对mysql的学习很有兴趣，为了深入的学习并且很好的在线上使用，在了解了去哪里关于开源inception的文档学习，一下为我的安装笔记与心得。
1，关于inception。
MySQL语句的审核，在业界都已经基本被认同了，实际上也是对MySQL语句写法的统一化，标准化，而之前的人工审核，针对标准这个问题其实是很吃力的，标准越多，DBA越累，开发也越累。
那么在这个都追求自动化运维的时代，审核也必须要跟上步伐，因此Inception诞生了。而Inception可以做的工作远不止是一个自动化审核工具，同时还具备执行，生成对影响数据的回滚语句（类似闪回的功能），这样一条龙服务的工具，将会给DBA的工作带来翻天覆地的变化，DBA从此就从繁重的审核、登上去执行，出错了很难回滚（如果提前没有备份的话）的被动局面解放了出来，突然发现，做DBA原来可以这么轻松，工作可以不饱和了，那就有更多的自由时间学习、进一步向自动化运维平台的实现等更智能化的方向去发展，是具有里程碑意义的。
2，inception架构原理。
3，安装inception。
实际上编译Inception，和编译MySQL源码是一样的。
（1）环境准备
#yum install -y gcc gcc-c++ make ncurses-devel bison openssl-devel zlib-devel cmake
（2）源码地址
#git clone https://github.com/mysql-inception/inception.git
（3）编译
#cmake -DWITH_DEBUG=OFF -DCMAKE_INSTALL_PREFIX=./mysql -DMYSQL_DATADIR=./mysql/data -DWITH_SSL=bundled -DCMAKE_BUILD_TYPE=RELEASE -DWITH_ZLIB=bundled -DMY_MAINTAINER_CXX_WARNINGS="-Wall -Wextra -Wunused -Wno-dev -Wwrite-strings -Wno-strict-aliasing -Wno-unused-parameter -Woverloaded-virtual" -DMY_MAINTAINER_C_WARNINGS="-Wall -Wextra -Wno-dev -Wunused -Wwrite-strings -Wno-strict-aliasing -Wdeclaration-after-statement"
#make
#make install
（4）启动inception。
#/usr/local/src/inception/mysql/bin/Inception
#netstat -antlp |grep ./Inception
tcp 0 0 :::3306 :::* LISTEN 16727/./Inception
（5）登录成功
#/usr/local/src/inception/mysql/bin/mysql
登录上去之后，再执行一个命令：
inception get variables;
