1、安装GO环境

安装go

\#yum install -y go

安装godep

\#go get github.com/tools/godep

2、MySQL开启binlog

Mysql必须开启binlog(binlog-format=ROW, binlog\_row\_image = FULL);

要赋予用于连接mysql的账户RELOAD权限以及REPLICATION权限, SUPER权限;

\#GRANT REPLICATION SLAVE ON \*.\* TO ’数据库账号'@'%';

\#GRANT REPLICATION CLIENT ON \*.\* TO '数据库账号'@'%';

\#GRANT RELOAD ON \*.\* TO '数据库账号'@'%';

\#UPDATE mysql.\`user\` SET Super\_Priv = 'Y' WHERE USER = '数据库账号' AND HOST = '%';

3、安装GO依赖包

\#vim /etc/profile

底部添加：

export GOPROXY=https://goproxy.io

设置生效

\#source /etc/profile

4、下载go-mysql-elasticsearch代码包

下载go-mysql-elastisearch插件

\#go get github.com/siddontang/go-mysql-elasticsearch

进入对应目录，比如我使用的如下目录/root/go/src/github.com/siddontang/go-mysql-elasticsearch

\#cd /root/go/src/github.com/siddontang/go-mysql-elasticsearch

编译

\#make

5、mysqldump安装及配置

\#yum -y install holland-mysqldump.noarch

mysqldump备份简单操作：

\#mysqldump -h\[ip\] -P\[端口号\]  -u\[用户名\]  -p 数据库名 表名 >导出的文件名.sql

\#mysqldump -h\[ip\] -P\[端口号\]  -u\[用户名\]  -p 数据库名 表名1 表名2 表名3 | gzip >导出的文件名.sql.gz

例如：mysqldump -h127.0.0.1 -P 3306 -u root -p db\_name table\_name >/data/xxx.sql(回车输入密码)

6、配置go-mysql-elasticsearch

\#vim etc/river.toml

================================================

\# MySQL address, user and password

\# user must have replication privilege in MySQL.

my\_addr = "CHANGEME"\#数据库ip:端口

my\_user = "CHANGEME"\#数据库账号

my\_pass = "CHANGEME"\#数据库密码

my\_charset = "utf8"

\# Set true when elasticsearch use https

\#es\_https = false

\# Elasticsearch address

es\_addr = "CHANGEME"\#ES库ip:端口

\# Elasticsearch user and password, maybe set by shield, nginx, or x-pack

es\_user = "CHANGEME"\#es账号

es\_pass = "CHANGEME"\#es密码

\# Path to store data, like master.info, if not set or empty,

\# we must use this to support breakpoint resume syncing.

\# TODO: support other storage, like etcd.

data\_dir = "./devdata"

\# Inner Http status address

stat\_addr = "127.0.0.1:12800"

stat\_path = "/metrics"

\# pseudo server id like a slave

server\_id = 3001

\# mysql or mariadb

flavor = "mysql"

\# mysqldump execution path

\# if not set or empty, ignore mysqldump.

mysqldump = "mysqldump"

\# if we have no privilege to use mysqldump with --master-data,

\# we must skip it.

\#skip\_master\_data = false

\# minimal items to be inserted in one bulk

bulk\_size = 128

\# force flush the pending requests if we don't have enough items >= bulk\_size

flush\_bulk\_time = "200ms"

\# Ignore table without primary key

skip\_no\_pk\_table = false

\# MySQL data source

\[\[source\]\]

schema = "CHANGEME"\#数据库库名

\# Only below tables will be synced into Elasticsearch.

\# "t\_\[0-9\]\{4\}" is a wildcard table format, you can use it if you have many sub tables, like table\_0000 - table\_1023

\# I don't think it is necessary to sync all tables in a database.

tables = \["CHANGEME"\]\#数据库表

\# Below is for special rule mapping

\# Very simple example

\# desc t;

\# +-------+--------------+------+-----+---------+-------+

\# +-------+--------------+------+-----+---------+-------+

\# | id    | int(11)      | NO   | PRI | NULL    |       |

\# +-------+--------------+------+-----+---------+-------+

\# The table \`t\` will be synced to ES index \`test\` and type \`t\`.

\[\[rule\]\]

schema = "CHANGEME"\#数据库库名

table = "CHANGEME"\#数据库表

index = "CHANGEME"\#ES库索引

type = "CHANGEME"\#ES库类型

================================================

7、运行

\#rm -f var/master.info

\#nohup bin/go-mysql-elasticsearch -config=river.toml &

8、使用head检测

chrome浏览器安装head插件直接使用。
