关于MySQL的介绍我这里就不多做赘述了，如何下载MySQL详情请参考：MySQL入门介绍（mysql-8.0.13）。本篇博客默认你已经将MySQL二进制tar包下载好并上传到服务器上了。
一.使用默认的安装路径部署MySQL服务
1>.安装上传工具
[root@node101 ~]# yum -y install lrzsz
2>.上传MySQL的二进制安装包到服务器上
[root@node101 ~]# cd /usr/local/ [root@node101 local]# [root@node101 local]# ls bin etc games include lib lib64 libexec sbin share src [root@node101 local]# [root@node101 local]# rz rz waiting to receive. 开始 zmodem 传输。 按 Ctrl+C 取消。 100% 384621 KB 5827 KB/s 00:01:06 0 Errorss.xz... [root@node101 local]# [root@node101 local]# ls bin etc games include lib lib64 libexec mysql-8.0.13-linux-glibc2.12-x86_64.tar.xz sbin share src [root@node101 local]#
3>.在“/usr/local"目录进行解压操作并创建符号链接

二.迁移MySQL的安装目录
1>.迁移服务前，需要先关闭MySQL服务
[root@node101 ~]# /etc/init.d/mysql.server status SUCCESS! MySQL running (3058) [root@node101 ~]# [root@node101 ~]# [root@node101 ~]# /etc/init.d/mysql.server stop Shutting down MySQL... SUCCESS! [root@node101 ~]# [root@node101 ~]# [root@node101 ~]# /etc/init.d/mysql.server status ERROR! MySQL is not running [root@node101 ~]#
2>.将MySQL的数据目录迁移到指定的路径
[root@node101 ~]# mkdir -pv /yinzhengjie/data [root@node101 ~]# [root@node101 ~]# ll /yinzhengjie/data/ total 0 [root@node101 ~]# [root@node101 ~]# [root@node101 ~]# ll /usr/local/ total 384624 drwxr-xr-x. 2 root root 6 Aug 12 2015 bin drwxr-xr-x. 2 root root 6 Aug 12 2015 etc drwxr-xr-x. 2 root root 6 Aug 12 2015 games drwxr-xr-x. 2 root root 6 Aug 12 2015 include drwxr-xr-x. 2 root root 6 Aug 12 2015 lib drwxr-xr-x. 2 root root 6 Aug 12 2015 lib64 drwxr-xr-x. 2 root root 6 Aug 12 2015 libexec -rw-r--r--. 1 root root 393852364 Jan 15 05:10 mysql-8.0.13-linux-glibc2.12-x86_64 drwxr-xr-x. 2 root root 6 Aug 12 2015 sbin drwxr-xr-x. 5 root root 46 Jan 15 05:59 share drwxr-xr-x. 2 root root 6 Aug 12 2015 src [root@node101 ~]# [root@node101 ~]# mv /usr/local/mysql-8.0.13-linux-glibc2.12-x86_64 /yinzhengjie/data/mysql #停止服务后，我们将MySQL的数据目录移动到我们想要修改的指定位置 [root@node101 ~]# [root@node101 ~]# ll /yinzhengjie/data/ total 4 drwxr-xr-x. 10 mysql mysql 4096 Jan 15 16:04 mysql [root@node101 ~]#
3>.编辑MySQL的配置文件（由于我们移动了MySQL的安装目录以及数据目录，因此默认的配置已经不生效了，需要手动指定！）
[root@node101 ~]# [root@node101 ~]# cat /etc/my.cnf [mysqld] basedir=/yinzhengjie/data/mysql/ #指定MySQL的安装目录 datadir=/yinzhengjie/data/mysql/data #指定MySQL存放数据的目录 [root@node101 ~]#
4>.启动MySQL服务
[root@node101 ~]# /etc/init.d/mysql.server start Starting MySQL. SUCCESS! [root@node101 ~]#
三.安装MySQL是指定安装目录
1>.解压MySQL软件包到指定位置（指定你需要安装MySQL的路径，可以不是默认的"/usr/local"目录）
[root@node101 local]# mkdir -pv /yinzhengjie/softwares #创建存放MySQL的目录位置 mkdir: created directory ‘/yinzhengjie’ mkdir: created directory ‘/yinzhengjie/softwares’ [root@node101 local]# [root@node101 local]# ll /yinzhengjie/softwares/ total 0 [root@node101 local]# [root@node101 local]# tar -xf mysql-8.0.13-linux-glibc2.12-x86_64.tar.xz -C /yinzhengjie/softwares/ #创建MySQL的软件包 [root@node101 local]# [root@node101 local]# ll /yinzhengjie/softwares/ total 4 drwxr-xr-x. 9 root root 4096 Jan 16 05:48 mysql-8.0.13-linux-glibc2.12-x86_64 [root@node101 local]#
2>.将解压后的安装目录指定给mysql用户
[root@node101 ~]# chown mysql:mysql -R /yinzhengjie/softwares/mysql-8.0.13-linux-glibc2.12-x86_64/ [root@node101 ~]# [root@node101 ~]# ll /yinzhengjie/softwares/ total 4 drwxr-xr-x. 9 mysql mysql 4096 Jan 16 05:48 mysql-8.0.13-linux-glibc2.12-x86_64 [root@node101 ~]# [root@node101 ~]#
3>.配置MySQL的环境变量
[root@node101 ~]# ll /yinzhengjie/softwares/ total 4 drwxr-xr-x. 9 mysql mysql 4096 Jan 16 05:48 mysql-8.0.13-linux-glibc2.12-x86_64 [root@node101 ~]# [root@node101 ~]# ln -s /yinzhengjie/softwares/mysql-8.0.13-linux-glibc2.12-x86_64/ /yinzhengjie/softwares/mysql [root@node101 ~]# [root@node101 ~]# ll /yinzhengjie/softwares/ total 4 lrwxrwxrwx. 1 root root 59 Jan 16 05:57 mysql -> /yinzhengjie/softwares/mysql-8.0.13-linux-glibc2.12-x86_64/ drwxr-xr-x. 9 mysql mysql 4096 Jan 16 05:48 mysql-8.0.13-linux-glibc2.12-x86_64 [root@node101 ~]# [root@node101 ~]# cat ~/.bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin:/yinzhengjie/softwares/mysql/bin/ export PATH [root@node101 ~]# [root@node101 ~]# [root@node101 ~]# source ~/.bash_profile [root@node101 ~]#
4>.初始化MySQL数据库
[root@node101 ~]# mysqld --initialize --user=mysql --basedir=/yinzhengjie/softwares/mysql --datadir=/yinzhengjie/softwares/mysql/data & [1] 4106 [root@node101 ~]# 2019-01-16T14:00:24.941001Z 0 [System] [MY-013169] [Server] /yinzhengjie/softwares/mysql-8.0.13-linux-glibc2.12-x86_64/bin/mysqld (mysqld 8.0.13) initializing of server in progress as process 4106 2019-01-16T14:00:33.851566Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: bSaeurfCP5)? #注意，记住这里的临时密码！ 2019-01-16T14:00:40.575983Z 0 [System] [MY-013170] [Server] /yinzhengjie/softwares/mysql-8.0.13-linux-glibc2.12-x86_64/bin/mysqld (mysqld 8.0.13) initializing of server has completed [1]+ Done mysqld --initialize --user=mysql --basedir=/yinzhengjie/softwares/mysql --datadir=/yinzhengjie/softwares/mysql/data [root@node101 ~]# [root@node101 ~]# [root@node101 ~]# ll /yinzhengjie/softwares/mysql/data/ total 155708 -rw-r-----. 1 mysql mysql 56 Jan 16 06:00 auto.cnf -rw-------. 1 mysql mysql 1680 Jan 16 06:00 ca-key.pem -rw-r--r--. 1 mysql mysql 1112 Jan 16 06:00 ca.pem -rw-r--r--. 1 mysql mysql 1112 Jan 16 06:00 client-cert.pem -rw-------. 1 mysql mysql 1680 Jan 16 06:00 client-key.pem -rw-r-----. 1 mysql mysql 5753 Jan 16 06:00 ib_buffer_pool -rw-r-----. 1 mysql mysql 12582912 Jan 16 06:00 ibdata1 -rw-r-----. 1 mysql mysql 50331648 Jan 16 06:00 ib_logfile0 -rw-r-----. 1 mysql mysql 50331648 Jan 16 06:00 ib_logfile1 drwxr-x---. 2 mysql mysql 6 Jan 16 06:00 #innodb_temp drwxr-x---. 2 mysql mysql 4096 Jan 16 06:00 mysql -rw-r-----. 1 mysql mysql 25165824 Jan 16 06:00 mysql.ibd drwxr-x---. 2 mysql mysql 4096 Jan 16 06:00 performance_schema -rw-------. 1 mysql mysql 1680 Jan 16 06:00 private_key.pem -rw-r--r--. 1 mysql mysql 452 Jan 16 06:00 public_key.pem -rw-r--r--. 1 mysql mysql 1112 Jan 16 06:00 server-cert.pem -rw-------. 1 mysql mysql 1676 Jan 16 06:00 server-key.pem drwxr-x---. 2 mysql mysql 27 Jan 16 06:00 sys -rw-r-----. 1 mysql mysql 10485760 Jan 16 06:00 undo_001 -rw-r-----. 1 mysql mysql 10485760 Jan 16 06:00 undo_002 [root@node101 ~]# [root@node101 ~]#
5>.修改MySQL的配置文件
[root@node101 ~]# cat /etc/my.cnf [mysqld] basedir=/yinzhengjie/softwares/mysql/ datadir=/yinzhengjie/softwares/mysql/data/ [root@node101 ~]#
6>.拷贝MySQL的启动脚本到系统自启动路径下并启动MySQL服务
[root@node101 ~]# [root@node101 ~]# cp /yinzhengjie/softwares/mysql/support-files/mysql.server /etc/init.d/ [root@node101 ~]# [root@node101 ~]# /etc/init.d/mysql.server start Starting MySQL.Logging to '/yinzhengjie/softwares/mysql/data/node101.yinzhengjie.org.cn.err'. .

四.MySQL多实例安装
1>.将安装好的MySQL目录拷贝一份
