首先进入到 wrapper/bin/目录下面，执行./SocAgentService-LINUX console 命令
[root@localhost ~]# cd socAgent/wrapper/bin/
[root@localhost bin]# ./SocAgentService-LINUX console出现如下提示：

0X03 解决办法
输入命令 which java 查找系统自带的 java 路径
当有软链时需要找到真正的 java 路径，如下所示真正的 java 路径是
/usr/java/jdk1.8.0_45/jre/bin/java
[root@localhost bin]# which java
/usr/bin/java
[root@localhost bin]# ll /usr/bin/java
lrwxrwxrwx. 1 root root 22 12月 18 11:01 /usr/bin/java -> /etc/alternatives/java
[root@localhost bin]# ll /etc/alternatives/java
lrwxrwxrwx. 1 root root 73 12月 18 11:01 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre/bin/java- 修改 socAgent/wrapper/conf/agentServiceWrapper.conf 文件，把 JAVA_HOME 修改成 java
路径中对应的 jre 目录，如上的路径需要修改成
set.SOC_JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre- 修改 socAgent/wrapper/conf/protectServiceWrapper.conf 文件，把 JAVA_HOME 修改成 java
路径中对应的 jre 目录，如上图中的路径需要修改成
set.SOC_JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre
更改完成后再重新进行安装
[root@localhost bin]# ./install.sh
