CentOS6.9+Mysql5.7.18源码安装，以下操作均在root用户下执行。
1、安装依赖工具
cmake make3.75+ gcc4.4.6+ Boost1.59.0 bison ncurses
yum install -y cmake,make,gcc,gcc-c++,bison, ncurses,ncurses-devel
cd /opt
wgethttps://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
或者向度娘要一个
tar -zxvf boost_1_59_0.tar.gz -C /usr/local/
2、下载mysql准备安装
git clone https://github.com/mysql/mysql-server.git
没有git就 yum install git装一个
选择5.7
创建mysql用户，用户组为root
useradd -r -g root -s /bin/false mysql
3、执行cmake
cd /opt/mysql-server5.7
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_DATADIR=/usr/local/mysql/data
-DWITH_BOOST=/usr/local/boost_1_59_0
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock
-DSYSCONFDIR=/etc
-DEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci
-DENABLED_LOCAL_INFILE=1
-DEXTRA_CHARSETS=all
-DCMAKE_INSTALL_PREFIX：安装路径-DMYSQL_DATADIR：数据存放目录-DWITH_BOOST：boost源码路径-DSYSCONFDIR：my.cnf配置文件目录-DEFAULT_CHARSET：数据库默认字符编码-DDEFAULT_COLLATION：默认排序规则-DENABLED_LOCAL_INFILE：允许从本文件导入数据-DEXTRA_CHARSETS：安装所有字符集 4、编译安装
make -j `grep processor /proc/cpuinfo | wc -l`
make install
-j参数表示根据CPU核数指定编译时的线程数，可以加快编译速度。
如果中途编译失败了，需要删除cmake生成的预编译配置参数的缓存文件和make编译后生成的文件，再重新编译。
cd /opt/mysql-server5.7
rm -f CMakeCache.txt
make clean
5、初始化系统数据库
vim /etc/my.cnf
进入insert模式，将原来内容替换成如下内容： CentOS6.9+Mysql5.7.18源码安装教程

cd /usr/local/mysql
mkdir data
mkdir logs
mkdir temp
chmod 0770 -R .
./mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql --socket=/tmp/mysql.sock
在MySQL 5.7.6版本以前是 bin/mysql_install_db --user
执行完成后，查看 logs/mysql_error.log文件，将里面的临时root密码记下来
A temporary password is generated for root@localhost: xxxxxxxxxx
6、配置mysql
chkconfig --add mysqld # 添加到系统服务
chkconfig mysqld on # 开机启动
service mysqld start启动不成功，使用safe模式启动
chown -R mysql:root /var/run/mysqld
./bin/mysqld_safe --defaults-file=/etc/my.cnf --user=mysql &
./mysql -uroot -p
输入mysql_error.log中的临时密码登入mysql控制台
set password='asdfghjkl'';
Query OK, 0 rows affected (0.00 sec)
show warnings;
停止mysql
mysqladmin -u root -p shutdown
输入刚才设置的密码，停止成功
接下来可以使用系统服务来启动mysql了：
service mysqld start # 启动mysql服务
