在docker容器中查看hph-fpm运行情况，使用命令：netstat -lntup|grep 9000，提示找不到命令netstat，然而docker容器（ubuntu环境）apt-get命令安装(install)netstat失败

在什么情况下？

docker容器、Ubuntu系统

在docker容器中查看hph-fpm运行情况，使用命令：netstat -lntup|grep 9000，提示找不到命令netstat，然而docker容器（ubuntu环境）apt-get命令安装(install)net-tools失败

查看php-fpm没有运行，端口：9000

查看命令

netstat -lntup|grep 9000

提示

bash: netstat: command not found

解决方法就是使用命令apt-get install net-tools安装解决了

如果出现安装错误，查看了很多资料，都是建议建议先做

apt-get update

然、继续后续
