一、首先在Centos6.5上安装 go 语言环境
下载Golang语言包：https://studygolang.com/dl
1 [hoojjack@localhost src]$ ls 2 apache-maven-3.5.0 go go1.6.2.linux-amd64.tar.gz
二、解压.tar.gz安装包。
三、配置安装环境。
[hoojjack@localhost etc]$ vim profile export GOPATH=/usr/local/src/go/work export GOROOT=/usr/local/src/go export PATH=$GOPATH/bin:$PATH
GOARCH（指定系统环境，i386表示x86，amd64表示x64）：amd64
GOROOT：/usr/local/src/go（go的解压路径）
GOBIN：%GOROOT%/bin（exe执行文件路径）
GOOS：（go运行的系统）
GOPATH：/usr/local/src/go/work（用于存放Go语言Package的目录，这个目录不能在Go的安装目录中，放了好像也没什么事，至少我目前没事 ^_^）
我们需要添加的环境变量分别是go的安装路径GOROOT：/usr/local/src/go，PATH：$GOROOT/bin:$PATH，go的工作路径GOPATH:/usr/local/src/go/work
四、配置go环境后配置go-mysql-elasticsearch
首先确保环境中安装了git
安装依赖包：
sudo yum install gettext-devel openssl-devel perl-CPAN perl-devel zlib-devel
也可以直接用yum命令安装：
yum install git
然后：
获取安装包：go get github.com/siddontang/go-mysql-elasticsearch
安装：
cd $GOPATH/src/github.com/siddontang/go-mysql-elasticsearch
make
1 [hoojjack@localhost etc]$ cd /usr/local/src/go/src/github.com/siddontang/go-mysql-elasticsearch 2 [hoojjack@localhost go-mysql-elasticsearch]$ ls 3 bin cmd elastic etc Godeps LICENSE Makefile README.md river var 4 [hoojjack@localhost go-mysql-elasticsearch]$
五、修改配置文件
1 # MySQL address, user and password 2 # user must have replication privilege in MySQL. 3 my_addr = "127.0.0.1:3306" //需要同步的mysql基本设置 4 my_user = "root" 5 my_pass = "root" 6 7 # Elasticsearch address 8 es_addr = "127.0.0.1:9200" //本地elasticsearch配置 9 10 # Path to store data, like master.info, and dump MySQL data 11 data_dir = "./var" //数据存储的url 12 //以下配置保存默认不变 13 # Inner Http status address 14 stat_addr = "127.0.0.1:12800" 15 16 # pseudo server id like a slave 17 server_id = 1001 18 19 # mysql or mariadb 20 flavor = "mysql" 21 # mysqldump execution path 22 mysqldump = "mysqldump" 23 24 # MySQL data source 25 [[source]] 26 schema = "hoojjack" //elasticsearch 与 mysql 同步时对应的数据库名称 27 28 # Only below tables will be synced into Elasticsearch. 29 # "test_river_[0-9]{4}" is a wildcard table format, you can use it if you have many sub tables, like table_0000 - table_1023 30 # I don't think it is necessary to sync all tables in a database. 31 tables = ["test_river", "test_river_[0-9]{4}"] //支持通配符，可以指定只复制hoojjack数据库中指定的表数据 32 33 # Below is for special rule mapping 34 [[rule]] 35 schema = "hoojjack" //数据库名称 36 table = "test_river" //表名称 37 index = "river" //对应的索引名称 38 # title is MySQL test_river field name, es_title is the customized name in Elasticsearch 39 [rule.field] 40 # This will map column title to elastic search my_title 41 title="es_title" //将可以将mysql的某个属性对应指向elasticsearch的某个field, 如test_river的titile属性对应es_title 42 # This will map column tags to elastic search my_tags and use array type 43 tags="my_tags,list" 44 # This will map column keywords to elastic search keywords and use array type 45 keywords=",list" 46 47 # wildcard table rule, the wildcard table must be in source tables 48 [[rule]] 49 schema = "hoojjack" 50 table = "test_river_[0-9]{4}" 51 index = "river" 52 type = "river" 53 54 # title is MySQL test_river field name, es_title is the customized name in Elasticsearch 55 [[rule.fields]] 56 mysql = "title" 57 elastic = "es_title"
六、执行go-mysql-elasticsearch同步，首先进入 go-mysql-elasticsearch 路径，然后执行 ： ./bin/go-mysql-elasticsearch -config=./etc/river.toml
1 cd $GOPATH/src/github.com/siddontang/go-mysql-elasticsearch 2 ./bin/go-mysql-elasticsearch -config=./etc/river.toml
效果如下：
mysql> select * from test_river;
+----+-----------+-----------------+--------+
| id | name | title | number |
+----+-----------+-----------------+--------+
| 1 | hoojjack | wo shi yi bing | 1 |
| 2 | xunchuan | ni shi er ren | 2 |
七、出现的问题：
1、mysqldump: command not found
mysql的mysqldump命令没有找到，解决办法：创建软连接，查看mysqldump是在哪个路径下：find / -name mysqldump 会获得路径，然后创建软连接：ln -s /usr/local/mysql/bin/mysqldump /usr/bin
这是由于系统默认会查找/usr/bin下的命令，如果这个命令不在这个目录下，当然会找不到命令
如果没有安装mysql，则可以利用yum安装mysql5.6
1）检查系统是否安装其他版本的MYSQL数据
#yum list installed | grep mysql #yum -y remove mysql-libs.x86_64
2）安装及配置
# wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm # rpm -ivh mysql-community-release-el6-5.noarch.rpm # yum repolist all | grep mysql
3）安装MYSQL数据库
yum install mysql-community-server -y
2、make build go-mysql-elasticsearch项目的时候出现问题（can’t load package: package .: no buildable Go source files in ）
网上有很多的解决方法，但是我都没看懂，唯一看懂的大概就是要升级下go版本，因为之前go是1.6的，索性尝试升级到1.10，后面问题解决了（人品大爆棚），但是问题的核心没有解决。啊啊。。
