wget
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/
# 重新命名
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使用者、mysql使用者組
# mysql使用者組
groupadd mysql
# mysql使用者
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/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data
# 如果出現以下錯誤:
2018-07-14 06:40:32 [warning] mysql_install_db is deprecated. please consider switching to mysqld --initialize# 則使用以下命令:2018-07-14 06:40:32 [error] child process: /usr/local/mysql/bin/mysqldterminated prematurely with errno= 32
2018-07-14 06:40:32 [error] failed to execute /usr/local/mysql/bin/mysqld --bootstrap --datadir=/usr/local/mysql/data --lc-messages-dir=/usr/local/mysql/share --lc-messages=en_us --basedir=/usr/local/mysql
-- server log begin --
-- server log end --
/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize# 如果出現以下錯誤:
/usr/local/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: no such file or directory# 則執行以下命令:
yum -y install numactl
# 完成後繼續安裝:
/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize
[mysqld]7、開啟服務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
# 將mysql加入服務
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、設定密碼
# 登入(由於/etc/my.cnf中設定了取消密碼驗證,所以此處密碼任意)
/usr/local/mysql/bin/mysql -u root -p
# 操作mysql資料庫
>>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、登入再次設定密碼(不知道為啥如果不再次設定密碼就操作不了資料庫了)
/usr/local/mysql/bin/mysql -u root -p
>>alter user 'root'@'localhost' identified by '修改後的密碼';
>>exit;
11、允許遠端連線
/usr/local/mysql/bin/mysql -u root -p
>>use mysql;
>>update user set host='%' where user = 'root';
>>flush privileges;
>>eixt;
12、新增快捷方式
ln -s /usr/local/mysql/bin/mysql /usr/bin
