直接使用bin目录下的脚本来启动和关闭
默认可以直接启动
注意：单机模式需要加上参数 -m standalone
$ bash bin/startup.sh -m standalone
/usr/lib/jvm/java-11-openjdk-amd64/bin/java -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xlog:gc*:file=/root/nacos/logs/nacos_gc.log:time,tags:filecount=10,filesize=100m -Dloader.path=/root/nacos/plugins,/root/nacos/plugins/health,/root/nacos/plugins/cmdb,/root/nacos/plugins/selector -Dnacos.home=/root/nacos -jar /root/nacos/target/nacos-server.jar --spring.config.additional-location=file:/root/nacos/conf/ --logging.config=/root/nacos/conf/nacos-logback.xml --server.max-http-header-size=524288

查看日志，出现了 Nacos started successfully in stand alone mode. use embedded storage 表示启动成功
然后直接访问 <IP>:8848/nacos
直接就进来了，因为默认是不开启认证的
开启认证
关闭服务
$ bash bin/shutdown.sh

Send shutdown request to nacosServer(240122) OK
修改配置文件
vim conf/application.properties
#修改下面这几个选项
### If turn on auth system:
nacos.core.auth.enabled=true
### Since 1.4.1, worked when nacos.core.auth.enabled=true and nacos.core.auth.enable.userAgentAuthWhite=false.
### The two properties is the white list for auth and used by identity the request from other server.
nacos.core.auth.server.identity.key=abc
nacos.core.auth.server.identity.value=111
### worked when nacos.core.auth.system.type=nacos
### The token expiration in seconds:
nacos.core.auth.plugin.nacos.token.cache.enable=true
nacos.core.auth.plugin.nacos.token.expire.seconds=18000
### The default token (Base64 String):
nacos.core.auth.plugin.nacos.token.secret.key=MTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExCg==
然后再重新启动
$ bash bin/startup.sh -m standalone
/usr/lib/jvm/java-11-openjdk-amd64/bin/java -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xlog:gc*:file=/root/nacos/logs/nacos_gc.log:time,tags:filecount=10,filesize=100m -Dloader.path=/root/nacos/plugins,/root/nacos/plugins/health,/root/nacos/plugins/cmdb,/root/nacos/plugins/selector -Dnacos.home=/root/nacos -jar /root/nacos/target/nacos-server.jar --spring.config.additional-location=file:/root/nacos/conf/ --logging.config=/root/nacos/conf/nacos-logback.xml --server.max-http-header-size=524288
nacos is starting with standalone
nacos is starting. you can check the /root/nacos/logs/start.out
用户名是nacos，然后密码随便填，你写的什么密码，那密码就会被设置成什么
配置外部数据库
这里使用docker运行测试数据库
services:
mysql:
image: mysql:8
container_name: mysql
ports:
- 3306:3306
restart: always
user: '0'
volumes:
- ./db:/var/lib/mysql
- /usr/share/zoneinfo/Asia/Shanghai:/etc/localtime
environment:
MYSQL_ROOT_PASSWORD: 111111
#允许空密码
MYSQL_ALLOW_EMPTY_PASSWORD: no
#新建数据库
MYSQL_DATABASE: nacos
#新建用户
MYSQL_USER: admin
#设置用户密码
MYSQL_PASSWORD: 111111
这里会创建一个nacos数据库
导入表
mysql -h10.1.0.108 -uroot -p111111
mysql> GRANT ALL PRIVILEGES ON nacos.* TO 'admin'@'%';
Query OK, 0 rows affected (0.01 sec)
mysql> exit
Bye
mysql -h10.1.0.108 -uadmin -p111111
mysql> use nacos
Database changed
mysql> show tables;
Empty set (0.00 sec)
# 执行脚本
mysql> source /root/nacos/conf/mysql-schema.sql
Query OK, 0 rows affected, 3 warnings (0.03 sec)
Query OK, 0 rows affected, 1 warning (0.02 sec)
Query OK, 0 rows affected, 4 warnings (0.01 sec)
Query OK, 0 rows affected, 9 warnings (0.01 sec)
Query OK, 0 rows affected, 4 warnings (0.02 sec)

配置nacos
vim conf/application.properties
#修改下面这几个选项
spring.sql.init.platform=mysql
### Count of DB:
db.num=1
### Connect URL of DB:
db.url.0=jdbc:mysql://10.1.0.108:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=Asia/Shanghai
db.user.0=admin
db.password.0=111111
再次启动
bash bin/startup.sh -m standalone
