CentOS环境下搭建Nacos（二进制、非mysql）-526互联

　　Nacos中文官网：https://nacos.io/zh-cn/。

　　我这里部署的Nacos版本是2.0.4，目前官网推荐版本为2.1.1。

(1).环境准备

　　在Nacos2.X部署手册中，必备条件只有JDK需要1.8及其以上版本。

　　JDK的安装我就不做展示了，各位看官参考CentOS7下搭建Tomcat服务器中的(3).JDK的安装和配置。

(2).二进制安装Nacos

　　将下载好的压缩包上传至服务器，解压配置并启动

[root@youxi1 ~]$ tar zxvf nacos-server-2.0.4.tar.gz -C /usr/local/
[root@youxi1 ~]$ cd /usr/local/nacos/bin/

//如果出现JAVA_HOME为空
[root@youxi1 bin]$ echo $JAVA_HOME
 
//或执行单机模式启动报如下错误
[root@youxi1 bin]$ sh startup.sh -m standalone
which: no javac in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/usr/local/erlang/bin:/usr/local/rabbitmq/rabbitmq_server
-3.9.11/sbin:/home/admin/.local/bin:/home/admin/bin)

ERROR: Please set the JAVA_HOME variable in your environment, We need java(x64)! jdk8 or later is better! !!
//那么需要对启动脚本进行修改，在第33行添加如下内容
[root@youxi1 bin]$ vi startup.sh
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.352.b08-2.el7_9.x86_64/jre

//保存退出后，再次执行启动命令，-m standalone表示为单机模式
[root@youxi1 bin]$ sh startup.sh -m standalone

nacos is starting with standalone
