阿里雲服務器中docker下安裝nacos

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

docker pull nacos/nacos-server:1.1.4  //穩定版，無權限
docker pull nacos/nacos-server:1.3.1  //穩定版，有權限

2、創建目錄

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

3、運行鏡像  默認賬號密碼：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,需要先創建nacos數據庫后，然后執行下面的sql

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

1.1.4 升級1.3.1需要執行的腳本

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;

如果啟動1.3.1報錯，比如mysql時區異常，把conf配置文件弄到主機上

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 \nacos/nacos-server:1.3.1

5、訪問nacos

http://ip:8848/nacos/

注意：一定要先打開數據庫，在啟動nacos 否則會報下面的錯

No DataSource set

最后不要忘記更改阿里雲安全組的配置規則 

 

 

如果還是訪問不到建議查看防火牆是否開啟

一、防火牆的狀態。有時打開防火牆外部不能訪問。

防火牆的命令：

查看防火牆狀態

systemctl status firewalld

開啟防火牆 

systemctl start firewalld

關閉防火牆

 systemctl stop firewalld

 

禁止開機啟動防火牆 

systemctl disable firewalld.service

 

先用：

systemctl unmask firewalld.service

然后：

systemctl start firewalld.service

 

二、查看你的服務的端口號是否對外開放。
命令：
1.查詢已經對外開放的端口

netstat -anp

2.查詢指定端口是否已經開放

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

返回yes/no。此時也有可能返回firewalld is not running，此時需要打開防火牆在開放端口。
開放端口號命令：
添加指定需要開放的端口：

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

重載入添加的端口：

firewall-cmd --reload

 

查詢指定端口是否開啟成功：

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