缺点：后期升级不方便，生产中建议RPM包方式安装
CentOS7默认安装了和MySQL有兼容性的MariaDB数据库，在我们安装MySQL5.7之前为了避免发生冲突首先删除MariaDB。
# rpm -qa | grep maria
# yum remove mariadb-libs -y
一、基于官方源码包安装
下载 mysql-5.7.22.tar.gz
安装cmake
# yum -y install cmake
# tar -zxvf mysql-5.7.22.tar.gz -C /usr/src
# cd /usr/src/mysql-5.7.22
# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/var/lib/mysql -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DMYSQL_UNIX_ADDR=/tmp/mysqld.sock -DENABLED_LOCAL_INFILE=1 -DWITH_EXTRA_CHARSETS=all -DMYSQL_USER=mysql

解决：下载boost_1_59_0.tar.gz，放在/usr/local/boost下

CMake Error at cmake/readline.cmake:64 (MESSAGE):
Curses library not found. Please install appropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on RedHat and derivates it is ncurses-devel.

-- Configuring incomplete, errors occurred!
解决：
#yum -y install ncurses-devel
# rm -rf /usr/src/mysql-5.7.22/CMakeCache.txt
# gmake
# make install
安装之后的一些配置：
# cd /usr/local/mysql/support-files/
]# ll mysql.server
-rwxr-xr-x 1 root root 10569 Apr 20 11:11 mysql.server
# cp mysql.server /etc/init.d/mysql
# cd /var/lib/
# mkdir mysql
# chown mysql. mysql
# vi /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql
datadir = /var/lib/mysql
port = 3306
socket = /tmp/mysqld.sock
mysql_install_db 被废弃了，取而代之的是 mysqld –initialize
# /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize --datadir=/var/lib/mysql --basedir=/usr/local/mysql --user=mysql
