搭建nacos集群 + ngnix反向代理

1.安装环境:
seata:1.4.1
#版本说明, nacos 1.4.1之前会有mysql版本兼容问题,需要手动改mysql版本. 1.4.1解决了此问题
nacos:1.4.1
jdk: 1.8 +
maven: 3.6.3

服务器地址:
server1:192.168.92.128:8848 -->nacos
server1:192.168.92.129:8848 -->nacos
server1:192.168.92.130:8848 -->nacos
server1:192.168.92.130 -->ningx

2.搭建server1–>nacos ,路径: /usr/local/
安装之前先安装JDKhttps://blog.youkuaiyun.com/weixin_41478499/article/details/115179358
MAVENhttps://blog.youkuaiyun.com/weixin_41478499/article/details/115180251

下载nacos

[root@dxm31 nacos]# wget https://github.com/alibaba/nacos/releases/download/1.4.1/nacos-server-1.4.1.tar.gz

解压

[root@localhost local]# tar -zxvf nacos-server-1.4.1.tar.gz 

解压完成删除安装包

[root@localhost local]# rm nacos-server-1.4.1.tar.gz 
rm：是否删除普通文件 "nacos-server-1.4.0.tar.gz"？y

初始化 nacos 必须的数据库表并配置,sql位置

[root@localhost conf]# vi /usr/local/nacos/conf/nacos-mysql.sql
