nacos集群安装

news 2026/5/12 21:42:22

环境
OS:Centos 7
nacos:2.5.2

三台集群组成集群
192.168.1.108
192.168.1.105
192.168.1.106

安装所需要得条件配置
1.jdk安装的是:21.0.6
2.maven安装的是:3.9.9
3.mysql安装的是:mysql-5.7.43

1.下载地址
https://github.com/alibaba/nacos/releases/tag/2.5.2
我这里下载的是2.5.2版本,介质如下:
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 192.168.1.106 -uroot -pmysql
mysql> create database db_nacos;
Query OK, 1 row affected (0.00 sec)

4.执行SQL
/opt/mysql57/bin/mysql -h 192.168.1.106 -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://192.168.1.106:3306/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

拷贝配置文件到其他另外2个节点
scp /opt/nacos/conf/application.properties root@192.168.1.105:/opt/nacos/conf/
scp /opt/nacos/conf/application.properties root@192.168.1.106:/opt/nacos/conf/

7.集群化配置
[root@master conf]#cd /opt/nacos/conf/
[root@master conf]#cp cluster.conf.example cluster.conf

vi cluster.conf
#it is ip
#example
192.168.1.108:8848
192.168.1.105:8848
192.168.1.106:8848

将该配置文件拷贝到其他机器
scp /opt/nacos/conf/cluster.conf root@192.168.1.105:/opt/nacos/conf/
scp /opt/nacos/conf/cluster.conf root@192.168.1.106:/opt/nacos/conf/

8.修改启动文件
根据机器性能适当修改,我这里修改成1GB
