centos7安装MYsql5.7 64位

第一步

在MySQL官网中下载YUM源rpm安装包：http://dev.mysql.com/downloads/repo/yum/

第二步

# 下载mysql源安装包

shell> wget http:

//dev

.mysql.com

/get/mysql57-community-release-el7-8

.noarch.rpm

# 安装mysql源

shell> yum localinstall mysql57-community-release-el7-8.noarch.rpm

检查mysql源是否安装成功

 yum repolist enabled | grep

"mysql.*-community.*"

第三步安装

yum install mysql-community-server

第四步启动

ystemctl start mysqld

第五步设置开机启动

systemctl

enable

mysqld

systemctldaemon-reload

第六步修改密码

mysql会有一个默认密码用命令：

sudo grep 'temporary password' /var/log/mysqld.log

[code]grep 'temporary password' /var/log/mysqld.log

[code]mysql -uroot -p

[code]ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';

或者

[code]set password for 'root'@'localhost'=password('MyNewPass4!');

（二）、安装redis

第一步：下载redis安装包

wget http://download.redis.io/releases/redis-4.0.6.tar.gz

[root@iZwz991stxdwj560bfmadtZ local]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz

2017-12-13 12:35:15 (608 KB/s) - ‘redis-4.0.6.tar.gz’ saved [1723533/1723533]

第二步：解压压缩包

tar -zxvf redis-4.0.6.tar.gz

[root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz

第三步：yum安装gcc依赖

yum install gcc

[root@iZwz991stxdwj560bfmadtZ local]# yum install gcc

遇到选择,输入y即可

第四步：跳转到redis解压目录下

cd redis-4.0.6

[root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6

第五步：编译安装

make MALLOC=libc　　

[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# make MALLOC=libc

将/usr/local/redis-4.0.6/src目录下的文件加到/usr/local/bin目录

cd src && make install

[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src && make install
CC Makefile.dep

Hint: It's a good idea to run 'make test' ;)

INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install

二、启动redis的三种方式

先切换到redis src目录下

[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src

1、直接启动redis

./redis-server

[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server
