一、环境

1.实验主机信息

ansible管理机：
主机名：liang
IP：10.0.0.128
nginx(php)：
主机名：nginx
IP：10.0.0.131
IP：10.0.0.132
haproxy:
主机名：haproxy
IP：10.0.0.130
mysql(nginx):
主机名：mysql
IP：10.0.0.132

2.实验结构图

二、部署：

1.roles结构与配置

1.1编辑hosts清单

[root@liang ~]# cat /etc/ansible/hosts
# This is the default ansible 'hosts' file.
[haproxy]
10.0.0.130
[nginx]
10.0.0.131
10.0.0.132
[mysql]
10.0.0.132

1.2创建结构目录

[root@liang ~]# mkdir /roles/{nginx,haproxy,mysql}/tasks -p

1.3创建头文件

[root@liang ~]# cd /roles/
[root@liang roles]# cat site.yml
---
- name: install nginx

hosts: nginx
roles:
- nginx
- name: install mysql

hosts: mysql
roles:
- mysql
- name: install haproxy

hosts: haproxy
roles:
- haproxy

2.nginx+php角色编辑与配置

2.1创建目录与php文件

[root@liang roles]# mkfir nginx/templates/
[root@liang roles]# cat nginx/templates/index.html.j2

{{ ansible_default_ipv4.address }

2.2创建nginx角色入口文件

[root@liang roles]# cat nginx/tasks/main.yml 
---
- name: install nginx
yum: name=nginx state=present
- name: install php
yum: name=php state=present
- name: copy file
template: src=index.html.j2 dest=/usr/share/nginx/html/index.html
- name: start nginx
service: name=nginx state=started

3.mysql配置

3.1编辑mysql角色文件

[root@liang roles]# cat mysql/tasks/main.yml
---
- name: install mysql

yum: name={{item}} state=installed
with_items:
- mysql-server

- MySQL-python
- name: start mysql

service: name=mysqld state=started

4.haproxy配置

4.1创建目录与配置文件

[root@liang roles]# mkdir haproxy/templates
[root@liang roles]# cat haproxy/templates/haproxy.cfg.j2
global
log
127.0.0.1 local2
chroot
/var/lib/haproxy
pidfile
/var/run/haproxy.pid
maxconn
4000
user
haproxy
group
haproxy
daemon
stats socket /var/lib/haproxy/stats
defaults
mode
http
log
global
option
httplog
option
dontlognull
option http-server-close
option forwardfor
except 127.0.0.0/8
option

timeout queue
1m
timeout connect

timeout client

timeout http-keep-alive 10s
timeout check

maxconn
3000
frontend
main *:80
acl url_static
path_beg
-i /static /images /javascript /stylesheets
acl url_static
path_end
-i .jpg .gif .png .css .js
use_backend static
if url_static
default_backend
app
backend static
balance
roundrobin
server
static 127.0.0.1:8080 check
backend app
balance
roundrobin
{% for host in groups['nginx'] %}
server {{hostvars[host]['inventory_hostname']}} {{host}}:80}
{% endfor %}

4.2创建haproxy入口文件

[root@liang roles]# cat haproxy/tasks/main.yml
---
- name: install haproxy

yum: name=haproxy state=installed
- name: template file

template: src=haproxy.cfg.j2 dest=/etc/haproxy/haproxy.cfg owner=root group=root mode=644
- name: start haproxy

service: name=haproxy state=started enabled=yes

三、执行site.yml文件

[root@liang roles]# ansible-playbook site.yml
PLAY [install nginx] ***********************************************************************
TASK [Gathering Facts] *********************************************************************
ok: [10.0.0.132]
ok: [10.0.0.131]
TASK [nginx : install nginx] ***************************************************************
ok: [10.0.0.132]
ok: [10.0.0.131]
TASK [nginx : install php] *****************************************************************
ok: [10.0.0.132]
ok: [10.0.0.131]
TASK [nginx : copy file] *******************************************************************
ok: [10.0.0.132]
ok: [10.0.0.131]
TASK [nginx : start nginx] *****************************************************************
ok: [10.0.0.132]
ok: [10.0.0.131]
PLAY [install mysql] ***********************************************************************
TASK [Gathering Facts] *********************************************************************
ok: [10.0.0.132]
TASK [mysql : install mysql] ***************************************************************
ok: [10.0.0.132] => (item=[u'mysql-server', u'MySQL-python'])
TASK [mysql : start mysql] *****************************************************************
ok: [10.0.0.132]
PLAY [install haproxy] *********************************************************************
TASK [Gathering Facts] *********************************************************************
ok: [10.0.0.130]
TASK [haproxy : install haproxy] ***********************************************************
ok: [10.0.0.130]
TASK [haproxy : template file] *************************************************************
changed: [10.0.0.130]
TASK [haproxy : start haproxy] *************************************************************
changed: [10.0.0.130]
PLAY RECAP *********************************************************************************
10.0.0.130
: ok=4
changed=2
unreachable=0
failed=0
10.0.0.131
: ok=5
changed=0
unreachable=0
failed=0
10.0.0.132
: ok=8
changed=0
unreachable=0
failed=0

四、测试：

[root@liang ~]# curl 10.0.0.130
10.0.0.132
[root@liang ~]# curl 10.0.0.130
10.0.0.131
[root@liang ~]# curl 10.0.0.130
10.0.0.132
[root@liang ~]# curl 10.0.0.130
10.0.0.131
