If you use yum to install software in CentOS6.5 installed by yourself, the Error 404 is always prompted. Baidu then finds that you have to set the yum source. After CentOS is installed, you generally need to modify the yum source to achieve an ideal speed when installing and updating the rpm package. There are 163 sources and sohu sources that are relatively fast in China. Here we use the 163 source as an example. 1. cd/etc/yum. repos. d2. mv CentOS-Base.repo CentOS-Base.repo.backup3. wget http://mirrors.163.com/.help/CentOS6-Base-163.repo4. mv CentOS6-Base-163.repo CentOS-Base.repo5. yum clean all
