linux 配置nacos遇见的问题及解决办法

news2024/11/24 4:41:51

本次的集群是启动一个服务的三个不同端口，配置如下：

一.application.properties

加上下列配置，目的是使用自己的mysql数据库：

spring.datasource.platform=mysql

db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?serverTimezone=Asia/Shanghai&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=root

注意：属性serverTimezone=Asia/Shanghai必须加上,否则报错。

二 .配置不同的端口号：

修改bin目录下startup.sh文件，需要修改两个地方：

  1. 新增参数o,表示端口号
    在这里插入图片描述
    2.启动时加上端口号
    在这里插入图片描述
    保存，退出。

三、修改cluster.conf

在这里插入图片描述
注意：①这里的ip不能写成127.0.0.1，否则识别不了。②这里的ip是虚拟机固定的ip，即使服务重启也不变（需要配置）

遇见的问题：
nacos版本2.2.1，启动一个服务的三个不同端口，结果发现第一个启动正常，启动第二个报错如下：

网上查了，让建三个不同的文件夹：

在这里插入图片描述
建了之后，三个端口都能启动，但是执行：ps -ef|grep nacos | grep -v grep |wc -l 的值为1，就是虽然不报错，但是其实只有最新的那个端口启动成功。无奈之下，将版本换成1.4.2，也将nacos放在三个不同的文件夹下，分别启动，又报如下错误：

在这里插入图片描述
报错内容显示内存不足，查看startup.sh,配置如下：

默认启动2g的内存空间，修改下内存分配：
在这里插入图片描述
重启。执行ps -ef|grep nacos | grep -v grep |wc -l 值为3，成功！！！
