基于通用二进制方式安装Mysql-5.7.24

之前安装mysql时候比较慢，以下是加速版的

上传安装包mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

1、确保系统中有依赖的libaio软件，使用如下命令

[root@localhost ~]# yum -y install libaio

[root@localhost ~]# rpm -q libaio
libaio-0.3.109-13.el7.x86_64

2、使用wget命令下载mysql-5.7.24软件包

3、将mysql安装包解压到指定目录，命令如下

[root@localhost ~]# tar xf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz -C /usr/local/    //估计用时有点慢

4、进入到/usr/local/目录

[root@localhost ~]# cd /usr/local/
[root@localhost local]# ls
bin
etc
games
include
lib
lib64
libexec
mysql-5.7.24-linux-glibc2.12-x86_64
nginx
sbin
share
src

5、为mysql安装目录创建软连接

[root@localhost local]# ln -s mysql-5.7.24-linux-glibc2.12-x86_64/ mysql

也可以用

[root@localhost local]# mv mysql-5.7.24-linux-glibc2.12-x86_64/ mysql

6、添加mysql用户和组

[root@localhost local]# useradd -M -s /sbin/nologin mysql

7、修改当前目录拥有者为新建的mysql用户，命令如下

[root@localhost local]# chown -R mysql:mysql /usr/local/mysql/

8、初始化mysql数据库（建立默认的库和表），命令如下

[root@localhost local]# cd /usr/local/mysql/

[root@localhost mysql]# /usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize

porary password is generated for root@localhost: hr%5qe:XrjiI   //记下随机产生的密码

9、修改mysql配置文件，命令如下

[root@localhost ~]# vim /etc/my.cnf

   2 datadir=/usr/local/mysql/data
  3 socket=/tmp/mysql.sock

12 log-error=/usr/local/mysql/data/mysql.log
 13 pid-file=/usr/local/mysql/data/mysql.pid

保存退出

10、将mysql服务添加到系统服务中，命令如下

[root@localhost ~]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

[root@localhost ~]# chmod +x /etc/init.d/mysqld
[root@localhost ~]# chkconfig --add mysqld

[root@localhost ~]# systemctl start mysqld

tcp6       0      0 :::3306                 :::*                    LISTEN      48952/mysqld

11、将mysql命令添加到系统命令执行路径中，便于使用

[root@localhost ~]# ln -s /usr/local/mysql/bin/mysql /bin/

12、使用随机密码登录mysql数据库，命令如下

[root@localhost ~]# mysql -uroot -p'hr%5qe:XrjiI'

。。。。。

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

mysql>

mysql> exit
Bye

13、设置mysql管理用户root的新密码

[root@localhost ~]# ln -sf /usr/local/mysql/bin/* /bin/
[root@localhost ~]# mysqladmin -uroot -p'hr%5qe:XrjiI' password 123456
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

[root@localhost ~]# mysql -uroot -p123456

破译密码：

在生产环境中，要保证在业务不繁忙的情况下进行破译，因为破译时需要进行关闭数据库

[root@localhost ~]# systemctl stop mysqld

[root@localhost ~]# ps aux |grep mysqld
root      49128  0.0  0.0 112676   984 pts/2    S+   21:43   0:00 grep --color=auto mysqld  //确保没有与之相关的进程

[root@localhost ~]# mysqld_safe --skip-grant-tables &
[1] 49145
[root@localhost ~]# 2019-11-20T13:44:53.569922Z mysqld_safe Logging to '/usr/local/mysql/data/mysql.log'.
2019-11-20T13:44:53.588675Z mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data           ///放到后台去启动

[root@localhost ~]# mysql            //可以不用密码进入
