一、更新yum源
# 对于 CentOS 7
sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \\
-e 's|^#baseurl=http://mirror.centos.org|baseurl=https://mirrors.tuna.tsinghua.edu.cn|g' \\
-i.bak \\
/etc/yum.repos.d/CentOS-*.repo
# 对于 CentOS 8
sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \\
-e 's|^#baseurl=http://mirror.centos.org/$contentdir|baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos|g' \\
-i.bak \\
/etc/yum.repos.d/CentOS-*.repo
然后执行
yum makecache
二、安装必要软件
先以下这些，如有遗漏再添加
yum install screen gcc g++ cmake make git
yum install epel-release
json命令行工具
yum install jq
三、系统设置
设置hostname
hostnamectl set-hostname master
关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
将 SELinux 设置为 permissive 模式（相当于将其禁用）
sudo setenforce 0
sudo sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config
关闭swap
swapoff -a
sed -ri 's/.*swap.*/#&/' /etc/fstab
允许 iptables 检查桥接流量
cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
br_netfilter
EOF
cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sudo sysctl --system
设置AllowTcpForwarding，不过默认也是yes
vim /etc/ssh/sshd_config
AllowTcpForwarding yes
三、开发环境搭建
3.1 docker
sudo curl -sSL https://get.daocloud.io/docker | sh
systemctl start docker
systemctl enable docker # 开机自启
设置镜像源
vim /etc/docker/daemon.json
"registry-mirrors": ["http://hub-mirror.c.163.com"]
sudo systemctl daemon-reload
sudo systemctl restart docker
3.2 k8s系列
基础设置
cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
http://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
exclude=kubelet kubeadm kubectl
EOF
全部命令， 看着办 ，–disableexcludes=kubernetes 这个参数别忘了
sudo yum install -y kubelet-1.20.9 kubeadm-1.20.9 kubectl-1.20.9 --disableexcludes=kubernetes
sudo systemctl enable --now kubelet
3.2.1 kubectl
sudo yum install -y kubectl-1.23.12 --disableexcludes=kubernetes
3.2.2 rke
cd /opt/software
wget https://github.com/rancher/rke/releases/download/v1.4.0/rke_linux-amd64
cp /opt/software/rke_linux-amd64 rke
cp /opt/software/rke /usr/bin/
chmod a+x /usr/bin/rke
3.3 软件存放目录
mkdir /opt/software/
mkdir /opt/module/
3.4 go
mkdir /opt/module/go/
mkdir -p /opt/module/gopath/go1.17 #gopath放在用户目录下，避免互相影响
cd /opt/module/gopath/go1.17
mkdir bin
mkdir pkg
mkdir src
cd /opt/software/
wget https://go.dev/dl/go1.17.13.linux-amd64.tar.gz
tar -zxvf go1.17.13.linux-amd64.tar.gz -C /opt/module/go/
cd /opt/module/go/
mv ./go ./go1.17
vim /etc/profile.d/my_env.sh
export GOROOT=/opt/module/go/go1.17 ##Golang安装目录
export PATH=$GOROOT/bin:$PATH
export GOPATH=/opt/module/gopath/go1.17 ##Golang项目目录
source /etc/profile
3.5 java
https://www.oracle.com/java/technologies/downloads/#java8
上传到/opt/software/
tar -zxvf jdk-8u351-linux-x64.tar.gz -C /opt/module/
vim /etc/profile.d/my_env.sh
#JAVA_HOME
export JAVA_HOME=/opt/module/jdk1.8.0_351
export PATH=$PATH:$JAVA_HOME/bin
source /etc/profile
3.6 x11 图形界面
yum install xorg-x11-xauth.x86_64 xorg-x11-server-utils.x86_64 dbus-x11.x86_64 xclock -y
vim /etc/ssh/sshd_config
X11Forwarding yes
X11UseLocalhost no # 禁止将X11请求绑定到本地回环地址上
vim ~/.bashrc
本机ip，不是centos服务器的ip
export DISPLAY=192.168.137.1:0.0
使用图像界面的时候最好使用mobaxterm，不用其他额外配置，用xshell目前还没有配置成功过
3.7 goland
cd /opt/software
wget "https://download-cdn.jetbrains.com/go/goland-2021.3.3.tar.gz?_ga=2.228962204.1446260195.1668308974-1416473211.1640081858&_gac=1.228096495.1668308993.Cj0KCQiApb2bBhDYARIsAChHC9u5W7kFfSWKTZ6fcjpIp71x-i1BYTxJ04d-CsexDx1lu7j8vPoBhWoaAh24EALw_wcB&_gl=1*q5lwqy*_ga*MTQxNjQ3MzIxMS4xNjQwMDgxODU4*_ga_9J976DJZ68*MTY2ODMwODk3My4yLjEuMTY2ODMwOTA0MS4wLjAuMA.." -O /opt/software/goland-2021.3.3.tar.gz
tar -zxvf goland-2021.3.3.tar.gz -C /opt/module/
运行goland的时候，建议使用安装java，目前没找到自己安装的java为啥启动不了，好像是jre不行？
yum install java
3.8 git 升级到2.x
yum remove git*
sudo yum install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm
yum install git
