代码如下:
$ fleetctl start db.1.service
$ fleetctl list-units
UNIT LOAD ACTIVE SUB DESC MACHINE
db.1.service loaded active running Run db_1 9c008961.../10.0.2.15
$ fleetctl start web.1.service
$ fleetctl list-units
UNIT LOAD ACTIVE SUB DESC MACHINE
db.1.service loaded active running Run db_1 9c008961.../10.0.2.15
web.1.service loaded active running Run web_1 9c008961.../10.0.2.15
$ fleetctl list-units
UNIT LOAD ACTIVE SUB DESC MACHINE
db.1.service loaded active running Run db_1 9c008961.../10.0.2.15
$ fleetctl start web.1.service
$ fleetctl list-units
UNIT LOAD ACTIVE SUB DESC MACHINE
db.1.service loaded active running Run db_1 9c008961.../10.0.2.15
web.1.service loaded active running Run web_1 9c008961.../10.0.2.15
现在你的程序运行起来了,但是服务还没有注册到etcd。幸运的是,fig2coreos已经为我们自动生成服务文件。
代码如下:
$ fleetctl start db-discovery.1.service
$ fleetctl start web-discovery.1.service
$ fleetctl list-units
UNIT LOAD ACTIVE SUB DESC MACHINE
db-discovery.1.service loaded active running Announce db_1 9c008961.../10.0.2.15
db.1.service loaded active running Run db_1 9c008961.../10.0.2.15
web-discovery.1.service loaded active running Announce web_1 9c008961.../10.0.2.15
web.1.service loaded active running Run web_1 9c008961.../10.0.2.15
$ etcdctl ls --recursive
/services
/services/web
/services/web/web_1
/services/db
/services/db/db_1
$ etcdctl get /services/web/web_1
{ "host": "core-03", "port": 80, "version": "52c7248a14" }
$ etcdctl get /services/db/db_1
{ "host": "core-03", "port": 3306, "version": "52c7248a14" }
$ fleetctl start web-discovery.1.service
$ fleetctl list-units
UNIT LOAD ACTIVE SUB DESC MACHINE
db-discovery.1.service loaded active running Announce db_1 9c008961.../10.0.2.15

web-discovery.1.service loaded active running Announce web_1 9c008961.../10.0.2.15

$ etcdctl ls --recursive

/services/db/db_1
$ etcdctl get /services/web/web_1
{ "host": "core-03", "port": 80, "version": "52c7248a14" }
$ etcdctl get /services/db/db_1
{ "host": "core-03", "port": 3306, "version": "52c7248a14" }
部署完成
就这样,搞定了。在Vagrant 1.5使用Vagrant Cloud账号,你可以访问你的WordPress应用。如下图:
代码如下:
$ cd ~/coreos-vagrant/cluster/
找出哪个机器监听着你的80端口:
代码如下:
$ etcdctl get /services/web/web_1
{ "host": "core-03", "port": 80, "version": "52c7248a14" }</p> <p>$ vagrant share core-03 --http 80
