• 上传并解压JKD

[root] tar -zvxf jdk-8u301-linux-x64.tar.gz -C /home 

• 上传并解压nacos

[root] mkdir /home/nacos
[root] tar -zvxf nacos-server-2.0.2.tar.gz -C /home/nacos

• 修改配置文件，开启mysql支持

[root] vim /home/nacos/conf/application.properties

db.user=root
db.password=root

• 启动nacos

[root] sh /home/nacos/bin/startup.sh -m standalone 

# 查询启动状态
[root] ps -ef|grep nacos

# 查看启动端口
[root] netstat -ntlp

• 修改nocas启动脚本，修改JDK路径，注释下面3个，配置单实例模式 export MODE=“standalone”

[root] vim /home/nacos/bin/startup.sh

[ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=/home/jdk1.8.0_301
# [ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=/usr/java
# [ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=/opt/taobao/java
# [ ! -e "$JAVA_HOME/bin/java" ] && unset JAVA_HOME

if [ -z "$JAVA_HOME" ]; then
  if $darwin; then

    if [ -x '/usr/libexec/java_home' ] ; then
      export JAVA_HOME=`/usr/libexec/java_home`

    elif [ -d "/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home" ]; then
      export JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home"
    fi
  else
    JAVA_PATH=`dirname $(readlink -f $(which javac))`
    if [ "x$JAVA_PATH" != "x" ]; then
      export JAVA_HOME=`dirname $JAVA_PATH 2>/dev/null`
    fi
  fi
  if [ -z "$JAVA_HOME" ]; then
        error_exit "Please set the JAVA_HOME variable in your environment, We need java(x64)! jdk8 or later is better!"
  fi
fi

export SERVER="nacos-server"
export MODE="standalone"

• 配置自动启动脚本

 vim /etc/systemd/system/website.service 
[Unit]
Description=nacos
After=network.target

[Service]
Type=forking
Environment="JAVA_HOME=/opt/jdk/1.8/jdk1.8.0_351"
ExecStart=/opt/nacos/nacos/bin/startup.sh -m standalone
ExecReload=/opt/nacos/nacos/bin/shutdown.sh
ExecStop=/opt/nacos/nacos/bin/shutdown.sh
PrivateTmp=true

[Install]
WantedBy=multi-user.target

• 自启配置：

[root] systemctl daemon-reload
[root] systemctl enable nacos.service
[root] systemctl restart nacos.service

• 访问nacos

地址：http://IP:8848/nacos 账号：nacos 密码：nacos
