简介 GDB调试Mysql实战之源码编译安装_Mysql_
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 # 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
