Fedora/CentOS使用技巧

命令

获取系统安装包的编译源码及脚本

# dnf download --source package
# yumdownloader --source virt-viewer

远程连接windows

# yum install freerdp
### 自动挂载home目录
# xfreerdp /u:win /p:123456 /v:192.168.124.230 +home-drive

指定程序运行CPU

# yum install python-schedutils.x86_64
# taskset -c <cpu_id> <pid/command>

配置

SSH登入很慢

### 编辑/etc/ssh/sshd_config文件，找到如下属性，将UseDNS设置为no，然后注释GSSAPIAuthentication
###    UseDNS no
###    # GSSAPIAuthentication yes
# vim /etc/ssh/sshd_config
# systemctl restart sshd

设置阿里源

# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
# yum makecache

关闭SELINUX

# setenforce 0
# vim /etc/selinux/config
SELINUX=disabled
