1.系统要求
mount /dev/cdrom /mnt
yum install -y cmake,make,gcc,gcc-c++,bison, ncurses,ncurses-devel
2.创建用户和组
groupadd mysql
useradd -g mysql mysql
3.创建数据库安装目录
mkdir /mysql /mysql/data /mysql/log
chown -R mysql:mysql /mysql
/mysql/data --数据库目录
/mysql/log --错误日志和慢查询日志
4.解压源码文件和boost文件
cd /usr/local
tar -zxvf mysql-5.7.19.tar.gz
tar -zxvf boost_1_59_0.tar.gz
cd /usr/local/mysql-5.7.19

5.编译生成MakeFile文件
cmake . \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/mysql/data \
-DDEFAULT_CHARSET=utf8mb4 \
-DDEFAULT_COLLATION=utf8mb4_general_ci \

6.编译和安装
make
make install
7.配置开机启动项
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
chmod +x /etc/init.d/mysql
chkconfig --add mysql
chkconfig mysql on
8.配置文件
cat > /etc/my.cnf << EOF

9.初始化安全安装
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/data
注： 之前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目录下,且已被废弃
“-initialize”会生成一个随机密码(~/.mysql_secret)，而”-initialize-insecure”不会生成密码
–datadir目标目录下不能有数据文件
10.启动数据库
service mysql start
11.修改密码
update mysql.user set authentication_string=password('root') where user = 'root';
flush privileges;
12.关闭防火墙和selinux
service iptables stop
chkconfig iptables off
vi /etc/selinux/config
SELINUX=disabled
