在我百撕不得其姐情况下,百度到了一篇亲测有用的文章,如下:

1.这里我将Mysql安装在/usr/local/mysql目录里面，也可以安装在其他地方;

mkdir /usr/local/mysql

2.下载MySQL压缩包

wget http://dev.MySQL.com/get/Downloads/MySQL-5.7/mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz // 如果上边的命令不行的话 可以使用下边的命令curl -O -L http://dev.MySQL.com/get/Downloads/MySQL-5.7/mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz 

3.解压并复制

tar -xvf mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gzmv mysql-5.7.11-linux-glibc2.5-x86_64/* /usr/local/mysql/

4.创建data目录

mkdir /usr/local/mysql/data

5.创建mysql用户组及其用户

groupadd mysqluseradd -r -g mysql mysql

6.初始化数据

[root@localhost mysql] ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/2016-01-20 02:47:35 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize2016-01-20 02:47:45 [WARNING] The bootstrap log isn‘t empty:2016-01-20 02:47:45 [WARNING] 2016-01-19T18:47:36.732678Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead2016-01-19T18:47:36.750527Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)2016-01-19T18:47:36.750560Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000

7.复制配置文件到 /etc/my.cnf

cp -a ./support-files/my-default.cnf /etc/my.cnf (选择y) 

8.MySQL的服务脚本放到系统服务中

cp -a ./support-files/mysql.server /etc/init.d/mysqld修改my.cnf文件# These are commonly set, remove the # and set as required.basedir = /usr/local/mysqldatadir = /usr/local/mysql/dataport = 3306# server_id = .....socket = /tmp/mysql.sockcharacter-set-server = utf8# Remove leading # to set options mainly useful for reporting servers.# The server defaults are faster for transactions and fast SELECTs.# Adjust sizes as needed, experiment to find the optimal values.# join_buffer_size = 128M# sort_buffer_size = 2M# read_rnd_buffer_size = 2M 

9.创建In

ln -s /usr/local/mysql/ /usr/bin/

10.启动服务

service mysqld start 

11.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。[root@localhost ~]# cat /root/.mysql_secret# Password set for user ‘root@localhost‘ at 2017-03-16 00:52:34 ws;fmT7yh0CM

12.登录并修改密码

[root@localhost ~]# mysql -u root -palter user root@localhost identified by ‘root‘;flush privileges;

13.退出重新登录，完成

mysql> show databases;+--------------------+| Database |+--------------------+| information_schema || mysql || performance_schema || sys |+--------------------+4 rows in set (0.11 sec)

ok了
