摘要：下载源码编译安装安装依赖需要注意的一点，需要指定路径，会的时候自动下载最后程序安装到了目录创建专用用户初始化数据库连接数据库原来是因为配置文件里面没有置顶客户端的文件增加再次连接就了。修改默认密码导入测试数据
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
