yum -y remove javapackages-tools.noarch
- 执行
vi /etc/profile，在/etc/profile文件最后中添加环境变量，添加内容如下

- 执行
source /etc/profile使环境变量生效
安装Nacos
- 前往 https://github.com/alibaba/nacos/releases 下载需要安装的版本，我使用的是
nacos-server-2.1.1.tar.gz - 将安装包上传到主机任意目录，我放到了
/home目录下 - 执行
tar -xzvf /home/nacos-server-2.1.1.tar.gz -C /usr/local解压到指定目录 Nacos的配置文件和数据库脚本在/usr/local/nacos/conf目录下，有需要的可以修改后再启动- 执行
sh /usr/local/nacos/bin/startup.sh -m standalone启动Nacos，启动成功如下
[root@0001 ~]# sh /usr/local/nacos/bin/startup.sh -m standalone
/usr/lib/jvm/jre/bin/java -Djava.ext.dirs=/usr/lib/jvm/jre/jre/lib/ext:/usr/lib/jvm/jre/lib/ext -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xloggc:/usr/local/nacos/logs/nacos_gc.log -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=100M -Dloader.path=/usr/local/nacos/plugins/health,/usr/local/nacos/plugins/cmdb,/usr/local/nacos/plugins/selector -Dnacos.home=/usr/local/nacos -jar /usr/local/nacos/target/nacos-server.jar --spring.config.additional-location=file:/usr/local/nacos/conf/ --logging.config=/usr/local/nacos/conf/nacos-logback.xml --server.max-http-header-size=524288
nacos is starting with standalone
nacos is starting，you can check the /usr/local/nacos/logs/start.out
- 启动成功后，访问
ip:8848/nacos，默认用户名nacos，密码nacos - 停止
Nacos的命令sh /usr/local/nacos/bin/shutdown.sh Nacos的日志文件路径/usr/local/nacos/logs，如果启动失败可以查看日志
