## 安装指南

Ubuntu18.04

centos7.9

设置允许以root身份远程ssh登录：```vim /etc/ssh/sshd-config```

### 0. 使用方法

**step1:** 确保安装了git，给集群内所有服务器配置好go语言环境、rocksDB编译环境 （以Centos系统为例）

1. Go语言安装配置

   ``````shell
   # 下载源码
   wget https://storage.googleapis.com/golang/go1.16.3.linux-amd64.tar.gz
   # 解压缩
   tar -xf go1.16.3.linux-amd64.tar.gz
   # 配置环境变量
   vim ~/.bashrc
   	export GOROOT="golang解压缩位置"
   	export GOPATH="选择GOPATH目录"
   	export PATH=$GOPATH/BIN:$GOROOT/bin:$PATH
   	export GOPROXY=https://goproxy.io,direct
   source ~/.bashrc
   
   vim /etc/profile
   	export GOROOT="golang解压缩位置"
   	export GOPATH="选择GOPATH目录"
   	export PATH=$GOPATH/BIN:$GOROOT/bin:$PATH
   	export GOPROXY=https://goproxy.io,direct
   source /etc/profile
   ``````

2. 源码编译环境

   ``````shell
   yum -y update
   yum -y install gcc
   yum -y install glibc-static.x86_64
   yum -y install gflags-devel
   yum -y install snappy-devel
   yum -y install zlib-devel
   yum -y install bzip2-devel  
   yum -y install libstdc++-devel
   yum -y install lz4-devel
   yum -y install libzstd-devel
   
   # 安装jemalloc
   # wget https://github.com/jemalloc/jemalloc/releases/download/5.0.1/jemalloc-5.0.1.tar.bz2
   # wget https://gitee.com/wanttobeamaster/jemalloc/repository/archive/5.0.1?format=tar.gz -O jemalloc-5.0.1.tar.gz
   yum -y install bzip2
   tar -jxvf jemalloc-5.0.1.tar.bz2 
   cd jemalloc-5.0.1
   yum -y install autogen autoconf
    
   ./autogen.sh
   make -j2
   make install
   ldconfig
   cd ../
   rm -rf jemalloc-5.0.1 jemalloc-5.0.1.tar.bz2
   
   rm -rf ~/.cache/go-build
   
   
   
   ``````



**step2 :** 在中控机上，下载ela-up源码 ：```go get gitee.com/wanttobeamaster/ela-up``` 或 ```git clone https://gitee.com/wanttobeamaster/```

**step3 :** 编辑 ```/home/hosts``` 文件，写入集群内主机的 ```ip ssh-passed```，可执行脚本会按行读取内容

**step4 : ** 在中控机器上下载expect工具```yum install expect``` 

**step5 :** 在ela-up目录下运行```./node-man.sh```根据提示输入[yes / no]；完成后，所有机器会自动下载并编译源码

**step6:** 启动集群



### 1. download.sh

```download.sh``` 用于本地环境下连接网络（校园网情况下）、下载源代码、编译源代码

### 2. exp.sh

```exp.sh``` 通过expect工具，实现远程ssh登录，达到在远程环境下执行目标指令的目的，此处借助expect工具，实现远程执行```download.sh```脚本的作用

### 3. node-man.sh

```node-man.sh``` 节点管理脚本，集成了exp.sh。node-man.sh会以行为单位，读取```/home/hosts```文件，hosts文件内容为目标主机的ip和ssh密码。默认的登入角色为root。

hosts格式如下：

``````shell
121.248.55.193 passwd
121.248.49.238 passwd
121.248.2.124 passwd
``````
