTOS7 Source Compilation Installation Ansible detailed deployment

First, the basic introduction
==========================================================================================
Ansible is a new automated operation tools, based on Python development, the collection of a number of operations tools (puppet, Cfengine, Chef, func, fabric) The advantages of the implementation of batch system configuration, batch program deployment, batch Run command and other functions.
Ansible is a module-based operation and does not have the capacity to deploy in bulk. The real batch deployment is the module that Ansible runs, and Ansible just provides a framework. Mainly include:
(1), connection plug-in connection plugins: responsible for and monitored by the end to achieve communication
(2), host Inventory: Specifies the operation of the hosts, is a configuration file inside the definition of monitoring host
(3), various modules core module, command module, custom module
(4), with the help of the plug-in to complete log mail and other functions;
(5), playbook: script when performing multiple tasks, it is not necessary to allow the node to run multiple tasks at once

1, ansible Basic installation
(1), python2.7 installation #目前还不支持3X的版本, you can also use

Https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tgztar xvzf PYTHON-2.7.8.TGZCD Python-2.7.8./configure-- Prefix=/usr/localmake && make Install

Copy the Python header file to a standard directory to avoid the need for header files when compiling ansible

Cd/usr/local/include/python2.7cp-a./*/usr/local/include/

Back up old versions of Python and sign links to new versions of Python

CD/USR/BINMV python python.oldln-s/usr/local/bin/python.

Modify the Yum script to point to the old version of Python and avoid it from running

Vim/usr/bin/yum modified to #!/usr/bin/python.old

2. Ansible Configuration
(1), SSH password-free key login settings
Implementation of SSH password-free authentication login on each machine separately

Vim/etc/ssh/sshd_config turn on rsaauthentication Yes # Enable RSA authentication Pubkeyauthentication Yes # Enable public key private key pairing authentication Mode Authorizedkeysfile. SS H/authorized_keys # Public key file path ssh-keygen-t RSA generate key File CD ~/.ssh/cat id_rsa.pub >> authorized_keyschmod Eys

All the machines ' keys are added to their authorized_keys.

To restart the SSH service:

/bin/systemctl Restart Sshd.service

(2), ansible configuration

Mkdir-p/etc/ansiblevim/etc/ansible/ansible.cfginventory      =/etc/ansible/hostsremote_port    = 22

Host group definition

vim/etc/ansible/hosts[web59]192.168.1.59

(3), simple test

Ansible all-m command-a ' uptime '              192.168.1.229 | SUCCESS | Rc=0 >> 13:00:08 up 5 days, 18:58,  2 users,  load average:0.01, 0.03, 0.00192.168.1.59 | SUCCESS | Rc=0 >> 13:03:29 up 5 days, 19:20,  5 users,  load average:0.00, 0.00, 0.00

3, the use of common modules
(1), Setup
To view some basic information about a remote host

Ansible web59-m Setup

(2), ping
Used to test the running state of a remote host

Ansible all-m Ping

(3), file
Setting the properties of a file

Force: There are two cases of forcing the creation of a soft link, one where the source file does not exist, but it will be established later, the other is the target soft link already exists, need to first cancel the previous soft chain, and then create a new soft chain, there are two options: yes|nogroup: Definition File/ Genus of Directories mode: Define permissions for files/directories owner: Define the File/directory's master path: Required option, define path to File/directory recurse: Recursive settings file properties, only valid for directory src: source file path linked, only for state= Link situation dest: The path that is linked to, applies only to State=link case state:directory: If the directory does not exist, create a directory file: Even if the file does not exist, will not be created link: Create a soft link hard: Create a rigid link touch: If the file does not exist, a new file is created, and if the file or directory already exists, update its last modified time absent: Deleting a directory, file, or unlinked file

Remote file Symbolic link creation

Ansible web59-m file-a "Src=/root/aa dest=/tmp/aa state=link"

Remote File Information view

Ansible web59-m command-a "Ls-al/tmp/aa"

Remote file Symbolic link deletion

Ansible web59-m file-a "Path=/tmp/aa state=absent"

(4), copy
Copying files to a remote host
The relevant options are as follows:

Backup: Before overwriting, the source file is backed up, and the backup file contains the time information. There are two options: yes|nocontent: Used instead of "src", you can directly set the value of the specified file dest: Required option. To copy the source file to the absolute path of the remote host, if the source file is a directory, the path must also be a directory Directory_mode: Recursively set the permissions of the directory, default to the system default permissions force: If the target host contains the file, but the content is different, if set to Yes, Then the overwrite is enforced, and if no, the file is copied only if the target location for the destination host does not exist. The default is yesothers: All the options in the file module can be used here src: a local file that is copied to the remote host, either an absolute path or a relative path. If the path is a directory, it will be replicated recursively. In this case, if the path ends with "/", only the contents of the directory are copied, and if "/" is not used to end, the entire content, including the directory, is copied, similar to rsync.

Copy Local single file "/ROOT/AA" to remote server

Ansible web59-m copy-a "Src=/root/aa dest=/tmp/aa owner=root group=root mode=0644"

Copy a local folder "/root/123" to a remote server

Ansible web59-m copy-a "src=/root/123 dest=/tmp/"

Remote File Information view

Ansible web59-m command-a "Ls-al/tmp/aa"

(5), command

The relevant options are as follows:

Creates: A filename, when the file exists, the command does not perform free_form: The Linux command to execute chdir: Before executing the instruction, switch to the directory removes: A file name, when the file does not exist, Then this option does not execute executable: Switch the shell to execute the instruction, the execution path must be an absolute path

Executing commands on a remote host

Ansible web59-m command-a "uptime"

(6), Shell
Switch to a shell to execute the specified instruction, with the same parameters as the command.
Unlike command, this module can support the command pipeline while another module also has this capability: raw

First create a shell script locally

Vim/tmp/test.sh#!/bin/bashdate +%f_%h:%m:%s

Distribute the created script file to the remote

Ansible web59-m copy-a "src=/tmp/test.sh dest=/tmp/test.sh owner=root group=root mode=0755"

Remote execution

Ansible web59-m shell-a "/tmp/test.sh"
