1.下载安装包
wget http://dev.MySQL.com/get/Downloads/MySQL-5.7/mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz
2.新建目录
mkdir /usr/local/mysql
mkdir /usr/local/mysql/data
3.解压安装包并复制
tar -xvf mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.11-linux-glibc2.5-x86_64/* /usr/local/mysql/
4.创建mysql用户及用户组
groupadd mysql
useradd -r -g mysql mysql
5.进入/usr/local/mysql/目录并初始化数据
./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/
6.修改/etc/my.cnf配置文件为如下
[mysqld]
#datadir=/var/lib/mysql
#主要配置
basedir = /usr/local/mysqldatadir = /usr/local/mysql/data
port = 3306
socket=/tmp/mysql.sock
character-set-server = utf8
#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]
#注释
#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
7.创建软链接
8.启动Mysql服务
service mysqld start
8.初始化密码
mysql5.7会生成一个初始化密码，在root中.mysql_secret文件中。
cat /root/.mysql_secret
9.登录并且修改密码
mysql -u root -p
alter user root@localhost identified by 'root';
flush privileges;
10.退出重新登录
