linux之nacos安装

找到nacos-server-2.0.1.tar.gz 点击进行下载，下载完成后上传到服务器中。
方式二、使用wget命令下载
也有两种方式：第一种下载速度较慢

1. wget https://github.com/alibaba/nacos/releases/download/2.0.1/nacos-server-2.0.1.tar.gz
2. wget https://download.fastgit.org/alibaba/nacos/releases/download/2.0.1/nacos-server-2.0.1.tar.gz

复制代码

  

  

1. vim application.properties

复制代码

编辑端口号，注意端口号必要大于5001

1. ### Default web context path:
2. server.servlet.contextPath=/nacos
3. ### Default web server port:
4. server.port=9001

复制代码

解开数据库的表明

1. ### If use MySQL as datasource:
2. spring.datasource.platform=mysql
4. ### Count of DB:
5. db.num=1

复制代码

编辑数据库连接的所在，用于连接mysql数据库。账号和暗码为mysql数据库暗码。注意此处的mysql.xxx.tech:3306/nacos nacos为此前创建的数据库名。

1. ### Connect URL of DB:
2. db.url.0=jdbc:mysql://mysql.xxx.tech:3306/nacos_prod?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
3. db.user.0=nacos
4. db.password.0=nacos

复制代码

1. sh startup.sh
3. -m standalone

复制代码

集群模式

1. sh startup.sh

复制代码

ps:若是配置集群的话，必要修改cluster.conf.example
在里边添加其他节点的nacos的IP
  
解决问题：
方式一：查看nacos进程是否启动了多个进程，kill所有进程，再启动nacos

1. #查看nacos进程
2. ps aux|grep nacos
3. #kill进程
4. kill 进程id

复制代码

方式二：由于端口号的问题，在第四步，编辑端口号，注意端口号必要大于5001。并保证该端口被开放,再启动nacos

1. #查询指定端口是否已开启
2. firewall-cmd --query-port=9001/tcp
3. #添加指定需要开放的端口：
4. firewall-cmd --add-port=9001/tcp --permanent
5. #重启防火墙
6. firewall-cmd --reload
