10.变量配置
/home/ansible/roles/nacos/defaults的main.yml文件中配置
nacos_version: "2.4.0"
plaintext_password: xxxxxxxx
# 控制节点nacos安装包上传路径
nacos_package_path: /opt/nacos/nacos-server-{{nacos_version}}.tar.gz

sql_file_path: /opt/nacos/mysql-schema.sql
sql_file_dest_path: /online/nacos/mysql-schema.sql
# 集群文件路径配置
cluster_conf_dest_path: /online/nacos/conf/cluster.conf
# 数据库及密钥文件
application_properties_path: /opt/nacos/application.properties
application_properties_dest_path: /online/nacos/conf/application.properties
#python虚拟路径
python_venv_path: /online/python/venv
#python路径
python_path: /usr/bin/python3
# java路径
java_home: /usr/lib/jvm/java-8-openjdk-amd64
# logback文件
logback_path: /opt/nacos/nacos-logback.xml
logback_dest_path: /online/nacos/conf/nacos-logback.xml
11.配置nacos.yml
/home/ansible/playbooks/dev/middleware中配置nacos.yml
---
- name: Install and configure Nacos cluster
hosts: nacos
become: yes
roles:
- role: nacos
cluster_conf_j2_file: "{{ hostvars[inventory_hostname]['cluster_conf_j2_file'] }}" # 对应的配置文件
vars:
login_user: "root"
login_password: "xxxxx"
mysql_host: 10.xxx.10.xx
mysql_port: 3306
new_user_password: "xxxxxxxx" #nacos管理页面
配置完上述项，在/home/ansible/playbooks/dev/middleware中，执行
ansible-playbook nacos.yml
