\u2022<\/span> <\/span>This role will configure redhat 7 and up interfaces for virtual and physical.<\/strong>
\n(bonded <\/span>nics<\/span>, gateways, routes, interface names)<\/span><\/strong><\/div>\n<\/div>\n<\/div>\n

How to use this role:<\/span><\/p>\n

\n
\n
1.<\/span>You must first download the git repository into your <\/span>roles<\/span> directory usually ansible\/role\/<\/span><\/div>\n
\n
\n
a.<\/span>git clon<\/span>e <\/span>https:\/\/github.com\/Perfect10NickTailor\/setup-redhat-interfaces.git<\/a><\/div>\n<\/div>\n
\n
b.<\/span>https:\/\/github.com\/Perfect10NickTailor\/setup-redhat-interfaces<\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n
\n
2.<\/span>Now you want edit the <\/span>hosts.client<\/span> file <\/span>name file or create it if it doesn\u2019t exist<\/span> under your \u201c<\/span>ansible\/inventory\/<\/span>dev:staging:prod<\/span>\u201d directory. This is a good way to separate environments with ansible, inside each environment you should have a <\/span>hosts.file<\/span> like indicated below.<\/span><\/div>\n

Example file<\/span>: <\/span>hosts.<\/span>dev<\/span>, <\/span>hosts.staging<\/span>, <\/span>hosts.prod<\/span><\/p>\n

\n
\n
c.<\/span>Put your server under the appropriate group inside the file and save<\/span><\/div>\n<\/div>\n
\n
d.<\/span>testmachine1 <\/span>ansible_host<\/span>=192.168.1.101 <\/span><\/div>\n<\/div>\n<\/div>\n

.<\/span><\/span><\/p>\n

Cool Stuff<\/span>: <\/span>If you deployed a virtual-machine using the <\/span>ansible-<\/span>vmware<\/span> modules <\/span>it will set the hostname of the host using the same <\/span>shortname<\/span> of the <\/span>vm<\/span>. If you require the <\/span>fqdn<\/span> vs the <\/span>shortname<\/span> on the host. To solve this I added some code to set the<\/span> fdqn<\/span> as <\/span>the <\/span> new<\/span>_hostname<\/span> if you define it under you <\/span>hosts.file<\/span> as shown below.<\/span><\/strong><\/p>\n

\n

\n
\n
e.<\/span>testmachine1 <\/span>ansible_host<\/span>=192.168.1.101 new_hostname=testmachine1.nicktailor.com<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

.<\/span><\/span><\/p>\n

Now inside this directory you should see <\/span>hosts<\/span><\/strong> & <\/span>host_vars<\/span>, <\/span>group_vars<\/span><\/strong><\/p>\n

Descriptions:<\/span><\/strong><\/p>\n

\n
\n
f.<\/span>Hosts. <\/span><\/strong>\u2013 is where you will list your servers under specific groups which tell the playbook (what the server is, if it the server should have a specific task run on it, and how to find it)<\/span><\/div>\n<\/div>\n
\n
g.<\/span>Host_vars<\/span> <\/strong>\u2013 Inside this directory is where you list the server by name which is you will list under hosts. Inside these files you pass variable parameters to the specific roles when running your playbook. Without these the playbook <\/span>cant<\/span> do the tasks you want it to.<\/span><\/div>\n<\/div>\n
\n
h.<\/span>Group_vars<\/span> \u2013 <\/span><\/strong>Are how a way to group variables for sets of servers and this keeps code cleaners and easier to manage<\/span>.<\/span><\/strong><\/div>\n<\/div>\n<\/div>\n
