roles(角色）

本文主要是介绍roles(角色），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

创建目录，编写剧本下载nginx:

  184  mkdir /etc/ansible/playbook

  185  vim /etc/ansible/playbook/nginx.yml

---
-       hosts:  groupremote_user:    roottasks:-       name:   卸载httpdyum:    name=httpd      state=absent-       name:   安装nginxyum:    name=nginx      state=present-       name:   修改配置文件shell:  echo 'i am nginx,port is 80' > /usr/share/nginx/html/index.html-       name:   修改端口command:        sed -i '/listen/s/80/8080/g' /etc/nginx/nginx.confnotify:-       restart nginx-       name:   启动服务service:        name=nginx   state=started  enabled=yeshandlers:-       name:   restart nginxservice:        name=nginx      state=restarted

  186  ansible-playbook /etc/ansible/playbook/nginx.yml 
 

roles

用roles（角色）来下载nginx

创建roles的目录结构：

[root@nat ~]# cd /etc/ansible/roles
[root@nat roles]# ls
[root@nat roles]# mkdir nginx
[root@nat roles]# ls
nginx
[root@nat roles]# cd nginx/
[root@nat nginx]# mkdir files
[root@nat nginx]# mkdir tasks
[root@nat nginx]# mkdir handlers
[root@nat nginx]# mkdir templates
[root@nat nginx]# mkdir vars
[root@nat nginx]# mkdir meta

创建文件：

[root@nat nginx]# touch handlers/main.yml
[root@nat nginx]# touch tasks/main.yml
[root@nat nginx]# touch vars/main.yml
[root@nat nginx]# touch meta/main.yml

[root@nat nginx]# tree
.
├── files
├── handlers
│   └── main.yml
├── meta
│   └── main.yml
├── tasks
│   └── main.yml
├── templates
└── vars
    └── main.yml

6 directories, 4 files
 

编辑文件：

[root@nat ~]# vim /etc/ansible/playbook/test002.yml

---
-       hosts:  groupremote_user:    rootroles:-       nginx
...

[root@nat ~]# ansible-playbook /etc/ansible/playbook/test002.yml

[root@nat ~]# tree /etc/ansible/roles
/etc/ansible/roles
└── nginx
    ├── files
    ├── handlers
    │   └── main.yml
    ├── meta
    │   └── main.yml
    ├── tasks
    │   └── main.yml
    ├── templates
    └── vars
        └── main.yml

[root@nat ~]# vim /etc/ansible/roles/nginx/tasks/main.yml 

---
-       name:   卸载httpdyum:    name=httpd      state=absent
-       name:   卸载nginxyum:    name=nginx      state=absent
-       name:   安装nginxyum:    name=nginx      state=present
-       name:   启动服务service:    name=nginx      state=started   enabled=yes
...

[root@nat ~]# ansible-playbook /etc/ansible/playbook/test002.yml

使用roles实现lnmp

nginx改配置8080

mariadb中创建eleme数据库，创建表user

[root@nat ~]# cd /etc/ansible/
[root@nat ansible]# mkdir script
[root@nat ansible]# cd script/
[root@nat script]# vim dbtable.sh

[root@nat script]# vim /etc/ansible/playbook/test003.yml

[root@nat script]# cd /etc/ansible/roles
[root@nat roles]# ls
nginx
[root@nat roles]# cp -r nginx mariadb
[root@nat roles]# ls
mariadb  nginx
[root@nat roles]# cd mariadb
[root@nat mariadb]# ls
files  handlers  meta  tasks  templates  vars
[root@nat mariadb]#  vim /etc/ansible/roles/mariadb/tasks/main.yml 

[root@nat]# ansible-playbook /etc/ansible/playbook/test003.yml
