重启网卡

  • 不能使用servicesystemctl
  • 方法:nmcli c reload +网卡名
$ nmcli c reload ens192
$ nmcli c down ens192
$ nmcli c up ens192

立即生效connection,有3种方法

$ nmcli c up ethX
$ nmcli d reapply ethX
$ nmcli d connect ethX

查询网卡

$ nmcli

路由转发

$ modprobe br_netfilter
$ vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-iptables=1
net.bridge.bridge-nf-call-ip6tables = 1
$ sysctl -p

防火墙

systemctl stop firewalld
systemctl disable firewalld
systemctl status firewalld

selinux

setenforce 0 && getenforce
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

修改最大文件句柄数和最大进程数

$ vim /etc/security/limits.conf
......
* soft nofile 102400
* hard nofile 102400
$ sysctl -p 
$ ulimit -n

设置 swappiness

设置swappiness,控制运行时内存的相对权重,过多的交换空间会引起GC耗时的激增.

临时设置指令:

sysctl -w vm.swappiness=10
#临时设置查看指令
cat /proc/sys/vm/swappiness

永久设置指令:

echo vm.swappiness = 10 >> /etc/sysctl.conf

关闭透明大页面transparent_hugepage

临时关闭指令1:

echo never > /sys/kernel/mm/transparent_hugepage/enabled

临时关闭指令2:

echo never > /sys/kernel/mm/transparent_hugepage/defrag

永久关闭,配置信息落盘到配置文件,机器重新有效。

$ vim /etc/rc.d/rc.local
.......
if test -f /sys/kernel/mm/transparent_hugepage/enabled;
then echo never > /sys/kernel/mm/transparent_hugepage/enabled

if test -f /sys/kernel/mm/transparent_hugepage/defrag;

yum 与 dnf

RHEL 8 / CentOS 8上的软件包管理工具 DNF(Dandified YUM)已设置为默认值。

但是,[yum]命令也作为指向[dnf]的链接而存在,因此可以以相同的用法使用[yum]或[dnf]。


实际上,RedHat上的官方文档使用RHEL 8的[yum]命令给出了示例

dnf 更新软件库

在CentOS服务器成为生产系统之后,可能很难更新系统,但是至少在安装后,将CentOS服务器更新为最新版本。

$ dnf -y upgrade
CentOS-8 - AppStream                                                                     92  B/s |  38  B     00:00
Error: Failed to download metadata for repo 'AppStream': Cannot prepare internal mirrorlist: No URLs in mirrorlist

如果您仍然在管理运行CentOS 8的系统,并且尝试使用dnf update或yum update更新包,您将遇到以下错误:Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist

现在CentOS已经转移到Stream(一种滚动发布的Linux发行版,介于Fedora的上游开发和RHEL的下游开发之间),许多用户正在转向CentOS的替代方案。其他人则决定通过迁移到CentOS Stream 8来坚持使用CentOS。


CentOS Linux 8早死了,它在2021年12月31日达到了生命的终结(EOL),因此它不再从官方CentOS项目获得开发资源。


这意味着在2021年12月31日之后,要更新您的CentOS安装,您需要将镜像更改为CentOS Vault Mirror,在那里它们将被永久存档。

从CentOS 8迁移到CentOS Stream 8,执行以下命令:

sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

或者,您也可以通过运行以下命令指向基于cloudflare的仓库存储库:

sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-Linux-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.epel.cloud|g' /etc/yum.repos.d/CentOS-Linux-*

继续更新软件
