1、下载二进制安装包 mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz
cd /usr/local/src
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz
2、解压，创建用户
[root@8d83e8f22faa src]# tar -xzvf mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz
[root@8d83e8f22faa src]# ll
total 629300
drwxr-xr-x. 9 root root 129 Sep 4 13:41 mysql-5.7.23-linux-glibc2.12-x86_64
-rw-r--r--. 1 root root 644399365 Sep 4 13:38 mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz
[root@8d83e8f22faa src]# mv mysql-5.7.23-linux-glibc2.12-x86_64 /usr/local/mysql
[root@8d83e8f22faa src]# cd /usr/local/mysql/
[root@8d83e8f22faa mysql]# ll

[root@8d83e8f22faa mysql]# groupadd mysql //创建用户组mysql
[root@8d83e8f22faa mysql]# useradd -r -g mysql mysql //-r参数表示mysql用户是系统用户，不可用于登录系统，创建用户mysql并将其添加到用户组mysql中
[root@8d83e8f22faa mysql]# chown -R mysql ../mysql/
[root@8d83e8f22faa mysql]# chgrp -R mysql ../mysql/
3、创建配置文件
cat > /etc/my.cnf << EOF
[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mysql/mysqld.log
#pid-file=/var/run/mysqld/mysqld.pid --会有问题

max_connections=5000
default-time_zone = '+8:00'
EOF
4、初始化数据库
[root@8d83e8f22faa mysql]# yum install libaio numactl
[root@8d83e8f22faa log]# touch mysqld.log
[root@8d83e8f22faa log]# chown -R mysql:mysql mysqld.log
[root@8d83e8f22faa log]# vi /root/.bash_profile #增加mysql的bin目录
PATH=/usr/local/mysql/bin:/data/mysql/lib:$PATH
export PATH
[root@8d83e8f22faa log]#
[root@8d83e8f22faa log]#
[root@8d83e8f22faa log]# source /root/.bash_profile
[root@8d83e8f22faa log]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --lc_messages_dir=/usr/local/mysql/share --lc_messagges=en_US
5、查看初始密码
[root@8d83e8f22faa log]# cat mysqld.log
