1、创建 mysql 用户，用户组，以及相关目录
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
mkdir -p /opt/local/mysql/data
mkdir -p /opt/local/mysql/binlog
mkdir -p /opt/local/mysql/logs
mkdir -p /opt/local/mysql/relaylog
mkdir -p /var/lib/mysql
mkdir -p /opt/local/mysql/etc
2、下载 Mysql 5.7 最新版本的 tar.gz 文件
前往如下地址选择下载：
ftp://ftp.mirrorservice.org/sites/ftp.mysql.com/Downloads/MySQL-5.7/
3、安装相关依赖
yum -y install cmake ncurses ncurses-devel bison bison-devel boost boost-devel
4、解压，编译mysql
tar zxvf mysql-5.7.11.tar.gz
cd mysql-5.7.11
cmake -DCMAKE_INSTALL_PREFIX="/opt/local/mysql" -DDEFAULT_CHARSET=utf8 -DMYSQL_DATADIR="/opt/local/mysql/data/" -DCMAKE_INSTALL_PREFIX="/opt/local/mysql" -DINSTALL_PLUGINDIR=plugin -DWITH_INNOBASE_STORAGE_ENGINE=1 -DDEFAULT_COLLATION=utf8_general_ci -DENABLE_DEBUG_SYNC=0 -DENABLED_LOCAL_INFILE=1 -DENABLED_PROFILING=1 -DWITH_ZLIB=system -DWITH_EXTRA_CHARSETS=none -DMYSQL_MAINTAINER_MODE=OFF -DEXTRA_CHARSETS=all -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost
( -DDOWNLOAD_BOOST=1 会自动下载boost 到 DWITH_BOOST= 指定目录 或者自行下载，存放于指定目录 )
make -j `cat /proc/cpuinfo | grep processor| wc -l`
make install
ln -s /opt/local/mysql/lib/mysql /usr/lib/mysql
ln -s /opt/local/mysql/include/mysql /usr/include/mysql
ln -s /opt/local/mysql/bin/mysql /usr/bin/mysql
ln -s /opt/local/mysql/bin/mysqldump /usr/bin/mysqldump
ln -s /opt/local/mysql/bin/myisamchk /usr/bin/myisamchk
ln -s /opt/local/mysql/bin/mysqld_safe /usr/bin/mysqld_safe
ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock
rm -rf /etc/my.cnf
cp /opt/local/mysql/support-files/my-default.cnf /opt/local/mysql/etc/my.cnf
cd /opt/local/mysql/bin/
./mysqld --initialize --user=mysql --basedir=/opt/local/mysql --datadir=/opt/local/mysql/data
会生成一个root 的 随机密码，请务必先记录一下。如果忘记了，请查看 ( /opt/local/mysql/logs/mysqld.log )
chmod +w /opt/local/mysql
chown -R mysql:mysql /opt/local/mysql
chmod +w /var/lib/mysql
chown -R mysql:mysql /var/lib/mysql
cp /opt/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
echo 'basedir=/opt/local/mysql/' >> /etc/init.d/mysqld
echo 'datadir=/opt/local/mysql/data' >>/etc/init.d/mysqld
service mysqld start
/opt/local/mysql/bin/mysql_secure_installation -uroot -p
