下载源码
git clone https://github.com/mysql/mysql-server.git
cd mysql-server
git ch...
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
