二进制安装MySQL

下载mysql包,也可以自己上传到机器

[ ~]# wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.6.46-linux-glibc2.12-x86_64.tar.gz

一.安装

1.安装依赖
yum install -y ncurses-devel libaio-devel gcc gcc-c++ glibc cmake autoconf

2.解雅tgz的包
[ ~]# tar xf mysql-5.6.46-linux-glibc2.12-x86_64.tar.gz

3.移动目录
[ ~]# mv mysql-5.6.46-linux-glibc2.12-x86_64 /usr/local/

4.做软链接
[ ~]# ln -s /usr/local/mysql-5.6.46-linux-glibc2.12-x86_64 /usr/local/mysql

5.创建mysql用户
[ ~]# useradd mysql -s /sbin/nologin -M

6.拷贝配置文件和启动脚本
[ support-files]# cp my-default.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y

[ support-files]# cp mysql.server /etc/init.d/mysqld


7.初始化数据库

[ ~]# cd /usr/local/mysql/scripts/
[ scripts]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

--user:    指定用户
--basedir: 指定安装目录
--datadir: 指定数据目录

#初始化成功的标志是有两个ok,再看最后有没有error

二.配置环境和systemctl管理

8.配置环境变量
[ scripts]# vim /etc/profile.d/mysql.sh
export PATH=/usr/local/mysql/bin:$PATH

[ scripts]# source /etc/profile


9.配置systemctl管理mysql

[ scripts]# vim /usr/lib/systemd/system/mysqld.service

LimitNOFILE = 5000

[ scripts]# systemctl daemon-reload

三.启动数据库
