Automating operations-simple implementation with shell scripts

Review:

1 Installing ETCD

[[Email protected] ~]# pip install PYTHON-ETCD install ETCD software

2 Modify Salt-master configuration file, add configuration, and restart Salt-master

[Email protected] ~]# Vim/etc/salt/master

Etcd_pillar_config:

etcd.host:10.0.0.7

etcd.port:4001

Ext_pillar:

-Etcd:etcd_pillar_config root=/salt/haproxy/

3 Adding nodes

[Email protected] ~]# curl-s http://10.0.0.7:2379/v2/keys/salt/haproxy/backend_www_oldboyedu_com/web-node4-XPUT-d Value= "10.0.0.7:8080" | Python-m Json.tool

4 Change Haproxy-outside.sls file add Jinja template flag

[Email protected] ~]# Vim/srv/salt/prod/cluster/haproxy-outside.sls

-Template:jinja

5 Modifying a configuration file

[Email protected] ~]# vim/srv/salt/prod/cluster/files/haproxy-outside.cfg

{% for web,web_ip in Pillar.backend_www_oldboyedu_com.iteritems ()-%}

server {{web}} {{web_ip}} Check inter 15 rise fall

{% ENDFOR%}

The script implementation automatically adds the machine:

[email protected] ~]# cat auto.sh

#!/bin/bash

Main_add_host=$1

Create_host () {

echo "Create host OK"

}

Deploy_service () {

#salt ' linux-node2.example.com ' State.sls nginx.install env=prod

add_host_port= "8080"

}

Deploy_code () {

echo "Deploy code OK"

}

Service_check () {

status=$ (curl-s--head/http "$ADD _host": "$ADD _host_port"/| grep ' OK ')

If [-N "$STATUS"];then

echo "OK"

Else

echo "Not OK"

Exit

Fi

}

Etcd_key () {

Add_host=$1

Curl http://10.0.0.7:2379/v2/keys/salt/haproxy/backend_www_oldboyedu_com/$ADD _host-xput-d value= "10.0.0.8:${add_ Host_port} "

}

Sync_state () {

Salt ' linux-node1.example.com ' State.sls cluster.haproxy-outside env=prod

}

Main () {

Create_host;

Deploy_service;

Deploy_code;

Etcd_key $MAIN _add_host;

Sync_state;

}
