    下载地址:https://downloads.mysql.com/archives/community/

    [root@localhost soft]# ls
    mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz nginx-1.12.2 nginx-1.12.2.tar.gz
    [root@localhost soft]#
    

      

    1.详细描安装的过程

    1.1关闭防火墙

    systemctl stop firewalld.service #停止firewall
    systemctl disable firewalld.service #禁止firewall开机启动
    firewall-cmd --state #查看默认防火墙状态(关闭后显示notrunning,开启后显示running)
    

      

    检查是否安装NySQL,如果安装 卸载之

    rpm -qa |grep mysql

    yum remove mysql*

    检查是否安装MariaDB,如果安装 卸载之(重要)

    rpm -qa |grep mariadb

    yum remove mariadb*

     新增用户/组 参数文件

    groupadd mysql

    useradd mysql -g mysql -M -s /sbin/nologin

    创建目录并授权

    mkdir -p /data/3306 

    mkdir log

    chown -R mysql.mysql /data

    配置文件和启动文件修改:

     mv ./my.cnf /etc/

     cp /application/mysql/support-files/mysql.server  /etc/init.d/mysqld

    vim /etc/init.d/mysqld

    修改:

    basedir=/application/mysql
    datadir=/data/3306/data

    初始化:

     ./bin/mysqld  --initialize --user=mysql --basedir=/application/mysql --datadir=/data/3306/data

    [root@localhost 3306]# grep 'temporary password' ./mysql_error.log 
    2018-08-05T15:30:45.859098Z 1 [Note] A temporary password is generated for root@localhost: r6IiVQkl_mfm
    r6IiVQkl_mfm为mysql的root用户登录的随机密码

    启动mysql
    [root@localhost 3306]# service mysqld start
    Starting MySQL.2018-08-05T15:35:41.111817Z mysqld_safe The file /usr/local/mysql/bin/mysqld
    does not exist or is not executable. Please cd to the mysql installation
    directory and restart this script from there as follows:
    ./bin/mysqld_safe&
    See http://dev.mysql.com/doc/mysql/en/mysqld-safe.html for more information
     ERROR! The server quit without updating PID file (/data/3306/data/localhost.localdomain.pid).
    [root@localhost 3306]# 
    

      

    会发现报错了。。。。。。。。不要慌

    错误:/usr/local/mysql/bin/mysqld does not exist 

    解决:

    [root@localhost 3306]# mkdir -p /usr/local/mysql/bin
    [root@localhost 3306]# ln -s /application/mysql/bin/mysqld  /usr/local/mysql/bin
    

      

    大功告成了:

    [root@localhost 3306]# service mysqld start                                     
    Starting MySQL.. SUCCESS! 
    

      

    把mysql命令加到环境变量中

    vim /etc/profile
    最底下修改:
    PATH="/application/mysql/bin/:$PATH"
    tail -1  /etc/profile
    source /etc/profile
    [root@localhost 3306]# ps -ef|grep mysqld
    root      3822     1  0 23:38 pts/2    00:00:00 /bin/sh /application/mysql/bin/mysqld_safe --datadir=/data/3306/data --pid-file=/data/3306/data/localhost.localdomain.pid
    mysql     4275  3822  0 23:38 pts/2    00:00:00 /usr/local/mysql/bin/mysqld --basedir=/application/mysql --datadir=/data/3306/data --plugin-dir=/application/mysql/lib/plugin --user=mysql --log-error=/data/3306/mysql_error.log --open-files-limit=65535 --pid-file=/data/3306/data/localhost.localdomain.pid --socket=/data/3306/mysql.sock --port=3306
    root      4378  2807  0 23:42 pts/2    00:00:00 grep --color=auto mysqld

    登录mysql: 密码为上面随机密码

    mysql -uroot -pr6IiVQkl_mfm

    登录成功之后再修改密码:

    mysql> set PASSWORD=PASSWORD('123456');
    Query OK, 0 rows affected, 1 warning (0.00 sec)

    flush privileges;

      

    mysql> show databases;

    mysql远程链接:

    mysql> use mysql;
    Database changed
    mysql> update user set host ='%'where user ='root' and host ='localhost';
    Query OK, 1 row affected (0.00 sec)
    Rows matched: 1  Changed: 1  Warnings: 0
