1、下载文件(https://pan.baidu.com/s/1c1VBcHy)放到目录:/usr/local/
2、解压
cd /usr/local/ tar -zxvf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz.tar.gz
mkdir mysql mv mysql-5.7.20-linux-glibc2.12-x86_64/* mysql groupadd mysql //创建用户组mysql useradd -r -g mysql mysql //-r参数表示mysql用户是系统用户,不可用于登录系统,创建用户mysql并将其添加到用户组mysql中 chown -R mysql mysql/ chgrp -R mysql mysql/
3、创建配置文件
vim /etc/my.cnf
内容如下,可以添加你需要的配置:
[client] port = 3306 socket = /tmp/mysql.sock [mysqld] character_set_server=utf8 init_connect='SET NAMES utf8' basedir=/usr/local/mysql datadir=/usr/local/mysql/data socket=/tmp/mysql.sock log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
#不区分大小写
lower_case_table_names = 1
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
max_connections=5000
default-time_zone = '+8:00'
保存内容,按esc输入如下命令
:wq!
4、初始化数据库
#先安装一下这个东东,要不然初始化有可能会报错
yum install libaio
#手动编辑一下日志文件,什么也不用写,直接保存退出
cd /var/log/
vim mysqld.log
:wq
chmod 777 mysqld.log
chown mysql:mysql mysqld.log
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --lc_messages_dir=/usr/local/mysql/share --lc_messages=en_US
5、查看初始密码
cat /var/log/mysqld.log
执行后关注最后一点:root@localhost: 这里就是初始密码
6、启动服务,进入mysql,修改初始密码,运行远程连接(这里执行完后,密码将变成:123456)
cd /var/run/
mkdir mysqld
chmod 777 mysqld
cd mysqld
vim mysqld.pid
chmod 777 mysqld.pid
chown mysql:mysql mysqld.pid
/usr/local/mysql/support-files/mysql.server start /usr/local/mysql/bin/mysql -uroot -p你在上面看到的初始密码
// 以下是进入数据库之后的sql语句 use mysql; UPDATE `mysql`.`user` SET `Host`='%', `User`='root', `Select_priv`='Y', `Insert_priv`='Y', `Update_priv`='Y', `Delete_priv`='Y', `Create_priv`='Y', `Drop_priv`='Y', `Reload_priv`='Y', `Shutdown_priv`='Y', `Process_priv`='Y', `File_priv`='Y', `Grant_priv`='Y', `References_priv`='Y', `Index_priv`='Y', `Alter_priv`='Y', `Show_db_priv`='Y', `Super_priv`='Y', `Create_tmp_table_priv`='Y', `Lock_tables_priv`='Y', `Execute_priv`='Y', `Repl_slave_priv`='Y', `Repl_client_priv`='Y', `Create_view_priv`='Y', `Show_view_priv`='Y', `Create_routine_priv`='Y', `Alter_routine_priv`='Y', `Create_user_priv`='Y', `Event_priv`='Y', `Trigger_priv`='Y', `Create_tablespace_priv`='Y', `ssl_type`='', `ssl_cipher`='', `x509_issuer`='', `x509_subject`='', `max_questions`='0', `max_updates`='0', `max_connections`='0', `max_user_connections`='0', `plugin`='mysql_native_password', `authentication_string`='*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9', `password_expired`='N', `password_last_changed`='2017-11-20 12:41:07', `password_lifetime`=NULL, `account_locked`='N' WHERE (`User`='root');
flush privileges;
#如果提示必须要修改密码才可以进行操作的话则执行下面操作
set password=password('新密码');
flush privileges;
UPDATE `mysql`.`user` SET `Host` = '%', `User` = 'root' WHERE (`Host` = 'localhost') AND (`User` = 'root');
7、开机自启
cd /usr/local/mysql/support-files
cp mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
8、使用service mysqld命令启动/停止服务
例如我的mysql:启动/停止/暂停:
su - mysql
service mysqld start/stop/restart
