Deploying NFS+RSYNC+SERSYNC+WEB01 Automation mounts with Ansible automation

1th ChapterThinking1.1How to use one clickAnsibleBuild1.1.1First Step goal

The first thing we want to make clear is that we need to implement a one-click Automation script that executes a script and then automates the installation of Nfs+rsync+sersync andthen lets web01 automatically mount the NFS shared directory.

1.1.2Second step relationship clear and sequential

Now that we have a goal, what we need to do is we need to understand the sequencing of automated installations.

1. since we need Ansible ansible

2. installed ansible Nfs share, and rsync backup. The peer

3. was installed Nfs and rsync Sersync

4. after we've installed it, the last thing we do is need WEB01 client mount

5. 1.3Ansible

Ansible is based on the Ssh-key. So we need ssh key login without password. But if you want a non-interactive key authentication login then we need to Sshpass and this package is ansible to provide (also can be directly yum installed), and if you want to install ansible So it is clear that Ansible is based on the Erel source, so the steps are as follows

1. Epel

2. Yum Ansible

3. Secret key authentication

4. Installing ansible

5. Modifying a configuration file

6. Determine if management is successful

7. 1.4Rsync

Rsync is a backup transfer, and his installation only needs to install rsync, create profiles, create password files, create users, modify permissions, start rsync

1.1.5Nfs

the need to be clear here is that NFS is based on Rpcbind , so we need to install the Rpcbind+nfs first , and then we need to clear the principle that NFS boot needs to find Rpcbind, to implement, so we need to start the Rpcbind first, at the start of NFS

1.1.6Sersync

to implement Sersync need to have this package, so we directly in the script RZ , but the system is not with the RZ command by default so we need to install Lrzsz first (I have my own RZ command for system optimization ). The configuration file is then modified to run in the background.

1.1.7web01

here web01 just as a client so we just hang on to him just fine and don't need anything else

2.4explanation

Here I am using install,sh to call ansible 's installation script, to install Ansible first , after installing and determining that there is no error, I call the execution of the index.yml . the Index.yml is the first copy of the Hosts file, then the installation call rsync installation script installation, after the call sersync installation script, install Sersync. After that, Yml lets ansible directly mount the directory that uses NFS to automatically share through web01 .
