写一段ansible，用来安装mysql主从

服务器。

好的，以下是可以安装MySQL主从服务器的Ansible代码：

---
- hosts: db_servers
become: true
tasks:
- name: Install MySQL server
yum:
name: mysql-server
state: present

- name: Start MySQL service
service:
name: mysqld
state: started
enabled: true

- name: Configure MySQL master
mysql_replication:
mode: "master"
login_host: "{{ inventory_hostname }}"
login_user: "{{ mysql_user }}"
login_password: "{{ mysql_password }}"
force: true

- name: Configure MySQL slave
mysql_replication:
mode: "slave"
login_host: "{{ inventory_hostname }}"
login_user: "{{ mysql_user }}"
login_password: "{{ mysql_password }}"
master_host: "{{ mysql_master_host }}"
master_user: "{{ mysql_master_user }}"
master_password: "{{ mysql_master_password }}"
master_port: "{{ mysql_master_port }}"
force: true

注意：这个Ansible代码只是一个范例，需要根据你的具体情况进行修改。另外，确保在运行之前，你已经设置好了MySQL的用户名和密码。
