# 部署OpenHPC

## 1. 安装OpenHPC

* 可下载的tar文件：一个包含二进制包的仓库以及任何可用的更新，另一个包含RPMS的源代码仓库。tar文件还包含一个小的bash脚本，用来配置yum在下载后使用本地的资源库。使用时，只需解压你想存放本地仓库的tarball，然后执行 `make_repo.sh`脚本。

```bash
ls /opt/ohpc/repos
# 输出：
# CentOS_7  make_repo.sh  OpenHPC-1.3.9.CentOS_7.x86_64.tar OpenHPC.local.repo README
```

```bash
# ./make_repo.sh
--> Creating OpenHPC.local.repo file in /etc/yum.repos.d
--> Local repodata stored in /opt/ohpc/repos
```

```bash
cat /etc/yum.repos.d/OpenHPC.local.repo 
# [OpenHPC-local]
# name=OpenHPC-1.3 - Base
# baseurl=file:///opt/ohpc/repos/CentOS_7
# gpgcheck=1
# gpgkey=file:///opt/ohpc/repos/CentOS_7/repodata/repomd.xml.key


# [OpenHPC-local-updates]
# name=OpenHPC-1.3.9 - Updates
# baseurl=file:///opt/ohpc/repos/CentOS_7/updates
# gpgcheck=1
# gpgkey=file:///opt/ohpc/repos/CentOS_7/updates/repodata/repomd.xml.key
```

## 2. 使用方法

```bash
yum list | grep OpenHPC  #查看所有ophc的源，可以选择安装
yum install gnu8-compilers-ohpc.x86_64  #安装示例
```

## 3. 安装OpenHPC软件包

* CentOS7使用OpenHPC安装高版本gcc, g++, gfortran等工具

```bash
yum -y install gnu8-compilers-ohpc.x86_64
```

* 环境变量为：

```bash
export GNU_HOME=/opt/ohpc/pub/compiler/gcc/8.3.0 && \
export PATH=$GNU_HOME/bin:$PATH && \
export LD_LIBRARY_PATH=$GNU_HOME/lib:$GNU_HOME/lib64:$LD_LIBRARY_PATH && \
export INCLUDE=$GNU_HOME/include:$INCLUDE && \
export MANPATH=$GNU_HOME/share/man:$MANPATH
```

```bash
gcc -v
```

## 4. 可能需要安装的软件包

**注**：根据个人情况安装，不一定需要安装

```bash

```

## 5. 安装module

```bash
# 目前发现，部署openhpc的autotools（或其他包ohpc, EasyBuild），会自动部署好module。因此不需要单独安装。
# 实在不行再安装 environment-modules。
```
