- 第一步：下載mysql最新版
wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
- 第二步：在/usr/local/中解壓壓縮包衣撬，并改名為mysql
cd /usr/local/
tar -xzvf /data/software/mysql-5.7.13-linux-glibc2.5-x86_64.tar.gz (我的下載目錄為 data/software)
mv mysql-5.7.13-linux-glibc2.5-x86_64 mysql
- 第三步：創(chuàng)建用戶組mysql渐扮，創(chuàng)建用戶mysql并將其添加到用戶組mysql中觉阅，并賦予讀寫權(quán)限
groupadd mysql
useradd -r -g mysql mysql
chown -R mysql mysql/
chgrp -R mysql mysql/
- 第四步：創(chuàng)建配置文件
vim /etc/my.cnf
#復(fù)制以下內(nèi)容
[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
#不區(qū)分大小寫
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'
按ESC保存并關(guān)閉缔恳，輸入如下命令
:wq!
- 第五步：初始化數(shù)據(jù)庫(kù)
#先安裝一下這個(gè)東東猪杭，要不然初始化有可能會(huì)報(bào)錯(cuò)
yum install libaio
#手動(dòng)編輯一下日志文件，什么也不用寫纠亚，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
- 第六步：查看初始密碼
cat /var/log/mysqld.log
執(zhí)行后關(guān)注最后一點(diǎn)：root@localhost: 這里就是初始密碼
- 第七步：?jiǎn)?dòng)服務(wù)塘慕，進(jìn)入mysql，修改初始密碼蒂胞，運(yùn)行遠(yuǎn)程連接（這里執(zhí)行完后图呢，密碼將變成：你設(shè)置的新密碼）
service mysqld start
#如果提示必須要修改密碼才可以進(jìn)行操作的話則執(zhí)行下面操作
MySQL版本5.7.6版本以前用戶可以使用如下命令：
mysql> SET PASSWORD = PASSWORD('Xiaoming250');
MySQL版本5.7.6版本開始的用戶可以使用如下命令：
mysql> ALTER USER USER() IDENTIFIED BY 'Xiaoming250';
flush privileges;
UPDATE `mysql`.`user` SET `Host` = '%', `User` = 'root' WHERE (`Host` = 'localhost') AND (`User` = 'root');
#然后執(zhí)行如下操作開啟mysql服務(wù)，以及設(shè)置相關(guān)權(quán)限
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碼
# 以下是進(jìn)入數(shù)據(jù)庫(kù)之后的sql語句
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;
- 第八步：開機(jī)自啟
cd /usr/local/mysql/support-files
cp mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
- 第九步：使用service mysqld命令啟動(dòng)/停止服務(wù)
su - mysql
service mysqld start/stop/restart
遠(yuǎn)程用戶建立
grant all privileges on *.* to '新用戶名'@'%' identified by '新密碼';
flush privileges;
添加系統(tǒng)路徑
vim /etc/profile
export PATH=/usr/local/mysql/bin:$PATH
source /etc/profile
