GDB调试Mysql实战之源码编译安装

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=<directory> -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<swtX.8og

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