篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用mysql5.7.16头文件库文件编译安装atlas相关的知识，希望对你有一定的参考价值。
最近mysql数据库升级到5.7.16，而中间件atlas之前是基于mysql5.6编译的，打算重新编译下atlas并使用mysql5.7.16的库文件头文件。这里主要介绍下编译过程遇到问题及解决方法。
由于需要glib版本要大于2.32以上，centos6.6系统自带的glib版本为2.28，因此需要重新编译安装2.32以上的glib，这里安装2.34版本的glib需要依赖pcre大于8.31
一、编译安装pcre8.35
# ./configure --prefix=/usr/local/glib --with-pcre=/usr/local/pcre/
# make
# make install
二、编译安装glib-2.34.3.tar.xz
# ./configure --prefix=/usr/local/glib --with-pcre=/usr/local/pcre/
# make
# make install
三、编译安装Atlas-2.2.1.tar.gz
1.解决依赖关系
# yum install libffi-devel lua-devel libevent libevent-devel jemalloc jemalloc-devel
2.修改源码中mysql版本代码，这里mysql版本为5.7.16
找到plugins/proxy/proxy-plugin.c文件
修改1974行：challenge->server_version_str = g_strdup("5.0.81-log");
为：challenge->server_version_str = g_strdup("5.7.16-log");
修改1974行：challenge->server_version = 50081;
为：challenge->server_version = 50716;
3.安装atlas
修改bootstrap.sh
#!/bin/sh base=$(cd "$(dirname "$0")"; pwd) cd $base PKG_CONFIG_PATH=/usr/local/glib/lib/pkgconfig ./configure --with-mysql=/usr/local/mysql5.7.16/bin/mysql_config --prefix=/usr/local/mysql-proxy CFLAGS="-DHAVE_LUA_H -O2" CPPFLAGS="-I/usr/local/mysql5.7.16/include/" LDFLAGS="-lm -ldl -lcrypto -ljemalloc" LUA_CFLAGS="-I/usr/include/" LUA_LIBS="-L/usr/lib64 -llua"
执行
# ./bootstrap.sh
# make && make install
4.执行make时会报错：
错误1：

报错原因：mysql5.7之后头文件中的CLIENT_SECURE_CONNECTION变量名修改为CLIENT_RESERVED2
cat /usr/local/src/mysql-5.6.17/include/mysql_com.h
cat /usr/local/src/mysql-5.7.16/include/mysql_com.h
5.解决方法：

7.导入mysql5.7库文件
# echo ‘/usr/local/mysql5.7.16/lib‘ >> /etc/ld.so.conf
# ldconfig
8.启动atlas
# /usr/local/mysql-proxy/bin/mysql-proxyd test start
