docker 安装 nacos 1.1.X 并配置外部mysql数据库存储

￡神魔★判官ぃ 2023-06-19 02:26 14阅读 0赞

docker 安装请参考 : [Centos7 安装Docker设置开启自启 并解决常见报错问题][Centos7 _Docker_]

使用命令拉取nacos镜像

docker pull nacos/nacos-server:1.1.0

拉取完成后使用命令查看镜像

如果下载速度过慢可以参考切换163镜像 : [docker pull镜像速度慢的问题解决方法][docker pull]

docker images

创建nacos日志外部映射文件夹

mkdir -p /root/nacos/standalone-logs/

创建数据库 nacos-config 并该地址下的sql : [nacos-sql文件地址][nacos-sql]

创建nacos容器 并启动

docker run -d \
    -e TZ="Asia/Shanghai" \
    -e MODE=standalone \
    -e SPRING_DATASOURCE_PLATFORM=mysql \
    -e MYSQL_MASTER_SERVICE_HOST=192.168.101.11 \
    -e MYSQL_MASTER_SERVICE_PORT=3306 \
    -e MYSQL_MASTER_SERVICE_USER=root \
    -e MYSQL_MASTER_SERVICE_PASSWORD=root \
    -e MYSQL_MASTER_SERVICE_DB_NAME=nacos-config \
    -e MYSQL_SLAVE_SERVICE_HOST=192.168.101.11 \
    -p 8848:8848 \
    --expose=8848 \
    --name nacos \
    --restart=always \
    -v /root/nacos/standalone-logs/:/home/nacos/logs \
    nacos/nacos-server:1.1.0

docker start nacos

具体配置参数参考[官方文档][Link 1]，这里有个注意的是 `MYSQL_SLAVE_SERVICE_HOST `也需要配置

因为通过查看`nacos`容器内的 `config/application.properties `文件，会发现这此值未设置默认值，

所以会导致启动报错，容器启动不起来，这里可以与主数据库一致
