1、下載tar包，這里使用wget從官網(wǎng)下載
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
2、將mysql安裝到/usr/local/mysql下
解壓
tar -xvf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
移動
mv mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/
重命名
mv /usr/local/mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/mysql
3、新建data目錄
mkdir /usr/local/mysql/data
4、新建mysql用戶、mysql用戶組
mysql用戶組
groupadd mysql
mysql用戶
useradd mysql -g mysql
5、將/usr/local/mysql的所有者及所屬組改為mysql
chown -R mysql.mysql /usr/local/mysql
6、配置
/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize
如果出現(xiàn)以下錯誤：
/usr/local/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory
則執(zhí)行以下命令：
yum -y install numactl
完成后繼續(xù)安裝：
/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize
編輯/etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
socket=/tmp/mysql.sock
user=mysql
port=3306
character-set-server=utf8
# 取消密碼驗證
skip-grant-tables
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# skip-grant-tables
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
7、開啟服務(wù)
將mysql加入服務(wù)
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
開機自啟
chkconfig mysql on
開啟
service mysql start
8、設(shè)置密碼
登錄（由于/etc/my.cnf中設(shè)置了取消密碼驗證，所以此處密碼任意）
/usr/local/mysql/bin/mysql -u root -p
操作mysql數(shù)據(jù)庫
use mysql;
修改密碼
update user set authentication_string=password('你的密碼') where user='root';
flush privileges;
exit;
9、將/etc/my.cnf中的skip-grant-tables刪除
10、登錄再次設(shè)置密碼（不知道為啥如果不再次設(shè)置密碼就操作不了數(shù)據(jù)庫了）
/usr/local/mysql/bin/mysql -u root -p
ALTER USER 'root'@'localhost' IDENTIFIED BY '修改后的密碼';
exit;
11、允許遠程連接
/usr/local/mysql/bin/mysql -u root -p
use mysql;
GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;
eixt;
12、添加快捷方式
ln -s /usr/local/mysql/bin/mysql /usr/bin
