CentOS6.6 x64位，MySQL5.7安装mydumper

第一步：下载安装包

下载链接：

https://launchpad.net/mydumper/0.6/0.6.2/+download/mydumper-0.6.2.tar.gz

第二步：安装依赖包

Mydumper安装有很多依赖包，需要提前安装好

yum install cmake glib2-devel mysql-devel zlib-devel pcre-devel openssl-devel

第三步：解压及安装

通常这一步会碰到很多问题，先说步骤：

1.解压到/usr/local/下并创建软连接

tar -zxvf mydumper-0.6.2.tar.gz -C /usr/local/cd /usr/localln -sv mydumper-0.6.2 mydumper

创建连接是为了更好地管理软件包，方便升级等操作

2.编辑及安装

cd /usr/local/mydumpercmake .make make install

通常问题都出在这里：

（1）编译器错误：

CMake Error: your C compiler: "CMAKE_C_COMPILER-NOTFOUND" was not found.   Please set CMAKE_C_COMPILER to a valid compiler path or name.CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.   Please set CMAKE_CXX_COMPILER to a valid compiler path or name.

显示错误，cmake编译器发生错误，这里并不是cmake并身问题，是C编译器没找到，需要安装：

yum install -y gcc-c++

再运行cmake 这个错误消除了

（2）环境变量配置

mydumper安装过程并不需要配置多余的参数，出现这种问题通常是因为之前解压目录里有老的编译文件，再次编译时出了问题：

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.Please set them or make sure they are set and tested correctly in the CMake files:MYSQL_LIBRARIES_dl    linked by target "mydumper" in directory /root/mydumper-0.6.2    linked by target "myloader" in directory /root/mydumper-0.6.2MYSQL_LIBRARIES_m    linked by target "mydumper" in directory /root/mydumper-0.6.2    linked by target "myloader" in directory /root/mydumper-0.6.2MYSQL_LIBRARIES_mysqlclient    linked by target "mydumper" in directory /root/mydumper-0.6.2    linked by target "myloader" in directory /root/mydumper-0.6.2MYSQL_LIBRARIES_pthread    linked by target "mydumper" in directory /root/mydumper-0.6.2    linked by target "myloader" in directory /root/mydumper-0.6.2MYSQL_LIBRARIES_rt    linked by target "mydumper" in directory /root/mydumper-0.6.2    linked by target "myloader" in directory /root/mydumper-0.6.2

这时解决方法了很简单：重新解压再编译安装就可以。
