一.适配Oracle
可借鉴这两条博客：
也可拉取我的nacos进行搭建：清寒/nacos-all-oracle
主要的适配就是添加数据源，修改源码中的sql。
二.搭建Nacos集群。
修改完源码后，可使用命令对代码进行编译打包
mvn -Prelease-nacos -Dmaven.test.skip=true -Dpmd.skip=true -Drat.skip=true -Dcheckstyle.skip=true clean install -U
//解释
mvn \
-Prelease-nacos \ # 激活 release-nacos profile
-Dmaven.test.skip=true \ # 跳过测试
-Dpmd.skip=true \ # 跳过 PMD 代码检查
-Drat.skip=true \ # 跳过 Apache RAT 许可证检查
-Dcheckstyle.skip=true \ # 跳过代码风格检查
clean \ # 清理之前的构建
install \ # 安装到本地仓库
-U # 强制更新依赖注意：如果启动时不是使用指定配置文件的方式，需要先修改application.properties文件。
如果启动时想要使用外置的配置文件，则需先将代码中的application.properties文件注释，否则jar包内部的配置文件优先级会高于外部，导致外置配置不生效。（console和distribution下的配置文件都注释）
构建完成后，在nacos-distribution模块target目录下找到nacos-server.zip。
拿到压缩包，找个目录解压，如下：
本地启动时，进入bin目录的cmd窗口，执行命令：
# 单机模式
startup.cmd -m standalone
# 集群模式
startup.cmd -m cluster此处省略不表。
下面说一下Linux服务器中搭建nacos Dcoker集群的过程。
1.创建挂载目录
mkdir /usr/local/nacos
cd /usr/local/nacos
mkdir conf data logs
2.准备配置文件
application.properties内容，放在conf目录下

在conf目录下添加cluster.conf文件
##此处是我的虚拟机IP及nacos端口，你使用需要更换
192.168.187.129:31003
192.168.187.130:31003
192.168.187.131:31003在nacos目录下创建dockerfile文件
FROM openjdk:8-jdk
WORKDIR /usr/local/nacos
# 设置时区
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
# 环境变量
ENV MODE=cluster
ENV PREFER_HOST_MODE=ip
ENV NACOS_APPLICATION_PORT=31003
# 创建目录
RUN mkdir -p /usr/local/nacos/logs \
&& mkdir -p /usr/local/nacos/conf \
&& mkdir -p /usr/local/nacos/data
# 复制 jar 包
COPY nacos-server.jar /usr/local/nacos/nacos-server.jar
# 健康检查

"-Dnacos.core.member.lookup.type=file", \
"-jar", \
"/usr/local/nacos/nacos-server.jar", \
"--spring.config.location=classpath:/,file:/usr/local/nacos/conf/"]将nacos-server.jar包上传至/usr/local/nacos目录下
操作完后，大体目录：
3.执行命令构建镜像并跑容器
# 构建镜像
docker build -t nacos-server:latest .
# 节点1 (192.168.187.130)
docker run -d \
--name nacos \
--restart always \
--network host \
-v /usr/local/nacos/conf:/usr/local/nacos/conf \
-v /usr/local/nacos/logs:/usr/local/nacos/logs \
-e MODE=cluster \
-e PREFER_HOST_MODE=ip \
-e NACOS_SERVER_IP=192.168.187.130 \
-e SPRING_DATASOURCE_PLATFORM=oracle \
-e JVM_XMS=512m \
-e JVM_XMX=512m \
nacos-server:latest等待一会通过命令docker logs -ft nacos查看日志。
访问页面，可以看到集群搭建好，当前节点已被拉起。
使用相同的方式拉起其他两台节点，集群就搭建好了。
# 安装 openssh-clients
yum install -y openssh-clients
# 如果需要 SSH 服务器
yum install -y openssh-server
#可以使用scp命令将文件在服务器间进行传送
# 1. 从本地复制到远程
scp 本地文件 用户名@远程主机:远程路径
# 2. 从远程复制到本地
scp 用户名@远程主机:远程文件 本地路径
# 3. 复制目录（加 -r 参数）
scp -r 本地目录 用户名@远程主机:远程路径
###示范
# 1. 复制单个文件到远程服务器
scp /path/to/local/file.txt root@192.168.1.100:/path/to/remote/
# 2. 复制远程文件到本地
scp root@192.168.1.100:/path/to/remote/file.txt /path/to/local/
# 3. 复制整个目录到远程服务器
scp -r /path/to/local/dir root@192.168.1.100:/path/to/remote/
# 4. 复制远程目录到本地
scp -r root@192.168.1.100:/path/to/remote/dir /path/to/local/
# 5. 指定端口号（如果不是默认22端口）
scp -P 2222 file.txt root@192.168.1.100:/path/to/remote/
# 6. 保持文件属性
scp -p file.txt root@192.168.1.100:/path/to/remote/
# 7. 显示详细传输信息
scp -v file.txt root@192.168.1.100:/path/to/remote/
三.搭建nginx实现负载均衡
1.创建新的目录结构
mkdir -p /usr/local/nginx/{conf,conf.d,logs,html}2.修改配置文件
cat > /usr/local/nginx/conf/nginx.conf << 'EOF'
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log notice;
pid /var/run/nginx.pid;

docker pull nginx:latest4.启动nginx容器
docker run -d \
--name nginx \
--restart always \
--network host \
-v /usr/local/nginx/conf/nginx.conf:/etc/nginx/nginx.conf:ro \
-v /usr/local/nginx/logs:/var/log/nginx \
-v /usr/local/nginx/html:/usr/share/nginx/html:ro \
nginx:latest页面上进行验证，成功
