Mysql_二进制方式安装详解
mysql 安装
1.安装方式
1.二进制安装
2.源码包安装
3.rpm包安装
1.二进制安装
1）上传或者下载包
[root@db01 ~]# rz
#或者
[root@web01 ~]# wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.6.46-linux-glibc2.12-x86_64.tar.gz
2）安装依赖
先安装依耐，在解压之前安装，防止包在解压的时候就去找依耐，而出现安装报错的问题。
[root@db01 ~]# yum install -y ncurses-devel libaio-devel autoconf
3）解压包
[root@db01 ~]# tar xf mysql-5.6.46-linux-glibc2.12-x86_64.tar.gz
4）移动目录
一般用户安装的软件放在/usr/local/下面
[root@db01 ~]# mv mysql-5.6.46-linux-glibc2.12-x86_64 /usr/local/
主文件夹下的一些目录
[root@db01 /usr/local/mysql-5.6.46-linux-glibc2.12-x86_64]# ll

drwxr-xr-x 2 root root 136 Jul 9 10:34 support-files # 里面有默认的配置文件和启动脚本
5）做软连接
方便升级和管理目录
[root@db01 ~]# ln -s /usr/local/mysql-5.6.46-linux-glibc2.12-x86_64 /usr/local/mysql
6）创建mysql用户
用来管理mysql进程的
[root@db01 ~]# useradd mysql -s /sbin/nologin -M
7）拷贝配置文件和启动脚本
[root@db01 ~]# cd /usr/local/mysql/support-files/
[root@db01 support-files]# cp my-default.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y
[root@db01 support-files]# cp mysql.server /etc/init.d/mysqld
8）初始化数据库
[root@db01 ~]# cd /usr/local/mysql/scripts/
[root@db01 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两个ok
9）启动数据库
[root@db01 scripts]# /etc/init.d/mysqld start
10）配置环境变量
[root@db01 scripts]# vim /etc/profile.d/mysql.sh
export PATH=/usr/local/mysql/bin:$PATH
[root@db01 scripts]# source /etc/profile
11）配置system管理mysql
[root@db01 scripts]# vim /usr/lib/systemd/system/mysqld.service
