源码安装MySQL比较麻烦，需要安装依赖包，然后进行编译，时间较长，建议安装二进制的MySQL，时间比较快；
用到的软件包：
mysql-5.7.18.tar.gz
boost_1_59_0.tar.gz
1、安装依赖包
yum -y install gcc* gcc-c++ ncurses* ncurses-devel* cmake* bison* libgcrypt* perl*
2、创建MySQL用户：
[root@localhost ~]# mkdir -p /mysql/data
[root@localhost ~]# mkdir -p /mysql/mysql5718
[root@localhost ~]# chown -R mysql.mysql /mysql/
3、调整系统参数
[root@localhost ~]# vim /etc/security/limits.conf
* soft nproc 65535
* hard nproc 65535
* soft nofile 65535
* hard nofile 65535
[root@localhost ~]# vi /etc/security/limits.d/20-nproc.conf
* soft nproc 65535
[root@localhost ~]# vi /etc/profile
ulimit -u 65535
ulimit -n 65535
4、下载并解压软件
[root@localhost ~]# tar zxvf mysql-5.7.18.tar.gz -C /usr/src/
[root@localhost ~]# tar zxvf boost_1_59_0.tar.gz -C /mysql/
[root@localhost ~]# chown -R mysql.mysql /mysql/
[root@localhost ~]# chmod -R 755 /mysql/
[root@localhost ~]# chown -R mysql.mysql /usr/src/mysql-5.7.18/
5、开始编译安装MySQL5.7.18
[root@localhost ~]# su - mysql
[mysql@localhost ~]$ cd /usr/src/mysql-5.7.18/
[mysql@localhost mysql-5.7.18]$cmake . -DCMAKE_INSTALL_PREFIX=/mysql/mysql5718 \
-DMYSQL_DATADIR=/mysql/data \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=/mysql/boost_1_59_0
[mysql@localhost mysql-5.7.18]$ make -j 4 （并行4个进程同时进行编译）
[mysql@localhost mysql-5.7.18]$ make install
6、初始化数据库：
[mysql@localhost ~]$ /mysql/mysql5718/bin/mysqld --initialize --user=mysql --basedir=/mysql/mysql5718/ --datadir=/mysql/data/
---注意，在初始化数据库会生成数据库的默认密码，这个密码要记住，一会登录数据库要用
7、编辑my.cnf配置文件，启动数据库
[mysql@localhost ~]$ vim my.cnf （该配置文件仅供参考）

[mysql@localhost ~]$ /mysql/mysql5718/bin/mysqld_safe --defaults-file=/mysql/data/my.cnf --user=mysql &
8、进入数据库检查：
[mysql@localhost ~]$ /mysql/mysql5718/bin/mysql -u root -p --socket=/mysql/data/mysql.sock
Enter password:

mysql> set password='123456'; （因为刚才使用的密码是个默认的登录密码，所以我们要修改）
mysql> flush privileges;
然后重新登录数据库，进行检查：
[mysql@localhost ~]$ /mysql/mysql5718/bin/mysql -u root -p --socket=/mysql/data/mysql.sock
Enter password:
