使用go-mysql-elasticsearch将mysql实时同步到es

GRANT REPLICATION SLAVE ON *.* TO 'elastic'@'127.0.0.1'; 
GRANT RELOAD ON *.* TO 'elastic'@'127.0.0.1'; 
UPDATE mysql.user SET Super_Priv='Y' WHERE user='elastic' AND host='127.0.0.1';

1.安装golang

下载地址 https://studygolang.com/dl

2.下载go-mysql-elasticsearch

下载地址 https://github.com/siddontang/go-mysql-elasticsearch

或者通过git

git clone https://github.com/siddontang/go-mysql-elasticsearch

cd go-mysql-elasticsearch
 make
 vi etc/river.toml

配置以下内容

# MySQL address, user and password
# user must have replication privilege in MySQL.
my_addr = "127.0.0.1:3306"
my_user = "root"
my_pass = "root"
my_charset = "utf8"

# Set true when elasticsearch use https
#es_https = false
# Elasticsearch address
es_addr = "127.0.0.1:9200"
# Elasticsearch user and password, maybe set by shield, nginx, or x-pack
es_user = ""
es_pass = ""

# 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 = "./var"

# Inner Http status address
stat_addr = "127.0.0.1:12800"

# pseudo server id like a slave
server_id = 1001

# mysql or mariadb
flavor = "mysql"

# mysqldump execution path
# if not set or empty, ignore mysqldump.
#mysqldump = "mysqldump"
mysqldump='/usr/local/mysql-8.0.16-macos10.14-x86_64/bin/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 = "mmmdb"

# 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 = ["t", "t_[0-9]{4}", "tfield", "tfilter"]
tables=["user"]

[[rule]]
schema = "mmmdb"
table = "user"
index = "mmmdb"
type = "user"

[[rule.fields]]
name="name"
age="age"
sex="sex"

配置完成后执行

./bin/go-mysql-elasticsearch -config=./etc/river.toml

现在可以尝试操作mysql数据库，发现已经实时同步到es
