环境介绍

操作系统	Kylin Linux Advanced Server V10 (Lance)	Kylin Linux Advanced Server V10 (Lance)	Kylin Linux Advanced Server V10 (Lance)
内核版本	Linux 4.19.90-52.22.v2207.ky10.aarch64	Linux 4.19.90-52.22.v2207.ky10.aarch64	Linux 4.19.90-52.22.v2207.ky10.aarch64

Nacos	2.4.2	2.4.2	2.4.2

使用外置数据源

生产使用建议至少主备模式，或者采用高可用数据库。

nacos集群部署官方文档

1. 安装JDK

# 解压
# 下载地址 https://d.injdk.cn/download/oraclejdk/8/jdk-8u381-linux-aarch64.tar.gz
tar -zxvf jdk-8u381-linux-aarch64.tar.gz

# 创建文件夹
mkdir -p /usr/local/java

# 移动目录
mv jdk1.8.0_381 /usr/local/java

# 配置环境变量
vi /etc/profile.d/jdk.sh

#!/bin/bash
export JAVA_HOME=/usr/local/java/jdk1.8.0_381
export PATH=${PATH}:${JAVA_HOME}/bin

# 启用
source /etc/profile.d/jdk.sh

# 验证
java -version

2. 下载安装Nacos

# 下载地址
# yum install -y wget
wget https://github.com/alibaba/nacos/releases/download/2.4.2/nacos-server-2.4.2.tar.gz


# 移动
mv nacos /usr/local

# 修改配置文件
cd /usr/local/nacos/conf
cp /usr/local/nacos/conf/cluster.conf.example /usr/local/nacos/conf/cluster.conf

# 修改配置
192.168.31.82:8848
192.168.31.83:8848
192.168.31.84:8848


# 导入数据库脚本


# 修改配置文件application.properties

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

### Connect URL of DB:
db.url.0=jdbc:mysql://IP:端口/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=root
db.password.0=yuanfang_2024

3. 启动服务

3.1 准备数据库表

数据库表

如果访问不了复制下面sql即可前提数据库中得有nacos这个数据库，如果没有则创建

4. 安装nginx

4.1 安装前提(可选)

# 检查电脑是否安装了 pcre-config openssl 如果没有则安装
# 下载pcre(其他)
wget http://downloads.sourceforge.net/project/pcre/pcre/8.37/pcre-8.37.tar.gz

# 解压
tar -zxvf pcre-8.37.tar.gz

# 进入目录
cd pcre-8.37

# 编译安装
./configure
make install

# 检测是否安装成功
pcre-config --version

# 下载 openssl(其他)
https://github.com/openssl/openssl/releases/download/openssl-3.2.1/openssl-3.2.1.tar.gz

# 解压
tar -zxvf openssl-3.2.1.tar.gz

# 进入目录
cd openssl-3.2.1

# 编译安装
./config 

make install

# 安装zlib
yum -y install zlib zlib-devel libtool

4.2 安装nginx

# 官方地址
https://nginx.org/en/download.html

# 下载
mkdir -p /opt/software/nginx && cd /opt/software/nginx
wget https://nginx.org/download/nginx-1.26.2.tar.gz

# 解压
tar -zxvf nginx-1.26.2.tar.gz

# 进入到nginx目录编译安装
cd nginx-1.26.2

# 编译安装
