yum groupinstall "Development Tools"

yum install -y net-tools libaio numactl
yum -y install gcc gcc-c++ autoconf make
yum install openssl-devel bzip2-devel
sudo yum install libffi-devel

sudo yum install sqlite-devel
yum install xz-devel


查看是否安装某个依赖包
yum list installed libffi-devel

sshfs Centos

 
sudo yum install -y epel-release 
sudo yum install sshfs fuse
sshfs  -p 22  username@hostname:/remote/directory /local/directory -o reconnect -o allow_other

卸载 
fusermount -u /local/directory

其他参数:
-o allow_other：允许其他用户访问挂载的文件系统。
-o reconnect：如果连接中断，尝试重新连接。
-o ssh_command：指定用于连接远程文件系统的SSH命令。
-o idmap=user：映射远程文件系统的用户ID到本地用户ID。

本质是使用了sshd服务，可能需要重启一下sshd 
systemctl restart sshd

centos7添加阿里yum源

 
mv CentOS-Base.repo CentOS-Base.repo.bak

curl -O http://mirrors.aliyun.com/repo/Centos-7.repo -o /etc/yum.repos.d/CentOS-Base.repo  
curl -O http://mirrors.aliyun.com/repo/epel-7.repo -o /etc/yum.repos.d/epel.repo
yum clean all
yum makecache

sudo yum install epel-release
sudo yum install centos-release-scl
