# centos常用环境安装

## 安装nodejs

参考：<https://segmentfault.com/a/1190000007124759> nodejs 官网：<https://nodejs.org/en/download/package-manager/#enterprise-linux-and-fedora> `curl --silent --location https://rpm.nodesource.com/setup_8.x | bash -` `yum -y install nodejs`

**安装cnpm，淘宝npm工具，提高npm下载包的速度**

cnpm：<https://npm.taobao.org/>

`npm install -g cnpm --registry=https://registry.npm.taobao.org`

## 安装docker (docker-ce)

官方文档：<https://docs.docker.com/install/linux/docker-ce/centos/> 参考：<http://www.runoob.com/docker/centos-docker-install.html>

step1:Docker 要求 CentOS 系统的内核版本高于 3.10 `uname -r`

step2:移除旧版本

```bash
yum remove docker \
           docker-client \
           docker-client-latest \
           docker-common \
           docker-latest \
           docker-latest-logrotate \
           docker-logrotate \
           docker-selinux \
           docker-engine-selinux \
           docker-engine
```

step3: 安装一些必要的系统工具

```bash
yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2
```

step4: 添加软件源信息，这里使用aliyun的。 官方源：<https://download.docker.com/linux/centos/docker-ce.repo> `yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo` step5:更新 yum 缓存 `yum makecache fast` step6:安装 Docker-ce `yum -y install docker-ce` step7:启动 Docker 后台服务 `systemctl start docker` step8:测试运行 hello-world `docker run hello-world`

**安装 docker-compose**

官方文档：<https://docs.docker.com/compose/install/> step1: 注意这里的版本号，最新版请从这里获取[Compose repository release page on GitHub](https://github.com/docker/compose/releases) `curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose` step2:添加可执行权限 `chmod +x /usr/local/bin/docker-compose` `docker-compose --version`

step3: \[可选] 安装 命令行提示 [Command-line completion](https://docs.docker.com/compose/completion/)

**使用国内docker仓库源**

针对Docker客户端版本大于 1.10.0 的用户 您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器(没有这个文件可以创建) 从这个地址获取aliyun专属源地址:<https://cr.console.aliyun.com/cn-hangzhou/mirrors>

```bash
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": ["https://****.mirror.aliyuncs.com","https://registry.docker-cn.com","https://hub-mirror.c.163.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
```

## 安装nginx

参考：<https://www.jianshu.com/p/1cad13e57c43>

step1:添加CentOS 7 EPEL 仓库 `yum install epel-release` step2:安装Nginx `yum install nginx`
