mysql发布5.7已经很久了，速度方面据说有提升。我们今天来编译安装mysql5.7,mysql目录/home/mysql,data目录/home/mysql/data,有些人喜欢放到/usr/local/mysql,当然你也可以自定义，相当方便的,测试环境为centos6.10 64位
mysql版本:5.7.24你也可以去官方下载最新版本:https://dev.mysql.com/downloads/mysql/5.7.html#downloads
下载boost 版本:1.59.0,址:https://sourceforge.net/projects/boost/files/boost/，boost安装于/usr/local/boost
安装支持组件:yum -y install wget gcc gcc-c++ autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* make cmake libaio libaio-devel autoconf bzr bison libtool
wget --no-check-certificate https://nchc.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz
wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.24.tar.gz
tar -xzvf boost_1_59_0.tar.gz
mkdir -p /home/mysql/
mv boost_1_59_0 /home/mysql
cd /home/mysql
mv boost_1_59_0 boost
cd /root
groupadd -r mysql
useradd -g mysql -r -M -s /sbin/nologin mysql
mkdir -p /home/mysql 
chown -R mysql:mysql /home/mysql
tar -zxvf mysql-5.7.24.tar.gz
cd mysql-5.7.24
cmake -DCMAKE_INSTALL_PREFIX=/home/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_USER=mysql -DMYSQL_TCP_PORT=3306 -DWITH_BOOST=/home/mysql/boost/
make && make install
初始化
cd /home/mysql/bin
./mysqld --initialize --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data
这时会产生一个密码--记下来，这个是root密码
vi /etc/my.cnf
