CentOS7 笔记 博客分类: linux
永久改变Console背景色:
vi /etc/profile
#rick begin, set console color setterm -foreground black -background white -store #rick end
安装java8:
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u141-b15/336fa29ff2bb4ef291e347e091f7f4a7/jdk-8u141-linux-x64.rpm" rpm -ivh jdk-8u141-linux-x64.rpm
永久关闭峰鸣声:
vi /etc/profile
#disable beep rmmod pcspkr
支持挂载NTFS,并自动发现win7系统引导:
cd /etc/yum.repos.d wget http://mirrors.aliyun.com/repo/epel-7.repo yum update yum install ntfs-3g grub2-mkconfig -o /boot/grub2/grub.cfg
默认不启动Gnome(手动启动startx, 手动关闭init 5). 最小化安装时不需要:
systemctl set-default multi-user.target
安装ftp服务:其实没必要装这个, 用sftp就行了.
yum install vsftpd systemctl enable vsftpd
关闭防火墙:
systemctl stop firewalld.service systemctl disable firewalld.service
安装git, telnet:
yum install git yum install telnet
安装go语言 (不用yum安装, 那个go版本太老了):
wget https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz tar zxvf go1.8.3.linux-amd64.tar.gz mv go /usr/local/
vi /etc/profile:
export PATH=$PATH:/usr/local/go/bin export GOROOT=/usr/local/go
测试:
source /etc/profile go version
安装docker:
yum install docker systemctl enable docker.service systemctl start docker.service
解决docker不能访问gcr.io的问题, *
vi /etc/sysconconfig/docker
HTTP_PROXY=192.168.85.43:7070 #这是我的代理, 需要改成你自己的. http_proxy=192.168.85.43:7070 HTTPS_PROXY=192.168.85.43:7070 https_proxy=192.168.85.43:7070 export HTTP_PROXY HTTPS_PROXY http_proxy https_proxy
重启docker
service docker restart
测试一下, 若没有问题则*成功
docker pull gcr.io/google_containers/kube-cross:v1.8.3-1
安装etcd 服务器:
git clone https://github.com/coreos/etcd.git cd etcd ./build cd .. mv etcd /usr/local
vi /etc/profile
export PATH=$PATH:/usr/local/etcd/bin
测试
source /etc/profile etcd
设置etcd自启动:
vi /usr/lib/systemd/system/etcd.service
[Unit] Description=etcd server After=network.target [Service] Type=simple WorkingDirectory=/usr/local/etcd EnvironmentFile=/usr/local/etcd/etcd.conf ExecStart=/usr/local/etcd/bin/etcd [Install] WantedBy=multi-user.target
测试服务:
systemctl enable etcd.service systemctl start etcd.service etcdctl cluster-health
单机环境安装kubernetes(注意是单机环境, 所有的组件都在一个台物理机上):
wget https://github.com/kubernetes/kubernetes/releases/download/v1.7.1/kubernetes.tar.gz tar zxvf kubernetes.tar.gz cd kubernetes ./cluster/get-kube-binaries.sh cd client tar zxvf kubernetes-client-linux-amd64.tar.gz cd ../server tar xzvf kubernetes-server-linux-amd64.tar.gz cd ../../ mv kubernetes /usr/local
vi /etc/profile
#install kubernetes client export PATH=$PATH:/usr/local/kubernetes/client/kubernetes/client/bin #install kubernetes server export PATH=$PATH:/usr/local/kubernetes/server/kubernetes/server/bin
测试
source /etc/profile kubectl kubeadm
设置kubernate api server开机启动:
vi /usr/lib/systemd/system/kube-apiserver.service
[Unit] Description=Kubernetes API Server After=etcd.service Wants=etcd.service [Service] ExecStart=/usr/local/kubernetes/server/kubernetes/server/bin/kube-apiserver --insecure-bind-address=0.0.0.0 --insecure-port=8080 --etcd_servers=http://127.0.0.1:2379 --service-cluster-ip-range=172.0.0.0/16 --logtostderr=false --log-dir=/log/kubernetes --v=3 Restart=on-failure Type=notify LimitNOFILE=65536 [Install] WantedBy=multi-user.target
systemctl enable kube-apiserver.service systemctl start kube-apiserver.service
设置kubernate controller manager 开机启动:
vi /usr/lib/systemd/system/kube-controller-manager.service
[Unit] Description=Kubernetes Controller Manager After=kube-apiserver.service Requires=kube-apiserver.service [Service] ExecStart=/usr/local/kubernetes/server/kubernetes/server/bin/kube-controller-manager --master=http://127.0.0.1:8080 --logtostderr=false --log-dir=/log/kubernetes --v=3 Restart=on-failure LimitNOFILE=65536 [Install] WantedBy=multi-user.target
systemctl enable kube-controller-manager systemctl start kube-controller-manager
设置kubernate scheduler server开机启动:
vi /usr/lib/systemd/system/kube-scheduler.service
[Unit] Description=Kubernetes Scheduler Service After=kube-apiserver.service Requires=kube-apiserver.service [Service] ExecStart=/usr/local/kubernetes/server/kubernetes/server/bin/kube-scheduler --master=http://127.0.0.1:8080 --logtostderr=false --log-dir=/log/kubernetes --v=3 Restart=on-failure LimitNOFILE=65536 [Install] WantedBy=multi-user.target
systemctl enable kube-scheduler systemctl start kube-scheduler
