篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Mysql Atlas 安装记录相关的知识，希望对你有一定的参考价值。

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
chown -R root.root *
cd pkg-config-0.29.2/
./configure --enable-iconv=no --with-libiconv=gnu --with-internal-glib
make
make install

ln -s /usr/local/lib/libiconv.so.2 /usr/lib/libiconv.so.2
ln -s /usr/local/lib/libiconv.so.2 /usr/lib64/libiconv.so.2
pkg-config --version
0.29.2

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
ln -s /usr/local/lib/libpcreposix.so.0 /lib

glib安装
rpm -q libffi-devel
xz -d glib-2.49.7.tar.xz
chown -R root.root *
tar -xvf glib-2.49.7.tar

mkdir /usr/local/glib-2.49.7
cd glib-2.49.7/
./configure --prefix=/usr/local/glib-2.49.7 --with-libiconv=gnu LIBFFI_CFLAGS="-I/usr/local/include" LIBFFI_LIBS="-L/usr/local/lib -lffi"
make
make install

配置PKG-CONFIG
# find /usr/ -name pkgconfig
/usr/lib64/pkgconfig
/usr/share/pkgconfig
/usr/local/lib/pkgconfig
/usr/local/lib64/pkgconfig
/usr/local/mysql/lib/pkgconfig
/usr/local/glib-2.49.7/lib/pkgconfig

# cd /usr/local/glib-2.49.7/lib/pkgconfig
# ls
gio-2.0.pc gio-unix-2.0.pc glib-2.0.pc gmodule-2.0.pc gmodule-export-2.0.pc gmodule-no-export-2.0.pc gobject-2.0.pc gthread-2.0.pc

vim .bash_profile
export PKG_CONFIG_PATH=/usr/local/glib-2.49.7/lib/pkgconfig:/usr/lib64/pkgconfig:/usr/local/lib64/pkgconfig:/usr/local/mysql/lib/pkgconfig:$PKG_CONFIG_PATH
. ./.bash_profile

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
-rwxr-xr-x 1 root root 8648 11月 20 17:05 hello

# ./hello
The first item is Hello world!

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.
