linux 用户状态安装mysql

下完安装包：
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz

用户目录下解压：
tar -zxvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz

创建文件夹
mkdir mysql
ln -s mysql-5.7.21-linux-glibc2.12-x86_64 mysql

通过vi新增mysql配置文件my.cnf
[client]
port=3336
socket=/home/wpt/package/mysql/mysql.sock
[mysqld]
port=3336
basedir=/home/wpt/package/mysql
datadir=/home/wpt/package/mysql/data
pid-file=/home/wpt/package/mysql/mysql.pid
socket=/home/wpt/package/mysql/mysql.sock
log_error=/home/wpt/package/mysql/error.log
server-id=100

安装mysql
$ bin/mysqld --defaults-file=/home/wpt/package/mysql/my.cnf --initialize --user=WPT --basedir=/home/wpt/package/mysql --datadir=/home/wpt/package/mysql/data

启动mysql：
bin/mysqld_safe --defaults-file=/home/wpt/package/mysql/my.cnf --user=WPT &
获取密码
cat error.log | grep root@localhost

登陆mysql：
bin/mysql -u root -p

不存在/tmp/mysql.sock，我们在my.cnf配置的mysql.sock路径是/home/wlf/mysql/mysql.sock，所以当mysql去找这个文件时，我们让它换个地方去找：
ln -s /home/wpt/package/mysql/mysql.sock /tmp/mysql.sock

更改密码
set password for ‘root’@‘localhost’ = password(‘123456’);
flush privileges;
