[root@node1 src]# tar xf etcd-v3.2.9-linux-amd64.tar.gz cd etcd-v3.2.9-linux-amd64 cp etcd etcdctl /usr/local/bin/
然后开启etcd集群：
1、首先创建数据目录：mkdir /data/etcd -p
2、开启服务：
nohup etcd --name auto_scale --data-dir /data/etcd/ --listen-peer-urls http://192.168.44.134:2380,http://192.168.44.134:7001 --listen-client-urls http://192.168.44.134:2379,http://192.168.44.134:4001 --advertise-client-urls http://192.168.44.134:2379,http://192.168.44.134:4001 &
[root@node1 ~]# netstat -tunlp|grep etcd tcp 0 0 192.168.44.134:2379 0.0.0.0:* LISTEN 52094/etcd tcp 0 0 192.168.44.134:2380 0.0.0.0:* LISTEN 52094/etcd tcp 0 0 192.168.44.134:7001 0.0.0.0:* LISTEN 52094/etcd tcp 0 0 192.168.44.134:4001 0.0.0.0:* LISTEN 52094/etcd
1、创建一个key/value
[root@node1 ~]# curl -s http://192.168.44.134:2379/v2/keys/key1 -XPUT -d value="Hello world"
2、获取创建的key/value
[root@node1 ~]# curl -s http://192.168.44.134:2379/v2/keys/salt/haproxy/backend_www/www1
3、删除创建的key/value
[root@node1 ~]# curl -s http://192.168.44.134:2379/v2/keys/key1 -XDELETE
或者将上面的输出结果以json格式输出：
[root@node1 ~]# curl -s http://192.168.44.134:2379/v2/keys/salt/haproxy/backend_www/www1|python -m json.tool
{
"action": "get",
"node": {
"createdIndex": 9,
"key": "/salt/haproxy/backend_www/www1",
"modifiedIndex": 9,
"value": "192.168.44.134:8080"
}
}
将etcd配置在saltstack中，结合使用：
1、首先需要安装依赖包：
####config etcd my_etcd_config: etcd.host: 192.168.44.134 etcd.port: 4001 ext_pillar: - etcd: my_etcd_config root=/salt/haproxy
3、重启master
[root@node1 ~]# /etc/init.d/salt-master restart
结尾一直报错：
查找原因发现salt是python2.7安装的，而etcd是python2.6安装的，所以一直调用出错：
于是使用python2.7安装一遍etcd服务：
1、mv /usr/bin/python /usr/bin/python.bak 2、ln -s /usr/bin/python2.7 /usr/bin/python 3、修改/usr/bin/yum第一行为：#!/usr/bin/python2.6 4、wget https://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg --no-check-certificate 5、chmod +x setuptools-0.6c11-py2.7.egg 6、sh setuptools-0.6c11-py2.7.egg 7、wget https://pypi.python.org/packages/source/p/pip/pip-1.3.1.tar.gz --no-check-certificate 8、tar xf pip-1.3.1.tar.gz 9、cd pip-1.3.1 10、python setup.py install 11、/usr/bin/pip-2.7 install python-etcd
试着使用python2.7导入模块etcd，报错如下：
解决办法：
https://pypi.python.org/pypi/backports.ssl_match_hostname tar xf backports.ssl_match_hostname-3.5.0.1.tar.gz cd backports.ssl_match_hostname-3.5.0.1 python setup.py build python setup.py install
然后重启salt-master服务，查看设置的pillar：
[root@node1 ~]# curl -s http://192.168.44.134:2379/v2/keys/salt/haproxy/backend_www/www1 -XDELETE
{"action":"delete","node":{"key":"/salt/haproxy/backend_www/www1","modifiedIndex":12,"createdIndex":11},"prevNode":{"key":"/salt/haproxy/backend_www/www1","value":"192.168.44.134:8080","modifiedIndex":11,"createdIndex":11}}
[root@node1 ~]# salt ‘*‘ pillar.items
node2:
----------
backend_www:
----------
zabbix-agent:
----------
Zabbix_Server:
192.168.44.134
zabbix-agent-host:
----------
zabbix_host:
node2
现在通过添加etcd的key来增加haproxy后端的节点服务器：
curl -s http://192.168.44.134:2379/v2/keys/salt/haproxy/backend_www/www1 -XPUT -d value="192.168.44.134:8081"|python -m json.tool
2、查看pillar
[root@node1 ~]# salt ‘*‘ pillar.items
node1:
----------
backend_www:
----------
www1:
192.168.44.134:8081
3、修改haproxy配置文件：vim /srv/salt/prod/cluster/files/haproxy-outside.cfg
{% for www,www_ip in pillar.backend_www.iteritems() %}
server {{ www }} {{ www_ip }} check inter 1000
{% endfor %}
4、修改haproxy状态配置文件：vim /srv/salt/prod/cluster/haproxy-outside.sls
haproxy-service:
file.managed:
- name: /etc/haproxy/haproxy.cfg
- source: salt://cluster/files/haproxy-outside.cfg
- user: root
- group: root
- mode: 644
- template: jinja 新增一行，使用jinja模板，使用变量
测试并验证：
[root@node1 ~]# curl -s http://192.168.44.134:2379/v2/keys/salt/haproxy/backend_www/www2 -XPUT -d value="192.168.44.134:8080"|python -m json.tool
{
"action": "set",
"node": {
"createdIndex": 14,
"key": "/salt/haproxy/backend_www/www2",
"modifiedIndex": 14,
"value": "192.168.44.134:8080"
}
}
[root@node1 ~]# curl -s http://192.168.44.134:2379/v2/keys/salt/haproxy/backend_www/www3 -XPUT -d value="192.168.44.135:8080"|python -m json.tool
{
"action": "set",
"node": {
"createdIndex": 15,
"key": "/salt/haproxy/backend_www/www3",
"modifiedIndex": 15,
"value": "192.168.44.135:8080"
}
}
查看设置的pillar：
[root@node1 ~]# salt ‘*‘ pillar.items
node2:
----------
backend_www:
----------
www1:
192.168.44.134:8081
www2:
192.168.44.134:8080
www3:
192.168.44.135:8080
