1.依赖包安装:
yum -y install gcc gcc-c++ cmake ncurses-devel autoconf perl perl-devel
2.创建mysql安装目录以及数据存放目录
mkdir -p /usr/local/mysql/data
3.创建用户、用户组
groupadd mysql
useradd -r -g mysql mysql
4.开始安装
tar -zxvf mysql-5.7.20.tar.gz
进入 cd mysql-5.7.20
# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DINSTALL_DATADIR=/usr/local/mysql/data \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=all \
-DENABLED_LOCAL_INFILE=1
注意：
CMake Error at cmake/boost.cmake:81 (MESSAGE): You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST= This CMake script will look for boost in . If it is not there, it will download and unpack it (in that directory) for you. If you are inside a firewall, you may need to use an http proxy: export http_proxy=http://example.com:80 Call Stack (most recent call first): cmake/boost.cmake:238 (COULD_NOT_FIND_BOOST) CMakeLists.txt:455 (INCLUDE) -- Configuring incomplete, errors occurred!

如果出错缺少boots请先安装
解决办法是：
1.在/usr/local下创建一个名为boost的文件夹
mkdir -p /usr/local/boost
2.进入这个新创建的文件夹然后下载boost
wget http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
3.解压
tar -xvzf boost_1_59_0.tar.gz
4.继续cmake，添加上红色部分
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DCOMPILATION_COMMENT='Mysqlma' \
-DWITH_READLINE=ON \
-DWITH_BOOST=/usr/local/boost \
-DSYSCONFDIR=/data/mysqldata/3306 \
-DMYSQL_UNIX_ADDR=/data/mysqldata/3306/mysql.sock
以上执行完在mysql目录下执行make（以上操作时间比较漫长，安装大约20分钟左右）
检查系统是否已经有mysql用户，如果没有则创建
mysql 初始化数据库
