1> 关闭防火墙和selinux
关闭防火墙
service iptables stop
chkconfig --level 345 iptables off
关闭selinux
setenforce 0
cat etc/SELINUX/config | grep selinux=
查看结果是否为selinux=disabled
2>创建MySQL用户
groupadd -g 54330 mysql
useradd -u 54330 -g mysql mysql
cd /u01/mysql
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz
tar -xzvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.7.21-linux-glibc2.12-x86_64 mysql57
mkdir mysqldata
chown -R mysql:mysql /u01/mysql/
修改root，mysql等用户环境变量
root用户在/root下 .bash_profile
mysql用户在/home/mysql下
PATH=$PATH:/u01/mysql/mysql57/bin
export PATH
3>修改系统参数
root用户修改参数
vi /etc/security/limits.conf
mysql soft nproc 16384
mysql hard nproc 16384
mysql soft nofile 65536
mysql hard nofile 65536
mysql soft stack 1024000
mysql hard stack 1024000
切换到mysql用户
su - mysql
mkdir -p /u01/mysql/mysqldata/3306
mkdir -p /u01/mysql/mysqldata/3306/mybinlog
mkdir -p /u01/mysql/mysqldata/3306/mydata_1
mkdir -p /u01/mysql/mysqldata/3306/mytmp
mkdir -p /u01/mysql/mysqldata/3306/mylog
su - root
chmod +x /u01/mysql/mysql57/bin/mysqld
4> 初始化
/u01/mysql/mysql57/bin/mysqld --initialize --user=mysql --basedir=/u01/mysql/mysql57 --datadir=/u01/mysql/mysqldata/3306/mydata --innodb-undo-tablespaces=4
记下密码，后面登陆使用
数据加密
/u01/mysql/mysql57/bin/mysql_ssl_rsa_setup --datadir=/u01/mysql/mysqldata/3306/mydata
先root用户赋予权限 chown mysql:mysql /etc/my.cnf
登录mysql
配置/etc/my.cnf
[client]
default-character-set = utf8
[mysql]
prompt = [\\u@\\h][\\d]>
[mysqld]

5> mysql用户下拉起服务
mysqld_safe --defaults-file=/u01/mysql/mysqldata/3306/my.cnf &
alter user 'root'@'localhost' identified by '123456';
起停
mysqld_safe --defaults-file=/u01/mysql/mysqldata/3306/my.cnf &
mysqladmin -uroot -p shutdown
