mysql-5.7.34编译安装

1、下载并解压到：/Users/xiechunping/Softwares/mysql-5.7.34
下载地址：http://ftp.ntu.edu.tw/pub/MySQL/Downloads/MySQL-5.7/mysql-boost-5.7.34.tar.gz

2、进入mysql-5.7.34，执行cmake
cd ../mysql-5.7.34
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1-DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_USER=_mysql -DMYSQL_TCP_PORT=3306 -DMYSQL_DATADIR=/usr/local/mysql/db_data -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/Users/xiechunping/Softwares/mysql-5.7.34/boost

3、配置数据目录权限
chown -R _mysql:_mysql /usr/local/mysql/db_data

4、make&&make install

5、安装数据库并启动
cd /usr/local/mysql
bin/mysql_install_db --user=mysql --datadir=/usr/local/mysql/db_data
support-files/mysql.server start

6、修改数据库root用户密码（首次进入密码为空）
修改：/usr/local/mysql/support-files/mysql.server第280行
为mysql的启动选项增加：--user=mysql --skip-grant-tables --skip-networking
执行：
support-files/mysql.server stop && support-files/mysql.server stop
bin/mysql -u root mysql
mysql>UPDATE user SET authentication_string=PASSWORD('123456789') where USER='root';
mysql>FLUSH PRIVILEGES;
mysql>quit;

support-files/mysql.server stop
还原/usr/local/mysql/support-files/mysql.server文件
support-files/mysql.server start

/usr/bin/mysql -uroot -p
Enter password: <输入新设的密码123456789>
mysql>SET PASSWORD = PASSWORD('123456789');
mysql>ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
mysql>flush privileges;
mysql>quit;
