1.初始化数据库表

MySQL

mysql -V
# 结果
mysql  Ver 8.0.33 for macos13 on x86_64 (MySQL Community Server - GPL)

cmd命令行客户端

# 密码建议在下一行输入
mysql -h localhost -P 3306 -u root -pmysql -h localhost -P 3306 -u root -p12345678mysql -h localhost -P 3306 -u nacos -pnacos

创建用户与授权

https://dev.mysql.com/doc/refman/8.0/en/create-user.html
https://dev.mysql.com/doc/refman/8.0/en/grant.html

CREATE USER 'username'@'host' IDENTIFIED BY 'password';
# 创建用户
CREATE USER 'nacos'@'localhost' IDENTIFIED BY 'nacos';# 授权
GRANT ALL ON *.* TO 'nacos'@'localhost';# 删除用户
DROP USER 'nacos'@'127.0.0.1';

创建数据库

https://dev.mysql.com/doc/refman/8.0/en/create-database.html

CREATE DATABASE IF NOT EXISTS nacosDEFAULT CHARACTER SET = utf8mb4DEFAULT COLLATE = utf8mb4_bin;# 删除数据库
DROP DATABASE nacos;

创建数据表

https://dev.mysql.com/doc/refman/8.0/en/create-table.html

# 切换数据库
USE nacos;# 创建数据表
# nacos/conf/mysql-schema.sql

2.启动Nacos服务器

1.增加nacos/conf/application.properties的数据源配置

#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource:
### Deprecated configuration property, it is recommended to use `spring.sql.init.platform` replaced.
# spring.datasource.platform=mysql
# spring.sql.init.platform=mysql
spring.sql.init.platform=mysql### Count of DB:
# db.num=1
db.num=1### Connect URL of DB:
# 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=nacos
# db.password.0=nacos
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=nacos
db.password.0=nacos

2.启动Nacos服务器

unzip nacos-server-2.2.3.zip
# 移动文件夹
sudo mv nacos-server-2.2.3 /usr/localcd /usr/local
# 创建软链接
sudo ln -s nacos-server-2.2.3 nacos
# 变更软链接的所有者和分组
sudo chown -R feimen:staff nacos# 启动独立服务器
cd nacos
sh bin/startup.sh -m standalone
