有过MySQL运维的人应该都清楚，线上的MySQL一般都采用源码编译，因为这样才可以根据企业的各自需要选择要编译的功能，虽然MySQL的源码编译挺简单的，但是试想一下，如果你有几百台服务器同时要安装MySQL，难道你还一台台去手动编译、编写配置文件吗？这显然太低效了，本文讨论MySQL的自动化安装部署。
1、制作符合自己需求的RPM包
我们要根据MySQL的源码编译符合企业需求的RPM包，源码获取命令如下：
wget http://downloads.mysql.com/archives/get/file/mysql-5.6.16.tar.gz
tar -zxvf mysql-5.6.16.tar.gz
cd mysql-5.6.16
mkdir rpm
cd rpm
在上面我们获取了源码，并在源码主目录下创建rpm目录，接着我们在该目录下创建mysql.spec文件：
Name: mysql
Version:5.6.16
Release: guahao
License: GPL
URL: http://downloads.mysql.com/archives/get/file/mysql-5.6.16.tar.gz
Group: applications/database
BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root
BuildRequires: cmake
Packager: zhuxj@guahao.com
Autoreq: no
prefix: /opt/mysql
Summary: MySQL 5.6.16
%description
The MySQL(TM) software delivers a very fast, multi-threaded, multi-user,
and robust SQL (Structured Query Language) database server. MySQL Server
is intended for mission-critical, heavy-load production systems as well
as for embedding into mass-deployed software.
%define MYSQL_USER mysql
%define MYSQL_GROUP mysql
%define __os_install_post %{nil}
%build
cd $OLDPWD/../

make -j `cat /proc/cpuinfo | grep processor| wc -l`
%install
cd $OLDPWD/../
make DESTDIR=$RPM_BUILD_ROOT install
%clean
rm -rf $RPM_BUILD_ROOT
%files
%defattr(-, %{MYSQL_USER}, %{MYSQL_GROUP})
%attr(755, %{MYSQL_USER}, %{MYSQL_GROUP}) %{prefix}/*
%pre
%post
ln -s %{prefix}/lib %{prefix}/lib64
%preun
%changelog
有了这个spec文件之后，就可以执行如下命令生成我们自己的RPM包：
rpmbuild -bb ./mysql.spec
2、编写my.cnf模板
my.cnf模板如下：
[mysqld_safe]
pid-file=/opt/mysql/run/mysqld.pid
[mysql]
prompt=\\u@\\d \\r:\\m:\\s>
default-character-set=gbk
no-auto-rehash
[client]
socket=/opt/mysql/run/mysql.sock
[mysqld]
#dir
basedir=/opt/mysql
datadir=/data/mysql/data
tmpdir=/data/mysql/tmp
log-error=/data/mysql/log/alert.log
slow_query_log_file=/data/mysql/log/slow.log
general_log_file=/data/mysql/log/general.log
socket=/opt/mysql/run/mysql.sock
#innodb
innodb_data_home_dir=/data/mysql/data
innodb_log_group_home_dir=/data/mysql/data
innodb_data_file_path=ibdata1:2G;ibdata2:16M:autoextend
innodb_buffer_pool_size=10G
