**3. 上传下载好的包，解压缩，创建mysql安装目录，并给予权限.**

[root@localhost ~]# ls
    mysql-5.7.32-linux-glibc2.12-x86_64.tar.gz
    [root@localhost ~]# tar zxf mysql-5.7.32-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
    [root@localhost ~]# mv /usr/local/mysql-5.7.32-linux-glibc2.12-x86_64/ /usr/local/mysql
    [root@localhost ~]# mkdir /usr/local/mysql/data
    [root@localhost ~]# chown -R mysql.mysql /usr/local/mysql/
    [root@localhost ~]# ll /usr/local/mysql/
    总用量 260

    -rw-r--r--  1 mysql mysql 247914 9月  23 20:00 LICENSE
    drwxr-xr-x  4 mysql mysql     30 12月 27 15:04 man
    -rw-r--r--  1 mysql mysql    587 9月  23 20:00 README

    drwxr-xr-x  2 mysql mysql     90 12月 27 15:04 support-files

**4. 初始化mysql**

[root@localhost ~]# cd /usr/local/mysql/
    [root@localhost mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
    #初始化用户和安装位置和数据存放位置

**5. 到etc下配置mysql的配置文件**

vim /etc/my.cnf    ---将文件中所有内容注释掉在添加如下内容
    
    [root@youxi1 mysql]# vim /etc/my.cnf
    [mysqld]
    basedir=/usr/local/mysql
    datadir=/usr/local/mysql/data
    port=3306
    socket=/usr/local/mysql/mysql.sock
    character-set-server=utf8
    log-error=/var/log/mysqld.log
    pid-file=/tmp/mysqld.pid
    [mysql]
    socket=/usr/local/mysql/mysql.sock
    [client]
    socket=/usr/local/mysql/mysql.sock

**6. 配置环境变量，方便管理**

vim /etc/profile.d/mysql.sh
    最后一行加上这个
    export PATH=/usr/local/mysql/bin:$PATH
    保存刷新
    source /etc/profile.d/mysql.sh

1.  添加启动脚本 ，并修改密码

cp support-files/mysql.server /etc/init.d/mysqld
    
    chmod +x /etc/init.d/mysqld
    
    vim /etc/init.d/mysqld
    basedir=/usr/local/mysql　　  #第46行 补全安装目录
    datadir=/usr/local/mysql/data  #第47行 补全数据所在目录
    
    /etc/init.d/mysqld start      #刷新
    
    mysqladmin -u root -p'初始密码'  password '新密码'  #新密码必须包含大小写英文、数字、特殊符号。
    
    #登陆mysql
    mysq -uroot -p'新密码'
