返回上層目錄中，初始化mysql
cd ../
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
如果報出權限不夠，可以在/usr/local/mysql目錄下手動新建一個data目錄 mkdir data
複製my_default.cnf和mysql.server文件到對應目錄
cp -a support-files/my_default.cnf /etc/my.cnf
cp -a support-files/mysql.server /etc/init.d/mysqld
啓動mysql
bin/mysqld_safe --user=mysql
或者將mysql的安裝路徑配置到系統路徑
vim /etc/profile
添加以下代碼
export PATH=/usr/local/mysql/bin:$PATH
source /etc/profile刷新
啓動mysql
service mysqld start
進入mysql客戶端
mysql -u root -p
輸入初始化時出現的密碼
若在這過程中有mysqld.sock錯誤，很大可能是my.cnf中socket配置的路徑不存在或者權限不夠，這時候手動創建該路徑並分配權限即可
mkdir /var/run/mysqld
chmod -R 777 /var/run/mysqld
