一、下载nacos
https://github.91chi.fun/https://github.com//alibaba/nacos/releases/download/2.1.0/nacos-server-2.1.0.tar.gz
二、上传并解压nacos
tar -xzvf nacos-server-2.1.0.tar.gz
三、启动nacos
cd /nacos/bin sh startup.sh -m standalone
如果输入如下信息，恭喜你成功了。

我安装的是openjdk，报错
ERROR: Please set the JAVA_HOME variable in your environment, We need java(x64)! jdk8 or later is better! !!
1、配置JAVA_HOME
#查找java按照路径 which java ls -lrt /usr/bin/java ls -lrt /etc/alternatives/java #编辑配置文件 vim /etc/profile export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.322.b06-1.el7_9.x86_64/jre/bin/java #刷新配置文件 source /etc/profile
继续执行sh startup.sh -m standalone
2、安装javac
yum install java-1.8.0-openjdk-devel.x86_64
3、再次启动单机模式 
四、访问验证
