Nacos-server 2.2.3 安装配置

网址:https://github.com/alibaba/nacos/releases
下载链接 https://github.com/alibaba/nacos/releases/download/2.2.3/nacos-server-2.2.3.tar.gz
下载建议使用迅雷下载(p2p),使用网页下载会经常失败

1.ftp上传,启动nacos,关闭nacos

# /usr/local/software/nacos-server-2.2.3.tar.gz
# 解压
tar -zxvf nacos-server-2.2.3.tar.gz
# 解压后同级目录下有nacos
cd /usr/local/software/nacos/bin
# 下面有四个脚本 shutdown.cmd  shutdown.sh  startup.cmd  startup.sh # *.cmd为window执行,*.sh为linux
./startup.sh -m standalone
# ps 也可以直接修改vi startup.sh 修改MODE="standalone"
./shutdown.sh # 关闭退出

2.开启nacos auth

数据库安装配置(省略),创建数据库nacos并运行sql文件
/usr/local/software/nacos/conf/mysql-schema.sql

vi /usr/local/software/nacos/conf/application.properties
# 修改如下内容
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=root
db.password.0=root
### If turn on auth system:
nacos.core.auth.enabled=true
# authkey authvalue secret.key 自定义
nacos.core.auth.server.identity.key=authkey
nacos.core.auth.server.identity.value=authvalue
nacos.core.auth.plugin.nacos.token.secret.key=axjsoijkxo()_@(!#*(@&#(*!&$#&)!*(@)#*)sxaxs*)#!*@_


# 保存退出,并启动nacos
# PS:登陆 http://IP:8848/nacos(初始化密码/账户nacos/nacos),记得修改密码
