主要适用于单机版nacos开机自启配置，具体步骤如下。

1.编写Systemd 服务

Systemd 服务的内容主要分为三个部分，控制单元（unit）的定义、服务（service）的定义、以及安装部分。

vim /lib/systemd/system/nacos.service

直接粘贴以下内容，Description为描述，After=network.target表示在网口启动后启动

[Unit]
Description=nacos
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/nacos/bin/startup.sh -m standalone
ExecReload=/usr/local/nacos/bin/shutdown.sh
ExecStop=/usr/local/nacos/bin/shutdown.sh
PrivateTmp=true

[Install]
WantedBy=multi-user.target

2.修改nacos启动文件

其中的jdk路径以自己实际安装路径为准

vim /usr/local/nacos/bin/startup.sh

#!/bin/bash

cygwin=false
darwin=false
os400=false
case "`uname`" in
CYGWIN*) cygwin=true;;
Darwin*) darwin=true;;
OS400*) os400=true;;
esac
error_exit ()
{
    echo "ERROR: $1 !!"
    exit 1
}
[ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=/usr/local/jdk-18.0.2.1
#[ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=$HOME/jdk/java
#[ ! -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
"startup.sh" 149L, 5229C

 3.设置nacos开机启动

systemctl daemon-reload              #重新加载服务配置
systemctl enable nacos.service       #设置为开机启动
systemctl start nacos.service        #启动nacos服务
systemctl stop nacos.service         #停止nacos服务
systemctl stop firewalld.service     #停止防火墙
systemctl disable firewalld.service  #禁止防火墙开机启动

4.启动效果
