安装步骤

# 安装常用的依赖包
yum  -y  install gcc gcc-c++ cmake make ncurses-devel  perl perl-develperl-DBD-MySQL

# mysql 5.7 安装需要用到boost
# 下载并解压到/usr/local/boost/
ls /usr/local/boost/

boost   boost-build.jam  boost.css  bootstrap.bat  doc   index.html  Jamroot  LICENSE_1_0.txt  rst.css  tools
boostcpp.jam     boost.png  bootstrap.sh   index.htm  INSTALL     libs     more             status

# 解压mysql5.7安装包
tar -xvf mysql-5.7.27.tar.gz
cd xvf mysql-5.7.27

# 编译安装
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql  -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock  -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_DATADIR=/home/mysql/DATA   -DMYSQL_USER=mysql   -DMYSQL_TCP_PORT=3306  -DWITH_BOOST=/usr/local/boost/
make
make install 


chown -R mysql:mysql /usr/local/mysql


#  mysql5.7 使用 mysqld --initialize 替代mysql5.6 的mysql_install_db 初始化数据库
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/home/mysql/DATA/ --explicit_defaults_for_timestamp
