【DB】 Inception安装及配置

1. 安装依赖包

# rpm -qa | grep -E '^(cmake|ncurses|openssl|bison|gcc-c++)'
# yum install -y cmake ncurses-devel openssl-devel bison-devel gcc-c++ MySQL-python 

2. 安装Inception

    o 下载软件包

# wget https://github.com/weiyanwei412/SQLaudit/archive/master.zip
# unzip master.zip
# mv SQLaudit-master /opt/inception-master
# cd /opt/inception-master

    o 编译安装

# cmake -DWITH_DEBUG=OFF \
-DCMAKE_INSTALL_PREFIX=/usr/local/inception \
-DMYSQL_DATADIR=/usr/local/inception/data \
-DWITH_SSL=yes \
-DCMAKE_BUILD_TYPE=RELEASE \
-DWITH_ZLIB=bundled \
-DMY_MAINTAINER_C_WARNINGS="-Wall -Wextra -Wunused -Wwrite-strings -Wno-strict-aliasing -Wdeclaration-after-statement" \
-DMY_MAINTAINER_CXX_WARNINGS="-Wall -Wextra -Wunused -Wwrite-strings -Wno-strict-aliasing -Wno-unused-parameter -Woverloaded-virtual"
# make && make install

    o 配置文件

# vi /etc/inc.cnf
# doc: https://github.com/weiyanwei412/inception-document/blob/master/docs/variables.md
