环境说明:
1. 系统环境: CentOS7-64位内存:4GB 硬盘:20GB (VMWARE虚拟机)

2. MySQL版本: 5.7.19

--------------

1. 下载MySQL

下载MySQL5.7.19源码包

下载后上传至Linux服务器，这里把源码包放到/usr/local目录下。

2. 环境准备

2.1 安装编译需要用到的依赖软件

如果数据库使用多实例，还需要安装: libaio, libaio-devel, 另外，还可安装: bison-devel openssl-devel。

(cmake加参数:-DWITH_SSL=yes时依赖openssl库)

2.2 添加mysql用户和用户组

执行命令: sudo groupadd mysql && sudo useradd mysql -s /sbin/nologin -M -g mysql

3. 开始安装

3.1 预编译

执行命令:

cd /usr/local/mysql-5.7.19 && sudo cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DMYSQL_UNIX_ADDR=/usr/local/mysql/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii -DENABLE_LOCAL_INFILE=ON -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITHOUT_PARTITION_STORAGE_ENGINE=1 -DWITH_FAST_MUTEXES=1 -DWITH_ZLIB=bundled -DENABLE_LOCAL_INFILE=1 -DWITH_READLINE=1 -DWITH_EMBEDDED_SERVER=1 -DWITH_DEBUG=0

出现如下错误，提示找不到boost库:

这里再添加两个参数: -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>, boost路径填/usr/local/boost即可，它会在这个目录找，找不到就会自己下载到该目录下，如下所示:

注意:
cmake生成的临时文件是CMakeCache.txt，重新cmake时，最好删除上一个CMakeCache.txt文件，避免不必要的错误。

3.2 编译

执行命令: sudo make 即可，注意，内存最好大于等于4G, 内存为2G可能会编译失败。编译完如下:

3.3 安装

执行命令: sudo make install。安装完如下:

3.4 配置

3.4.1 目录授权

另外，还需创建一个目录，命令: sudo mkdir /usr/local/mysql/tmp

3.4.2 初始化mysql的系统数据表

命令： sudo /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data

在Mysql5.7之前，初始化一般都是使用sripts目录下的mysql_install_db脚本，这里改为用mysqld了, 并且初始化后有一个默认的root随机密码:

3.4.3 创建配置文件

这里没有my-default.cnf文件:

我们在网站找一个，然后按我们的参数修改配置即可，命令:
sudo mv /etc/my.cnf /etc/my.cnf.bak && sudo mv my.cnf /etc/my.cnf，文件内容如下:

# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
[client]
#password	= your_password
port		= 3298
socket		= /usr/local/mysql/tmp/mysql.sock

# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (using the "enable-named-pipe" option) will render mysqld useless!
