先给出来官网,方便查阅信息:nacos官网
docker安装nacos,其实官方已经给出脚本了,而且给的还挺全。但就是太扯淡了,compose.yml中还带数据库了,也就是按他的那个,nacos容器启动了,还给你另起了mysql容器,给的挺全,有支持mysql5.7的脚本,有支持mysql8的脚本。不知道产品经理脑袋是不是被绿提过,就是不给你整合自己原有数据库的脚本,这不扯淡吗,我都要整合数据库了,我自己能没数据库吗,还用你再给我启个mysql容器?
你要是没有mysql数据库,直接用官方的就行了。我这里就直接给出整合自己原数据库的(但前提是,你自己必须先建好nacos数据库,并导入表,官网都有)。
1. 单机
单机和集群一样,也用 docker-compose.yml文件。
sudo mkdir -p /home/soft/nacos/
cd /home/soft/nacos
sudo vim nacos.yml
写入以下配置:
version: "3.9"
services:
nacos:
hostname: nacos
container_name: nacos
image: nacos/nacos-server:v1.4.5
volumes:
- /home/soft/nacos/logs:/home/nacos/logs
- /home/soft/nacos/custom.properties:/home/nacos/init.d/custom.properties
ports:
- "8848:8848"
- "9848:9848"
- "9555:9555"
environment:
PREFER_HOST_MODE: ip
MODE: standalone
SPRING_DATASOURCE_PLATFORM: mysql
MYSQL_SERVICE_HOST: 192.168.20.22
MYSQL_SERVICE_DB_NAME: nacos
MYSQL_SERVICE_PORT: 3306
MYSQL_SERVICE_USER: root

JVM_XMS: 256m

NACOS_AUTH_IDENTITY_KEY: nacos
NACOS_AUTH_IDENTITY_VALUE: nacos
# 2.0以上版本开启鉴权时要添加这个,可以改,位数这么多就行
# NACOS_AUTH_TOKEN=SecretKey012345678901234567890123456789012345678901234567890123456789
restart: always
## 如果没有自定义网络,下面的networks都可以不写
networks:
zrb_network:
ipv4_address: 192.168.20.30
## 已经自定义好的网络
networks:
zrb_network:
external: true
检查,启动:
sudo docker compose -f nacos.yml config -q
sudo docker compose -f nacos.yml up -d
2. 集群
集群也是一样的。
sudo mkdir -p /home/soft/nacos-cluster/
cd /home/soft/nacos
sudo vim nacos-cluster.yml
写入以下配置:
version: "3.9"
services:
nacos8848:
hostname: nacos8848
container_name: nacos8848
image: nacos/nacos-server:v1.4.5
