下载源码

git clone https://github.com/mysql/mysql-server.git cd mysql-server git checkout 5.7

编译安装

安装依赖

yum install -y cmake make gcc gcc-c++ ncurses-devel bison gdb

需要注意的一点，需要指定 boost 路径，会 cmake 的时候自动下载

cd BUILD; cmake .. -DDOWNLOAD_BOOST=1 -DWITH_BOOST= -DWITH_DEBUG=1 -DWITH_UNIT_TESTS=off make make install

最后程序安装到了/usr/local/mysql目录

创建专用用户

groupadd mysql useradd -s /sbin/nologin -M -g mysql mysql

初始化数据库

cd /usr/local/mysql/ bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql 2019-02-01T07:45:58.147032Z 1 [Note] A temporary password is generated for root@localhost: jss

连接数据库

[root@bogon bin]# ./mysql -h localhost -uroot ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

原来是因为配置文件里面没有置顶客户端的 socket 文件

cat /etc/my.cnf [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock

  1. Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0
  2. Settings user and group are ignored when systemd is used.
  3. If you need to run mysqld under a different user or group,
  4. customize your systemd unit file for mariadb according to the
  5. instructions in http://fedoraproject.org/wiki/Systemd [mysqld_safe] log-error=/var/log/mariadb/mariadb.log pid-file=/var/run/mariadb/mariadb.pid
    1. include all files from the config directory
  7. !includedir /etc/my.cnf.d

增加

[client] default-character-set=utf8 socket=/var/lib/mysql/mysql.sock [mysql] default-character-set=utf8 socket=/var/lib/mysql/mysql.sock

再次连接就 ok 了。

修改默认密码

SET PASSWORD = PASSWORD('123456'); ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER; flush privileges;

导入测试数据

/usr/local/mysql/bin/mysql -uroot -p123456 test < article_rank.sql
