nacos/nacos-server:v2.2.0Nginx 配置
1- 拉取镜像
docker pull nginx2- 准备需要挂载的文件
# 运行一个 nginx 镜像
docker run -it -d --nametemp -p 8080:80 nginx
# 拷贝文件到主机用于后面的挂载
docker cp temp:/usr/share/nginx/html ./
docker cp temp:/etc/nginx ./3- 编辑配置文件
vim ./nginx/nginx.conf在 http 中添加 nacos 配置具体参考图片
#下面是 Naocs 集群的配置
upstream nacoscluster {server 192.168.3.211:8848;server 192.168.3.212:8848;server 192.168.3.213:8848;
}
server {listen 8848; # 此处的 8848 可自定义server_name 192.168.3.208;location /nacos/ { proxy_pass http://nacoscluster/nacos/;}
}在 http 上一行 添加 nacosGrpc 配置Naocs 2.x 版本之前无需添加下面的配置具体参考图片
# 下面是 Nacos 的集群的配置
stream {upstream nacosGrpc {server 192.168.3.211:9848;server 192.168.3.212:9848;server 192.168.3.213:9848;}server {listen 9848; # 此处的 9848 在自定义基础上加1000即 8848 1000proxy_pass nacosGrpc;}
}4- 运行镜像
注意此处一定要将 nacos 的访问端口暴露出去我的访问端口是配置文件中自定义的 8848
docker run -it -d --namenacos-nginx --restartalways -p 18008:80 -p 8848:8848 -v ./content:/usr/share/nginx/html -v ./nginx:/etc/nginx nginx成功访问
访问地址http://192.168.3.208:8848/nacos/ Nacos 报错总结
docker 启动 nacos 报错
报错信息Error creating bean with name ‘memoryMonitor’ defined in URL [jar:file:/home/nacos/target/nacos-server
报错信息ErrMsg:Nacos Server did not start because dumpservice bean construction failure :No DataSource set 两种解决办法 nacos 启动失败是因为 mysql 没有被唤醒我们可以尝试用数据库连接工具连接 mysql 从而唤醒mysql最后重启 nacos 即可解决问题。 指定加载的先后顺序只有当 mysql 健康后才开始运行 nacos,需要我们在 nacos 中添加下面的脚本 healthcheck:test: curl --fail http://192.168.3.220:18848/nacos/actuator/health || exit 1interval: 10stimeout: 5sretries: 3推荐使用第二种解决办法为 MySQL 进行检查Nacos 只有在 MySQL 健康检查通过后才开始启动
