龙芯3A3000搭建分布式存储服务etcd

http://ask.loongnix.org/?/article/93

etcd 是一个应用在分布式环境下的 key/value 存储服务。

由于Kubernetes要使用到etcd，所以第一步就是进行etcd的搭建。

etcd是一个Go语言编写的软件。

搭建环境

本文的实验都是在龙芯3A3000机器上。
操作系统是loongnix（Fedora21）20170512版本。
GO版本：go1.7.5 linux/mips64le

开始搭建

首先打开终端，配置GOPATH

# export GOPATH=/usr/lib/golang

进入GOPATH目录下

# cd $GOPATH

在$GOPATH的src目录下创建嵌套文件夹github.com/coreos

# mkdir -p $GOPATH/src/github.com/coreos

进入创建的文件夹下

# cd $GOPATH/src/github.com/coreos

下载etcd 2.3.6版本

# git clone  -b  v2.3.6 https://github.com/coreos/etcd.git

进入下载的etcd 文件夹下

# cd etcd

开始编译

# ./build

出现如下错误

github.com/coreos/etcd/Godeps/_workspace/src/github.com/boltdb/bolt
Godeps/_workspace/src/github.com/boltdb/bolt/db.go:98: undefined: maxMapSize
Godeps/_workspace/src/github.com/boltdb/bolt/db.go:98: invalid array bound maxMapSize

根据maxMapSize关键字找原因，使用grep "maxMapSize" ./* -r 找出路径

# grep "maxMapSize" ./* -r

搜索出如下内容

./Godeps/_workspace/src/github.com/boltdb/bolt/db.go:  data     *[maxMapSize]byte
./Godeps/_workspace/src/github.com/boltdb/bolt/db.go:   if size > maxMapSize {
./Godeps/_workspace/src/github.com/boltdb/bolt/db.go:   if sz > maxMapSize {
./Godeps/_workspace/src/github.com/boltdb/bolt/db.go:       sz = maxMapSize
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_windows.go: db.data = ((*[maxMapSize]byte)(unsafe.Pointer(addr)))
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_386.go:// maxMapSize represents the largest mmap size supported by Bolt.
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_386.go:const maxMapSize = 0x7FFFFFFF // 2GB
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_amd64.go:// maxMapSize represents the largest mmap size supported by Bolt.
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_amd64.go:const maxMapSize = 0xFFFFFFFFFFFF // 256TB
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_ppc64le.go:// maxMapSize represents the largest mmap size supported by Bolt.
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_ppc64le.go:const maxMapSize = 0xFFFFFFFFFFFF // 256TB
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_unix_solaris.go:    db.data = (*[maxMapSize]byte)(unsafe.Pointer(&b[0]))
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_arm64.go:// maxMapSize represents the largest mmap size supported by Bolt.
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_arm64.go:const maxMapSize = 0xFFFFFFFFFFFF // 256TB
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_s390x.go:// maxMapSize represents the largest mmap size supported by Bolt.
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_s390x.go:const maxMapSize = 0xFFFFFFFFFFFF // 256TB
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_arm.go:// maxMapSize represents the largest mmap size supported by Bolt.
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_arm.go:const maxMapSize = 0x7FFFFFFF // 2GB
./Godeps/_workspace/src/github.com/boltdb/bolt/bolt_unix.go:    db.data = (*[maxMapSize]byte)(unsafe.Pointer(&b[0]))

根据错误提示分析，是因为在 ./Godeps/_workspace/src/github.com/boltdb/bolt 文件夹下，
缺少了支持mips64le平台的文件。
进入这个目录下添加bolt_mips64le.go文件：

# cd ./Godeps/_workspace/src/github.com/boltdb/bolt
# cp bolt_arm.go  bolt_mips64le.go

重新进入etcd文件夹下，开始编译

# cd $GOPATH/src/github.com/coreos/etcd
# ./build

出现如下错误

2017-11-02 11:58:50.257747 E | etcdmain: etcd on unsupported platform without ETCD_UNSUPPORTED_ARCH=mips64le set.

这是因为没有配置ETCD_UNSUPPORTED_ARCH环境变量
配置环境变量

# export ETCD_UNSUPPORTED_ARCH=mips64le

再次编译

# ./build

执行通过，在etcd文件夹里会生成bin文件夹，进入bin文件夹

# cd bin

把bin文件夹下的etcd、etcdctl两个文件拷贝到/usr/bin文件夹下

# cp etcd  /usr/bin/
# cp etcdctl /usr/bin/

进入/usr/bin下

# cd /usr/bin

执行测试

执行etcd文件

# ./etcd

再另一个终端中测试

# etcdctl set /foo/bar  “hello world”

输出“hello world”说明启动成功。

这样，etcd就搭建成功了，整个过程还是很简单的，改动的代码不算多，运行也比较顺利。

后面将继续移植Kubernetes，好期待啊！
