一个集审核、执行、备份及生成回滚语句于一身的MySQL自动化运维工具,由去哪网开源
安装
- CentOS 7
- Python 3.6
安装基础环境
yum -y install cmake libncurses5-dev libssl-dev g++ bison gcc gcc-c++ openssl-devel ncurses-devel mysql pymysql

注意bison版本，centos7如果yum安装bison，会因为版本过高导致编译报错
wget http://ftp.gnu.org/gnu/bison/bison-2.5.1.tar.gz
tar -zxvf bison-2.5.1.tar.gz
cd bison-2.5.1
./configure
make
make install
安装 inception
cd /usr/local/
wget https://github.com/mysql-inception/inception/archive/master.zip
unzip master.zip
cd inception-master/
sh inception_build.sh builddir linux
修改配置
cat /etc/inc.cnf

使用
对sql的审核都是在脚本中调用inception去实现的,下面就简单使用下
准备脚本
(inception_env) [vagrant@localhost ~]$ cat test.py
#!/usr/bin/python
#-\*-coding: utf-8-\*-
''' 建库建表语句
CREATE DATABASE test;
CREATE TABLE IF NOT EXISTS `mytable1`(
`id` INT UNSIGNED AUTO_INCREMENT,
`myname` VARCHAR(10) NOT NULL,
PRIMARY KEY ( `id` )
)ENGINE=InnoDB DEFAULT CHARSET=utf8;
'''
import pymysql
# 待审核/执行的sql语句（需包含目标数据库的地址、端口 等参数）
sql='/* --user=root;--password=123456;--host=127.0.0.1;--port=3306;--enable-check; */\
inception_magic_start;\
use test;\
insert into mytable1 (myname) values ("xianyu1"),("xianyu2");\
insert into mytable1 (myname) values ("xianyu1"),("xianyu2");\
inception_magic_commit;'
try:
# inception的地址、端口等
conn=pymysql.connect(host='127.0.0.1',user='root',passwd='123456',db='',port=6669)
cur=conn.cursor()
ret=cur.execute(sql)
result=cur.fetchall()
num_fields = len(cur.description)
field_names = [i[0] for i in cur.description]
print (result)
'''
for row in result:
print row[0], "|",row[1],"|",row[2],"|",row[3],"|",row[4],"|",
row[5],"|",row[6],"|",row[7],"|",row[8],"|",row[9],"|",row[10]
'''
cur.close()
conn.close()
except Exception as e:
print (e)
注意:
- --enable-check是审核sql
- --enable-execute是执行sql
具体指令参考官方文档
http://mysql-inception.github.io/inception-document/
如果就这样直接执行是会报如下错误的
invalid literal for int() with base 10: 'Inception2'
因为inception是不支持python3的pymysql库的，所以得修改下pymysql的源码才行
查找pymysql源码修改connections.py文件
找到_request_authentication方法
def _request_authentication(self):
# https://dev.mysql.com/doc/internals/en/connection-phase-packets.html#packet-Protocol::HandshakeResponse
if int(self.server_version.split('.', 1)[0]) >= 5:
self.client_flag |= CLIENT.MULTI_RESULTS
修改为
def _request_authentication(self):
# https://dev.mysql.com/doc/internals/en/connection-phase-packets.html#packet-Protocol::HandshakeResponse
try:
if int(self.server_version.split('.', 1)[0]) >= 5:
self.client_flag |= CLIENT.MULTI_RESULTS
except:
if self.server_version.split('.', 1)[0] == 'Inception2':
self.client_flag |= CLIENT.MULTI_RESULTS
现在我们来执行下脚本看看
(inception_env) [vagrant@localhost ~]$ python test.py
((1, 'CHECKED', 0, 'Audit completed', 'None', 'use test', 0, "'0_0_0'", 'None', '0', ''), (2, 'CHECKED', 0, 'Audit completed', 'None', 'insert into mytable1 (myname) values ("xianyu1"),("xianyu2")', 2, "'0_0_1'", '127_0_0_1_3306_test', '0', ''), (3, 'CHECKED', 0, 'Audit completed', 'None', 'insert into mytable1 (myname) values ("xianyu1"),("xianyu2")', 2, "'0_0_2'", '127_0_0_1_3306_test', '0', ''))
可以看到sql审核过了(Audit completed)，没有问题，那来执行sql看看(把脚本里的--enable-check改成--enable-execute)
(inception_env) [vagrant@localhost ~]$ python test.py
((1, 'RERUN', 0, 'Execute Successfully', 'None', 'use test', 0, "'1533472093_33_0'", 'None', '0.000', ''),
(2, 'EXECUTED', 0, 'Execute Successfully\nBackup successfully', 'None', 'insert into mytable1 (myname) values ("xianyu1"),("xianyu2")', 2, "'1533472093_33_1'", '127_0_0_1_3306_test', '0.010', ''), (3, 'EXECUTED', 0, 'Execute Successfully\nBackup successfully', 'None', 'insert into mytable1 (myname) values ("xianyu1"),("xianyu2")', 2, "'1533472093_33_2'", '127_0_0_1_3306_test', '0.000', ''))
可以看到(Execute Successfully\nBackup successfully)sql执行成功并且被备份了回滚语句
开启数据库binlog选项(不开启的话是不会生成备份库的)
cat /etc/my.cnf
[mysqld]
log-bin = mysql-bin
binlog_format = ROW
server-id = 1
我们去看看(备份的数据在配置文件指定的库里)
(inception_env) [root@localhost bin]# mysql -uroot -h127.0.0.1 -p123456
