Automated operations Tools: ansible Application scenario for multi-process call Ansible API: Application System Check An application system may have a cluster of 20-50 servers, and a preliminary system-level check can be checked with a unified playbook, such as (Df-h command). But deep into the application layer, there are some personalized applications, such as 2 HTTP servers, 20 middleware

The CMDB crawls service information in many ways, using automated tools Saltstack, Ansible, puppet, or using other modules to directly SSH remote connections to fetch server information. Here is a record of using the Ansible API interface to invoke the Setup module fetch.Experiment using two machines Ip System Software 192.168.93.137 Centos6.5_x64

The use of Ansible also has a long time, the previous machine is a good template, configuration of SSH without password landing, push up generally very convenient. Today, there is nothing to do, just have a thing to do, the plaintext password push sample paste out to share.Straight into the topic,Requirements: Modify the Hosts file of a batch of machines, require sudo permission, and sudo account (I am here is CentOS account,) No SSH password login is

After we've installed the ansible,Password-free login is configured.Now we can check the connectivity of management hosts and managed hostsAnsible all-m PingIn our actual production we tend to use sudo to perform root permissions for ordinary users.Ansible all-m ping-u Ansible-sudoWe can find a directory to create a host list file inventory.cfgIf we create it in the home directory,Cat/home/inventory.cfg[Web

the service, only need to adjust the upload package script sequence, first upload the installation package, the subsequent operation is performed normally. 2) Iteration Update, the function is slightly modified, the original configuration item does not need to modify, also simply adjusts the upload installs the package script sequence, obtains the original configuration first, then uploads the update installs the package, the subsequent operation normal execution. 3.3 Comparison of advantages a

Frontier: ansible are all good, so let's talk about lookup plugins this plugin. Lookup_plugins is mainly used to implement extensions of various strings and variables within the extended playbook. For me personally, the use is not too big, but looked at the official Lookup_plugins extension list, there are some ideas. When you first use lookup, you encounter a problem where the data in {lookup}} is not processed and no solution is found, and t

Using the shell module, the remote command is executed through/bin/sh, so we can use the various command methods in the terminal input;But we define our own environment variables in. Bashrc/.bash_profile The shell module is not recognized because it is not loaded, and if you need to use a custom environment variable, you need to execute the statement that loads the custom script at the very beginning;The use of shell modules can be divided into two blocks:shell module uses the same as the comman
