阿里云服务器中docker下安装nacos

1、拉镜像，版本查看：https://github.com/nacos-group/nacos-docker

docker pull nacos/nacos-server:1.1.4  //稳定版，无权限
docker pull nacos/nacos-server:1.3.1  //稳定版，有权限

2、创建目录

mkdir -p /home/dockerdata/nacos/logs
mkdir -p /home/dockerdata/nacos1.3.1/logs

3、运行镜像  默认账号密码：nacos/nacos

#1.1.4
docker run -d 
-e PREFER_HOST_MODE=ip 
-e MODE=standalone 
-e SPRING_DATASOURCE_PLATFORM=mysql 
-e MYSQL_MASTER_SERVICE_HOST=172.168.1.33 
-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 
-e MYSQL_SLAVE_SERVICE_HOST=172.168.1.33 
-e MYSQL_SLAVE_SERVICE_PORT=3306 
-v /home/dockerdata/nacos/logs:/home/nacos/logs 
-p 8848:8848 
--name nacos 
--restart=always 
nacos/nacos-server:1.1.4


  #1.3.1
docker run -d 
-e PREFER_HOST_MODE=ip 
-e MODE=standalone 
-e SPRING_DATASOURCE_PLATFORM=mysql 
-e MYSQL_SERVICE_HOST=172.168.1.33 
-e MYSQL_SERVICE_PORT=3306 
-e MYSQL_SERVICE_USER=root 
-e MYSQL_SERVICE_PASSWORD=root 
-e MYSQL_SERVICE_DB_NAME=nacos 
-e TIME_ZONE='Asia/Shanghai' 
-v /home/dockerdata/nacos1.3.1/logs:/home/nacos/logs 
-p 8848:8848 
--name nacos1.3.1 
--restart=always 
nacos/nacos-server:1.3.1

4、nacos初始化sql,需要先创建nacos数据库后，然后执行下面的sql

https://github.com/alibaba/nacos/blob/master/config/src/main/resources/META-INF/nacos-db.sql

1.1.4 升级1.3.1需要执行的脚本

ALTER TABLE `roles` ADD UNIQUE `uk_username_role` (`username`, `role`); CREATE TABLE permissions ( role varchar(50) NOT NULL, resource varchar(512) NOT NULL, action varchar(8) NOT NULL, constraint uk_role_permission UNIQUE (role,resource,action) ) ROW_FORMAT=DYNAMIC;

如果启动1.3.1报错，比如mysql时区异常，把conf配置文件弄到主机上

docker cp nacos1.3.1:/home/nacos/conf /home/dockerdata/nacos1.3.1 


#修改mysql的配置后


docker stop nacos1.3.1docker rm nacos1.3.1
docker run -d -e PREFER_HOST_MODE=ip 
-e MODE=standalone 
-e SPRING_DATASOURCE_PLATFORM=mysql 
-e MYSQL_SERVICE_HOST=172.168.1.33 
-e MYSQL_SERVICE_PORT=3306 -e MYSQL_SERVICE_USER=root 
-e MYSQL_SERVICE_PASSWORD=root -e MYSQL_SERVICE_DB_NAME=nacos 
-e TIME_ZONE='Asia/Shanghai' -v /home/dockerdata/nacos1.3.1/logs:/home/nacos/logs 
-v /home/dockerdata/nacos1.3.1/conf:/home/nacos/conf -p 8848:8848 
--name nacos1.3.1 --restart=always 
acos/nacos-server:1.3.1

5、访问nacos

http://ip:8848/nacos/

注意：一定要先打开数据库，在启动nacos 否则会报下面的错

No DataSource set

ERROR Application run failed

最后不要忘记更改阿里云安全组的配置规则 

如果还是访问不到建议查看防火墙是否开启

一、防火墙的状态。有时打开防火墙外部不能访问。

防火墙的命令：

查看防火墙状态

systemctl status firewalld

开启防火墙 

systemctl start firewalld

关闭防火墙

 systemctl stop firewalld

禁止开机启动防火墙 

systemctl disable firewalld.service

先用：

systemctl unmask firewalld.service

然后：

systemctl start firewalld.service

二、查看你的服务的端口号是否对外开放。
命令：
1.查询已经对外开放的端口

netstat -anp

2.查询指定端口是否已经开放

firewall-cmd --query-port=8848/tcp

返回yes/no。此时也有可能返回firewalld is not running，此时需要打开防火墙在开放端口。
开放端口号命令：
添加指定需要开放的端口：

firewall-cmd --add-port=8848/tcp --permanent

重载入添加的端口：

firewall-cmd --reload

查询指定端口是否开启成功：

firewall-cmd --query-port=8848/tcp
