引言
最近發現運維同時安裝常用的軟件非常的快，但是回想之前自己安裝的時候 比較麻煩，每次都得查一些資料，所以決定弄一些安裝教程，特此在記錄，純屬記錄，沒有技術含量。
1、上傳下載好的安裝包到指定目錄
2、yum install libaio libaio-devel
3、yum -y install numactl
4、tar zxvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz
5、mv mysql-5.7.21-linux-glibc2.12-x86_64 /usr/local/mysql57
6、groupadd mysql
7、useradd -r -g mysql mysql
8、[root@iZ25fpoaflxZ mysql57]# id mysql
uid=501(mysql) gid=502(mysql) groups=502(mysql)
9、[root@iZ25fpoaflxZ mysql57]# mkdir -p /data/mysql3306/data/
10、[root@iZ25fpoaflxZ mysql57]# chown -R mysql.mysql /data/mysql3306
11、[root@iZ25fpoaflxZ mysql57]# chmod 750 /data/mysql3306/data
12、[root@iZ25fpoaflxZ mysql57]# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql57 --datadir=/data/mysql3306/data
