linux6.5 RPM方式安裝 mysql5.6

步驟一、檢查下linux是不是已經安裝了MySQL

# rpm -qa|grep mysql
mysql-libs-5.1.71-1.el6.x86_64

# rpm -e --nodeps mysql-libs-5.1.71-1.el6.x86_64  //卸載

# find / -name mysql//有mysql文件夾的話，把mysql的文件夾刪掉

步驟二、下載需要的安裝包，下載地址：

https://dev.mysql.com/downloads/mysql/5.6.html#downloads

步驟三、將下載的文件進行解壓：

# tar -xvf MySQL-5.6.41-1.el6.x86_64.rpm-bundle.tar 
MySQL-client-5.6.41-1.el6.x86_64.rpm
MySQL-shared-compat-5.6.41-1.el6.x86_64.rpm
MySQL-test-5.6.41-1.el6.x86_64.rpm
MySQL-server-5.6.41-1.el6.x86_64.rpm
MySQL-devel-5.6.41-1.el6.x86_64.rpm
MySQL-shared-5.6.41-1.el6.x86_64.rpm
MySQL-embedded-5.6.41-1.el6.x86_64.rpm

步驟四、按順序依次安裝：

rpm -ivh MySQL-devel-5.6.41-1.el6.x86_64.rpm
rpm -ivh MySQL-server-5.6.41-1.el6.x86_64.rpm
rpm -ivh MySQL-client-5.6.41-1.el6.x86_64.rpm

沒有ERROR日志，說明安裝成功；

步驟五、啟動mysql

# service mysql start
Starting MySQL.Logging to '/var/lib/mysql/C5-3_SOA23.cnpc.com.cn.err'.
   [  OK  ]

步驟六、查看默認密碼

# cat /root/.mysql_secret 

步驟七、登錄

# mysql -u root -p

遇到的問題：

1、登錄時，報錯

# mysql -uroot -p
mysql: unknown variable 'sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES'

解決方式：

# vi /etc/my.cnf

把 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 這句話注釋掉；

2、要使用sql語句，必須重設password

mysql> use mysql
ERROR 1820 (HY000): You must SET PASSWORD before executing this statement

解決方式：

mysql> SET PASSWORD = PASSWORD('123456');//123456是新密碼

3、設置遠程登錄：

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
mysql> flush privileges;
