# 1、从官网下载nacos压缩包：nacos-server-2.2.3.tar.gz
https://github.com/alibaba/nacos/releases
 
# 2、上传到服务器并解压
tar -zxvf nacos-server-2.2.3.tar.gz
 
# 3、手动创建数据库，并执行脚本
/usr/local/nacos/conf/nacos-mysql.sql
 
# 4、修改application.properties配置文件
db.url.0=jdbc:mysql://localhost:3307/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
db.user.0=ancoda
db.password.0=123456
 
# 5、进入bin目录，启动nacos
./startup.sh -m standalone
 
# 6、查看日志
/usr/local/nacos/nacos/logs的nacos.log
 
# 访问nacos服务
