1:下载nacos安装包
方式一、进入官网下载压缩包
官网地址
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
wget https://github.com/alibaba/nacos/releases/download/2.0.1/nacos-server-2.0.1.tar.gz
wget https://download.fastgit.org/alibaba/nacos/releases/download/2.0.1/nacos-server-2.0.1.tar.gz
2:创建mysql数据库
如下的操作步骤
A:在解压号的nacos文件夹下找到config文件夹
B:进入config文件夹，找到nacos-mysql.sql文件
C:将nacos-mysql.sql文件下载到本地，本地使用Navicat连接上mysql
D:使用Navicat在mysql中创建名为nacos的数据库，注意数据库名后面会用上.
3:修改数据库配置
进入到conf目录修改application.properties
vim application.properties
编辑端口号，注意端口号需要大于5001
### Default web context path:
server.servlet.contextPath=/nacos
### Default web server port:
server.port=9001
解开数据库的注释
### If use MySQL as datasource:
spring.datasource.platform=mysql### Count of DB:
db.num=1
编辑数据库连接的地址，用于连接mysql数据库。账号和密码为mysql数据库密码。注意此处的mysql.xxx.tech:3306/nacos nacos为此前创建的数据库名。
### Connect URL of DB:
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
db.user.0=nacos
db.password.0=nacos
完整配置如下

5:期间遇到的问题
1.No DataSource set
问题描述：
问题原因：没有找到数据源，一般情况是application.properties中，配置的mysq连接有问题。
解决问题：核对第4步中的数据库配置，注意域名、数据库、mysql的账号密码是否正确。
2.java.io.IOException: Failed to bind
问题描述：
com.alibaba.nacos.core.distributed.raft.exception.JRaftException: java.io.IOException: Failed to bind
问题原因：绑定失败
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
#查看nacos进程
ps aux|grep nacos
#kill进程
kill 进程id
方式二：由于端口号的问题，在第四步，编辑端口号，注意端口号需要大于5001。并保证该端口被开放,再启动nacos
#查询指定端口是否已开启
firewall-cmd --query-port=9001/tcp
#添加指定需要开放的端口：
firewall-cmd --add-port=9001/tcp --permanent
#重启防火墙
firewall-cmd --reload
