 问题1：

参考连接：https://blog.csdn.net/silence_fengxuan/article/details/105581366

现象：

 

 

 原因：

输入echo $JAVA_HOME结果为空，说明没有配置java环境变量

解决办法：

配置JAVA环境变量

1.找到jdk安装路径

[root@localhost bin]# ls -lrt /usr/bin/java
lrwxrwxrwx 1 root root 22 Mar 15 09:59 /usr/bin/java -> /etc/alternatives/java
[root@localhost bin]# ls -lrt /etc/alternatives/java
lrwxrwxrwx 1 root root 73 Mar 15 09:59 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64/jre/bin/java
[root@localhost bin]# cd /usr/lib/jvm
[root@localhost jvm]# ll
total 4
drwxr-xr-x 3 root root 4096 Mar 15 09:59 java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64
lrwxrwxrwx 1 root root   21 Mar 15 09:59 jre -> /etc/alternatives/jre
lrwxrwxrwx 1 root root   27 Mar 15 09:59 jre-1.8.0 -> /etc/alternatives/jre_1.8.0
lrwxrwxrwx 1 root root   35 Mar 15 09:59 jre-1.8.0-openjdk -> /etc/alternatives/jre_1.8.0_openjdk
lrwxrwxrwx 1 root root   51 Mar 15 09:59 jre-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64 -> java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64/jre
lrwxrwxrwx 1 root root   29 Mar 15 09:59 jre-openjdk -> /etc/alternatives/jre_openjdk

2. 在/etc/profile文件下添加以下代码并执行

export JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64/          
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
 
[root@localhost ~]# source /etc/profile

3.重新执行nacos启动脚本
