详解Mac系统下源码编译安装MySQL5.7.17的教程

1、下载并解压到：/Users/xiechunping/Softwares/mysql-5.7.17

2、进入mysql-5.7.17，执行cmake

cd ../mysql-5.7.17
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-5.7.17/boost

3、配置数据目录权限

chown -R _mysql:_mysql /usr/local/mysql/db_data

4、编译并安装

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('mysql54321') 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

bin/mysql -uroot -p
Enter password: <输入新设的密码mysql54321>
mysql>SET PASSWORD = PASSWORD('mysql54321');
mysql>ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
mysql>flush privileges;
mysql>quit;
