在linux上安装mysql（二进制，binary）

1. 去https://dev.mysql.com/downloads/file/?id=514030 下载mysql-5.7.40-linux-glibc2.12-x86_64.tar，将它scp到目标机器上。保存到/root/tools/下；

2. 执行如下命令，将这个tarball解压成两个文件：

tar -xf mysql-5.7.40-linux-glibc2.12-x86_64.tar

其中一个文件是mysql-5.7.40-linux-glibc2.12-x86_64.tar.gz，另一个文件是mysql-test-5.7.40-linux-glibc2.12-x86_64.tar.gz；

3. 将mysql-5.7.40-linux-glibc2.12-x86_64.tar.gz解压到当前文件夹：

tar -zxvf mysql-5.7.40-linux-glibc2.12-x86_64.tar.gz

这样，mysql就解压到/root/tools/mysql-5.7.40-linux-glibc2.12-x86_64 下了；

4. 将mysql/bin目录配置到path下：

vi /etc/profile

...


export MYSQL_HOME=/root/tools/mysql-5.7.40-linux-glibc2.12-x86_64
export PATH=$MYSQL_HOME/bin:$JAVA_HOME/bin:$PATH

...


source /etc/profile

5. 执行mysqld --initialize:

[root@localhost ~]# mysqld --initialize
