codis环境搭建

1.docker环境准备

1.2 docker 准备

1.2.1 无对外暴露端口

# centos环境
$ docker run -dit --name codis centos
# 查看镜像
$ docker ps -a 
# 进入容器
$ docker attach ${容器id}

1.2.2 对外暴露端口

# 对外暴露8080端口
$ docker run -dit -p8080:8080 --name codis2 centos
94a1fd93a54481414c745122f493eaccb6c845fc7114cf97aeb9f3dd995687f4
# 查看暴露的端口
$ docker ps -a
CONTAINER ID   IMAGE          COMMAND                  CREATED          STATUS                     PORTS                                                  NAMES
94a1fd93a544   centos         "/bin/bash"              11 seconds ago   Up 9 seconds               0.0.0.0:8080->8080/tcp, :::8080->8080/tcp              codis2

1.2 centos环境软件包

# 更新yum
$ yum update  -y

# 安装包
$ yum install -y vim wget tree lrzsz git make gcc

2.安装Go环境

考虑到codis是3.0版本，基于go的1.8版本开发的

2.1 下载安装

# 下载 Go 安装包
$ wget https://studygolang.com/dl/golang/go1.8.7.linux-amd64.tar.gz
# 解压
$ tar -zxf go1.8.7.linux-amd64.tar.gz /usr/local/

# 查看安装路径
$ pwd
/usr/local/go

2.2 环境配置

vim ~/.bashrc

export GOROOT=/usr/local/go
export GOPATH=/home/apps/devgo
export GOBIN=/home/apps/devgo/bin
export PATH=$PATH:$GOROOT/bin

2.3 Go环境检查

# 版本
[root@f67a5365a626 go]# go version
go version go1.8.7 linux/amd64

3.安装godep

3.1 安装

$ go get -u github.com/tools/godep

3.2 检查

[root@f67a5365a626 devgo]# which godep
which: no godep in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin)
# 如果输入which godep 报命令command not found的错误,可以这样解决
[root@f67a5365a626 devgo]# cp $GOPATH/bin/godep  /usr/local/bin/
[root@f67a5365a626 devgo]# which godep
/usr/local/bin/godep

4.安装codis

4.1 下载

$ mkdir -p $GOPATH/src/github.com/CodisLabs

# 下载codis 源代码
$ cd $GOPATH/src/github.com/CodisLabs && git clone https://github.com/CodisLabs/codis.git -b release3.0

4.2 安装

$ cd $GOPATH/src/github.com/CodisLabs/codis

$ 

.....

# 接下来，我们需要处理一下 bin/ 下的命令工具
$ cp codis-* /usr/local/bin
$ cp redis-* /usr/local/bin

5.安装etcd

# 下载 etcd
$ wget  https://github.com/coreos/etcd/releases/download/v2.3.7/etcd-v2.3.7-linux-amd64.tar.gz

# 解压
$ tar -zxf etcd-v2.3.7-linux-amd64.tar.gz

# etcd路径文件
$ cd etcd-v2.3.7-linux-amd64 && cp etcd /usr/local/bin/ &&  cp etcdctl /usr/local/bin/

# 验证是否正常
[root@f67a5365a626 local]# etcd --version
etcd Version: 2.3.7
Git SHA: fd17c91
Go Version: go1.6.2
Go OS/Arch: linux/amd64
