Docker内部署单机nacos使用mysql8.0存储

Docker下载镜像

docker pull nacos/nacos-server
笔者下载时已经到1.3.2 其中mysqljar已经更新至8.0.16

创建数据库

create database nacos_config
https://github.com/alibaba/nacos/blob/master/config/src/main/resources/META-INF/nacos-db.sql
复制sql并执行

创建nacos容器1

docker run -d \
-e PREFER_HOST_MODE=hostname \
-e MODE=standalone \
-e SPRING_DATASOURCE_PLATFORM=mysql \
-e MYSQL_MASTER_SERVICE_HOST=数据库ip \
-e MYSQL_MASTER_SERVICE_PORT=数据库端口 \
-e MYSQL_MASTER_SERVICE_USER=用户名 \
-e MYSQL_MASTER_SERVICE_PASSWORD=密码 \
-e MYSQL_MASTER_SERVICE_DB_NAME=对应的数据库名 \
-e MYSQL_SLAVE_SERVICE_HOST=从数据库ip \
-p 8848:8848 \
--name nacos-sa-mysql \
--restart=always \
nacos/nacos-server

创建nacos容器2

如果创建nacos容器1docker命令报错,可使用下面命令创建容器

mkdir -p /home/nacos/logs/                      #新建logs目录
mkdir -p /home/nacos/init.d/          
vim /home/nacos/init.d/custom.properties        #修改配置文件

修改容器

docker exec -it nacos bash
#进入nacos容器：
docker exec -it nacos bash 
#进入conf文件夹
cd conf
#修改配置参数
vim application.properties

# spring
server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}
server.contextPath=/nacos

### The auth system to use, currently only 'nacos' is supported:
nacos.core.auth.system.type=${NACOS_AUTH_SYSTEM_TYPE:nacos}


### The token expiration in seconds:
nacos.core.auth.default.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000}

### The default token:
nacos.core.auth.default.token.secret.key=${NACOS_AUTH_TOKEN:SecretKey012345678901234567890123456789012345678901234567890123456789}

### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
nacos.core.auth.caching.enabled=${NACOS_AUTH_CACHE_ENABLE:false}

server.tomcat.accesslog.enabled=${TOMCAT_ACCESSLOG_ENABLED:false}
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D
# default current work dir

## spring security config
### turn off security

修改spring.datasource.platform=
db.url.0=
db.url.1不使用可注释
Mysql8.0 需要指定时区serverTimezone=GMT%2B8
然后 ：wq 保存退出；

exit命令退出容器;
docker restart nacos命令重启容器;

http://ip/8848/nacos访问,默认nacos/nacos,并创建用户

查看数据库,连接成功
