1. 系統信息
   CentOS release 6.5 (Final)
   2.6.32-431.el6.x86_64
2. 目錄創建
   程序目錄：/usr/local/mysql_5.7.22/
   數據目錄：/var/lib/mysql_5.7.22/data/
   命令：

   mkdir /var/lib/mysql_5.7.22/{data,logs,tmp} -p
   chown -R mysql:mysql  /var/lib/mysql_5.7.22

3. 安裝依賴
   yum -y install numactl.x86_64
   不然初始化報錯：
   error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory
4. 準備my.cnf配置文件
   參數詳細解釋參考：https://blog.csdn.net/gzt19881123/article/details/52594783

   二. 安裝初始化

5. 下載解壓：
   https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

   tar -xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
   mv mysql-5.7.22-linux-glibc2.12-x86_64/  mysql_5.7.22

6. 初始化：
   /usr/local/mysql_5.7.22/bin/mysqld --defaults-file=/usr/local/mysql_5.7.22/my.cnf --basedir=/usr/local/mysql_5.7.22/ --datadir=/var/lib/mysql_5.7.22/data/ --initialize
   
   查看日誌less /var/lib/mysql_5.7.22/logs/error.log，看是否有報錯
7. 啟動mysql
   /usr/local/mysql_5.7.22/bin/mysqld_safe --defaults-file=/usr/local/mysql_5.7.22/my.cnf &
   這個時候會報錯顯示沒有/var/lib/mysql_5.7.22/logs/mysqld.log這個日誌文件，手動創建，重新啟動就不會報錯
   touch /var/lib/mysql_5.7.22/logs/mysqld.log
   啟動完成後，查看日誌文件是否有報錯
   ps waux |grep mysql 查看進程是否啟動
8. 登錄mysql
   grep password /var/lib/mysql_5.7.22/logs/error.log 查看原始密碼
   類似這樣root@localhost: yn.X?gQ!d2?3
   /usr/local/mysql_5.7.22/bin/mysql -uroot -p‘yn.X?gQ!d2?3‘ -S /var/lib/mysql_5.7.22/tmp/mysql.sock
9. 登錄mysql 後修改密碼
   set password=password(‘123456’);

二進制安裝mysql 5.7.22
