引言
最近发现运维同时安装常用的软件非常的快，但是回想之前自己安装的时候 比较麻烦，每次都得查一些资料，所以决定弄一些安装教程，特此在记录，纯属记录，没有技术含量。
1、上传下载好的安装包到指定目录 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 2018-12-07T02:37:59.719825Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.
