Atlas是360团队弄出来的一套基于MySQL-Proxy基础之上的代理，修改了MySQL-Proxy的一些BUG，并且优化了很多东西。

依赖包安装
****************************************************************************************
lua安装
-------------------------------------------
yum install -y libtermcap-devel ncurses-devel libevent-devel readline-devel
tar -zxvf lua-5.1.5.tar.gz
chown -R root.root *
cd lua-5.1.5/
修改当前目录下的“Makefile”中的 INSTALL_TOP= /usr/local为 INSTALL_TOP= /usr/local/lua
主要是为了避免与系统自带的lua库发生冲突的可能
vim Makefile
INSTALL_TOP= /usr/local/lua
make linux install
glib-2.49安装
----------------------------------------
rpm -q ncurses readline readline-devel lua libffi libffi-devel libiconv xz glib2 cmake popt libnl libevent libevent-devel openssl-devel libtermcap-devel ncurses-devel
yum install -y libffi-devel libtermcap-devel
http://www.rpmfind.net/linux/rpm2html/search.php?query=libevent-devel
rpm -ivh libevent-devel-2.0.21-4.el7.x86_64.rpm
libiconv依赖包
tar xvzf libiconv-1.14.tar.gz
chown -R root.root *
cd libiconv-1.14
cd srclib
sed -i -e '/gets is a security/d' ./stdio.in.h
cd ..
注意不要建立独立目录，一定要安装在/usr/local目录下，不然安装glib时会报/usr/bin/ld: cannot find -liconv
./configure --prefix=/usr/local gl_cv_header_working_stdint_h=yes
make
make install
pkg安装
tar -zxvf pkg-config-0.29.2.tar.gz

pcre安装
tar -zxvf pcre-8.39.tar.gz
chown -R root.root *
cd pcre-8.39/
./configure --enable-utf8 --enable-unicode-properties
make
make install
ln -s /usr/local/lib/libpcre.so.1 /lib

测试glib pkg
vim hello.c
#include <stdio.h>
#include <glib.h>
int main(int argc, char** argv){
GList* list=NULL;
list=g_list_append(list,"Hello world!");
list=g_list_append(list,"made by pcat");
list=g_list_append(list,"http://www.cnblogs.com/perfei/");
printf("The first item is %s\n",g_list_first(list)->data);
return 0;
}
编译如下：
gcc hello.c -o hello $(pkg-config --cflags --libs glib-2.0)
# ls -ltr | grep hello
-rw-r--r-- 1 root root 305 11月 20 16:47 hello.c

Atlas2.2.1 对应的是 mysql5.6 的版本，使用mysql5.7时需要进行以下调整
共四处需要替换，详见错误信息
vim src/network-mysqld-packet.c
:%s/CLIENT_SECURE_CONNECTION/CLIENT_RESERVED2/g
共一处需要替换，详见错误信息
vim ./plugins/admin/admin-plugin.c
:%s/CLIENT_SECURE_CONNECTION/CLIENT_RESERVED2/g
make
make如果报错处理，可进行以下处理
ln -s /usr/local/glib-2.49.7/lib/glib-2.0/include/glibconfig.h /usr/local/glib-2.49.7/include/glib-2.0
make install
----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/mysql-proxy/lib/mysql-proxy/plugins
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variableduring execution
- add LIBDIR to the `LD_RUN_PATH' environment variableduring linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
