replace domestic sources
What is domestic source, in layman's terms, is the application market, the Android system has the Android application market, the Apple system has the Apple application market, and the Linux system also has the Linux application market
CentOS version: yum source
Ubuntu version: apt-get source
Note 1 : If you just simply configure Linux and install JDK , Tomcat and other tools, you don't need to update the domestic source, which is mainly to solve the slow speed of accessing foreign servers.
Note 2 : yum is just the command, epel is the source.
CentOS is replaced by Alibaba Cloud's source
1. Make sure to install wget before the replacement. If you don’t have wget installed, you can install it directly
yum list wget
yum -y install wget2. Backup first
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak 3. Download the yum source of Alibaba Cloud to /etc/yum.repos.d/
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 4. Clear cache
yum clean all 5. Update the local YUM cache
yum makecache 6. Install a software and try it out to see if the download source has changed to Alibaba Cloud
yum -y install lrzsz 
Note: lrzsz is a program that can replace FTP upload and download in Linux.
You want to download sz [find the file you want to download];
If you want to upload, rz browse to find the file you want to upload locally.
It should be noted that this command cannot be used in the putty interface!
