使用yum安装mysql

[root@vm10-0-0-3 ~]# yum install mysql* -y

卸载mysql

[root@vm10-0-0-3 ~]# yum list install mysql*| awk '{print $1}' | xargs rpm -e --nodeps

下载mysql安装包

点击下载，拿到下载连接https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz

[root@vm10-0-0-3 local]# wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz

解包

[root@vm10-0-0-3 local]# tar -zxvf mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz

重命名

[root@vm10-0-0-3 local]# mv mysql-5.7.29-linux-glibc2.12-x86_64 mysql

创建data目录

[root@vm10-0-0-3 mysql]# mkdir data

新建mysql用户及用户组

[root@vm10-0-0-3 mysql]# useradd mysql
[root@vm10-0-0-3 mysql]# passwd mysql

修改目录权限

[root@vm10-0-0-3 local]# chown -R mysql:mysql mysql

编译运行初始化

[root@vm10-0-0-3 bin]# ./mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql

执行报错

./mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

安装报错类库

[root@vm10-0-0-3 bin]# yum install libaio.so.1
[root@vm10-0-0-3 bin]# yum -y install numactl

重新执行还是同样的报错

[root@vm10-0-0-3 bin]# ./mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql
./mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
