Nacos安装和配置

Nacos 注册中心 配置中心 软件安装
分布式系统
发布日期:   2021-02-25

我们这里是在Centos7上进行的操作；首先在nacos的github 上下载安装包，直接选择最新的releases版本即可，如：nacos-server-1.4.1.tar.gz ；windows系统的话直接下载zip包安解压即可。

如果想要自己构建，直接下载源码使用maven打包(mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U)即可。

配置jdk（如果没有的话）

注意需要安装和配置Java环境（使用yum快速安装和配置jdk yum install java-1.8.0-openjdk.x86_64 ）

# 查看已有jdk版本
yum list java*

# 这里直接安装jdk8
yum install java-1.8.0-openjdk.x86_64 -y
yum install java-1.8.0-openjdk-devel.x86_64 -y

单机版部署

非常简单直接解压启动即可

tar -xvf nacos-server-1.4.1.tar.gz
cd nacos
sh startup.sh -m standalone

启动成功后访问http://你的服务器IP:8848/nacos/index.html 即可，默认是没有密码的，进去过后可以通过修改密码进行设置。

如果开启了防火墙，要么通过如下命令停止防火墙

systemctl disable firewalld
systemctl stop firewalld

或者设置防火墙开放端口

firewall-cmd --zone=public --add-port=8848/tcp --permanent
firewall-cmd --reload

查看防火墙开放端口：firewall-cmd –list-port
停止Nacos服务 sh bin/shutdown.sh
注意nacos默认配置需要的jvm内存是2G,因此如果服务器内存小的话，需要去修改启动命令中设置的jvm的内存配置

集群版部署

解压安装包

tar -xvf nacos-server-1.4.1.tar.gz
cd nacos
# 拷贝集群配置文件
cp conf/cluster.conf.example conf/cluster.conf
vi conf/cluster.conf

在cluster上添加服务节点

192.168.0.113:8848
192.168.0.114:8848
192.168.0.115:8848

修改conf目录下的application.properties中数据库配置

### If use MySQL as datasource:
spring.datasource.platform=mysql

### Count of DB:
db.num=1

### Connect URL of DB:
db.url.0=jdbc:mysql://192.168.56.103:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=root
db.password.0=123456

创建数据库

下面是SQL语句(压缩包里面有)

INSERT INTO roles (username, role) VALUES ('nacos', 'ROLE_ADMIN');

注意这里的密码是需要加密的；使用的是spring-boot-starter-security的new BCryptPasswordEncoder().encode(“nacos”)

启动修改好配置后，依次启动每个nacos服务
