centos 7 安裝二進位制mysql 詳細步驟
1 下載地址：https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz 複製這個連結在迅雷上下載比較快。
2 上傳到centos伺服器：scp mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz [email protected]:/usr/local
3 解壓到 /usr/loacl 目錄
4 重新命名 mv mysql-5.7.24-linux-glibc2.12-x86_64 mysql
5 建立 mysql使用者和組
groupadd mysql
useradd mysql -g mysql
6 進入mysql目錄 建立data資料夾 mkdir data
7 修改mysql目錄的使用者許可權 chown -R mysql.mysql
8 進入mysql/bin 目錄 執行 ./mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ 初始化mysql
如果報 ./mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory 這個錯誤，說明沒有安裝libaio 那麼應該去安裝libaio
rpm -qa|grep libaio 檢查是否安裝若未安裝則執行：yum install libaio-devel.x86_64 安裝。安裝成功後進入mysql/bin目錄再次執行
./mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/
出現以下內容，說明初始化成功。@loaclhost 後面是初始化的登陸密碼。

9 新增mysql啟動到本地服務 cp /usr/local/mysql/mysql.server /etc/init.d/mysql.server
10 啟動mysql服務：service mysql.server start
看到
Starting MySQL.Logging to '/usr/local/mysql/data/iZ2ze2h6biv9bg5169c9gtZ.err'. [ OK ]
就表示啟動成功了。
11 設定環境變數，並使環境變數生效
export PATH=$PATH:/usr/local/mysql/bin
12 啟動mysql ，密碼是初始化使生成的預設密碼。到此，完全完成myql的安裝。
mysql -uroot -p
