一、下载mysql8.0安装包
1、在local创建mysql文件夹
cd /usr/local mkdir mysql cd mysql
2、使用wget下载mysql8.0的xz安装包
二、解压mysql8.0安装包
1、解压
2、重命名解压后的mysql文件夹(名字太长了)
3、创建data存储文件
cd mysql8.0 mkdir data
三、创建用户和用户组,并赋予权限
1、创建用户和用户组
groupadd mysql useradd -g mysql mysql
2、给用户赋予权限
四、初始化mysql信息
1、切换到mysql8.0安装路径下
2、初始化mysql基本信息
3、获取到临时mysql密码
五、添加mysqld服务到系统
1、将mysqld服务添加到系统中
cd /usr/local/mysql/mysql8.0 cp -a ./support-files/mysql.server /etc/init.d/mysql
2、授权以及添加服务
chmod +x /etc/init.d/mysql chkconfig --add mysql
3、mysql5.7以后就没有my.cnf了,所以我们创建一个。(个人觉得方便一些)
# Example MySQL config file for small systems. # # This is for a system with little memory (<= 64M) where MySQL is only used # from time to time and it's important that the mysqld daemon # doesn't use much resources. # # MySQL programs look for option files in a set of # locations which depend on the deployment platform. # You can copy this option file to one of those # locations. For information about these locations, see: # http://dev.mysql.com/doc/mysql/en/option-files.html # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] default-character-set=utf8 #password = k0Ui&wV(Z3yt port = 3306 socket = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] #配置mysql的文件夹 和 mysql data目录 basedir=/usr/local/mysql/mysql8.0 datadir=/usr/local/mysql/mysql8.0/data default-storage-engine=INNODB character-set-server=utf8 collation-server=utf8_general_ci port = 3306 socket = /tmp/mysql.sock skip-external-locking key_buffer_size = 16K max_allowed_packet = 1M table_open_cache = 4 sort_buffer_size = 64K read_buffer_size = 256K read_rnd_buffer_size = 256K net_buffer_length = 2K thread_stack = 128K # Don't listen on a TCP/IP port at all. This can be a security enhancement, # if all processes that need to connect to mysqld run on the same host. # All interaction with mysqld must be made via Unix sockets or named pipes. # Note that using this option without enabling named pipes on Windows # (using the "enable-named-pipe" option) will render mysqld useless! # #skip-networking server-id = 1 # Uncomment the following if you want to log updates #log-bin=mysql-bin # binary logging format - mixed recommended #binlog_format=mixed # Causes updates to non-transactional engines using statement format to be # written directly to binary log.

4、启动mysql服务
5、查看mysql服务状态
6、将mysql命令添加到服务
六、登录mysql
1、登录 密码使用之前随机生成的密码
2、修改管理员密码 其中123456是新的密码自己设置
3、重新加载缓存,使密码生效
4、退出mysql,用新密码尝试登录管理员
七、修改mysql配置,使其可以用工具远程登录
云服务器不能远程连接mysql,解决
