nacos单机版安装

环境:
OS:Centos 7
nacos:2.5.2

mysql:5.7
jdk:21.0.4

 

1.下载
地址地址
https://github.com/alibaba/nacos/releases/tag/2.5.2
下载介质
nacos-server-2.5.2.tar.gz

 

2.解压安装
每个机器都要执行如下操作
[root@master soft]# tar -xvf nacos-server-2.5.2.tar.gz
[root@master soft]# mv nacos /opt/

 

3.创建数据库
我这里使用一个节点上安装mysql,也可以单独使用一个机器安装mysql
[root@node2 opt]# /opt/mysql57/bin/mysql -h 192.168.1.135 -uroot -pmysql
mysql> create database db_nacos;
Query OK, 1 row affected (0.00 sec)

4.执行SQL
/opt/mysql57/bin/mysql -h 192.168.1.135 -uroot -pmysql

mysql>use db_nacos;
mysql>source /opt/nacos/conf/mysql-schema.sql

 

5.账号授权
grant all privileges on *.* to 'root'@'%' identified by 'mysql' with grant option;
flush privileges;

 

6.修改配置文件
vi /opt/nacos/conf/application.properties

### Connect URL of DB:
db.url.0=jdbc:mysql://192.168.1.135:13306/db_nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&u
seUnicode=true&useSSL=false&serverTimezone=Asia/Shanghai
db.user.0=root
db.password.0=mysql

spring.datasource.platform=mysql
db.num=1

 

7.修改启动文件
根据机器性能适当修改分配的内存

vi /opt/nacos/bin/startup.sh#===========================================================================================
# JVM Configuration
#===========================================================================================
if [[ "${MODE}" == "standalone" ]]; thenJAVA_OPT="${JAVA_OPT} ${CUSTOM_NACOS_MEMORY:- -Xms512m -Xmx512m -Xmn256m}"JAVA_OPT="${JAVA_OPT} -Dnacos.standalone=true"

 

8.启动nacos
每个节点都启动
cd /opt/nacos/bin
sh startup.sh -m standalone #以单机方式启动

查看日志
more /opt/nacos/logs/startup.log

启动成功会有如下日志输出
2025-11-20 14:14:35,486 INFO Tomcat started on port(s): 8848 (http) with context path '/nacos'
2025-11-20 14:14:35,578 INFO No TaskScheduler/ScheduledExecutorService bean found for scheduled processing
2025-11-20 14:14:35,692 INFO Nacos started successfully in stand alone mode. use external storage

 

9.访问nacos
http://192.168.1.134:8848/nacos
账号密码
nacos/nacos

10.配置密码验证
10.1.停掉nacos
/opt/nacos/bin/shutdown.sh

 

10.2.修改配置
vi /opt/nacos/conf/application.properties

 

nacos.core.auth.enabled=true
nacos.core.auth.server.identity.key= nacos
nacos.core.auth.server.identity.value= nacos
nacos.core.auth.plugin.nacos.token.secret.key=bmFjb3NuYWNvczEyMzQ1Njc4OW5hY29zbmFjb3MxMjM=

bmFjb3NuYWNvczEyMzQ1Njc4OW5hY29zbmFjb3MxMjM=
是如下字符串的base64编码,在线编码工具:https://base64.us/?spm=5238cd80.3df4f17.0.0.491a7abfRBBTYa
nacosnacos123456789nacosnacos123

 

10.3启动
/opt/nacos/bin/startup.sh -m standalone

再次登录设置nacos的初始化密码,我这里设置为nacos
