centos7.3中RPM方式安装mysql5.7

首先去下载rpm安装包：https://dev.mysql.com/downloa...，选择红帽linux64位版。然后上传到服务器中。

[root@cs MysqL]# ls
MysqL-community-client-5.7.20-1.el7.x86_64.rpm  MysqL-community-embedded-5.7.20-1.el7.x86_64.rpm         MysqL-community-libs-5.7.20-1.el7.x86_64.rpm               MysqL-community-server-5.7.20-1.el7.x86_64.rpm
MysqL-community-common-5.7.20-1.el7.x86_64.rpm  MysqL-community-embedded-compat-5.7.20-1.el7.x86_64.rpm  MysqL-community-libs-compat-5.7.20-1.el7.x86_64.rpm        MysqL-community-server-minimal-5.7.20-1.el7.x86_64.rpm
MysqL-community-devel-5.7.20-1.el7.x86_64.rpm   MysqL-community-embedded-devel-5.7.20-1.el7.x86_64.rpm   MysqL-community-minimal-debuginfo-5.7.20-1.el7.x86_64.rpm  MysqL-community-test-5.7.20-1.el7.x86_64.rpm

接下来就是安装了,如果是普通用户需要sudo权限，并在执行命令前加sudo。如果安装过MysqL先用命令卸载掉相关的包。rpm安装是有依赖关系的所以我们要按照顺序进行安装：

[root@cs MysqL]# rpm -ivh MysqL-community-common-5.7.20-1.el7.x86_64.rpm 
warning: MysqL-community-common-5.7.20-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature,key ID 5072e1f5: NOKEY
Preparing...                          ################################# [100%]
    file /usr/share/MysqL/czech/errmsg.sys from install of MysqL-community-common-5.7.20-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.52-1.el7.x86_64

提示和我们安装的有冲突，我们找到这个包并卸载掉：

[root@cs MysqL]# rpm -qa|grep mariadb
mariadb-libs-5.5.52-1.el7.x86_64
[root@cs MysqL]# rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64

再次安装：

error: Failed dependencies:
    libaio.so.1()(64bit) is needed by MysqL-community-server-5.7.20-1.el7.x86_64

提示安装失败，这是因为我们少这个依赖库，用yum进行安装：

Complete!

再次安装：

[root@cs MysqL]# rpm -ivh MysqL-community-server-5.7.20-1.el7.x86_64.rpm

到此，安装完成。然后我们进行初始化数据库，因为我是root安装的所以想要指定一个MysqL用，用MysqL启动。根据自己的需要也可以不加。初始化：

[root@cs MysqL]# MysqLd --initialize --user=MysqL

启动数据库并：

[root@cs MysqL]# systemctl start MysqLd

设置开机自动启动并查看是否设置成功：

[root@cs MysqL]# systemctl enable MysqLd
[root@cs MysqL]# systemctl is-enabled MysqLd
enabled

因为MysqL5.7的会有一个随机密码在日志中生成，我们查找一下，密码这语句的最后：

[root@cs MysqL]# grep 'temporary password' /var/log/MysqLd.log
2017-11-17T08:05:05.411354Z 1 [Note] A temporary password is generated for root@localhost: Ret6HK7sab<a

然后我们就可以用密码登陆数据库，并@R_403_360@或增加远程访问权限了：

set password for 'root'@'localhost'=password('666666');
GRANT ALL PRIVILEGES ON *.* TO 'name'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;FLUSH PRIVILEGES;

小写部分为@R_403_360@；大写部分为设置远程登陆权限。大功告成！
