一.环境

CentOS7.4   64位  最小化安装

二.准备工作

1.安装依赖

yum -y install wget cmake gcc gcc-c++ ncurses ncurses-devel libaio-devel openssl openssl-devel

2.下载源码包

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-boost-8.0.11.tar.gz

3.创建mysql用户

groupadd mysql

useradd-r -g mysql -s /bin/false mysql

4.创建安装目录和数据目录

mkdir -p /usr/local/mysql

mkdir-p /data/mysql

三.安装MySQL8.0.11

1.解压源码包

tar -zxf mysql-boost-8.0.11.tar.gz -C /usr/local

2.编译&安装

cd /usr/local/mysql-8.0.11cmake .-DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DMYSQL_TCP_PORT=3306 -DWITH_BOOST=/usr/local/mysql-8.0.11/boost

make&& make install

3.配置my.cnf文件

vi /etc/my.cnf

[mysqld]

server-id=1port=3306basedir=/usr/local/mysql

datadir=/data/mysql

skip-grant-tables#第一次启动使用免密登陆，之后可以注释掉

4.目录权限修改

chown -R mysql:mysql /usr/local/mysql

chown-R mysql:mysql /data/mysql

chmod755 /usr/local/mysql -R

chmod755 /data/mysql -R

5.初始化

bin/mysqld --initialize --user=mysql --datadir=/data/mysql/bin/mysql_ssl_rsa_setup

6.启动mysql

bin/mysqld_safe &

7.修改账号密码

bin/mysql -uroot -p

输入回车可以直接登录

mysql> alter user 'root'@'localhost' identified by "123456";

修改密码时候可能会出现

The MySQL server is running with the--skip-grant-tables option

异常

此时输入

mysql> flush privileges;

出现 Query OK, 0 rows affected (0.01 sec)

之后再输入修改密码的sql就可以了

8.添加远程登陆账号

mysql> create user root@'%' identified by '123456';

Query OK,0 rows affected (0.08sec)

mysql> grant all privileges on *.* to root@'%';

Query OK,0 rows affected (0.04sec)

mysql>flush privileges;

Query OK,0 rows affected (0.01 sec)

9.创建软链接

ln -s /usr/local/mysql/bin/*/usr/local/bin/

10.添加到启动(非必要)

cp support-files/mysql.server /etc/init.d/mysql.server
