在CentOS7.4中安装MysqL
使用rpm安装MysqL
1.下载
下载地址:MySQL官网
下载bundle版本的安装包,如下图:
2.安装
解压安装包,一般安装sever和client就可以满足大部分需求
在安装server的时候要注意,Centos7自带了一个mariadb-lib的包,会和server包的内容冲突,因此要先删掉自带的mariadb-lib包;使用 rpm -qa|grep mariadb 命令检查,然后使用 yum remove mariadb-libs-5.5.52-1.el7.x86_64 删除即可
MysqL安装命令
rpm -ivh MysqL-server-5.6.20-1.rhel5.x86_64.rpm rpm -ivh MysqL-client-5.6.20-1.rhel5.x86_64.rpm rpm -ivh MysqL-devel-5.6.20-1.rhel5.x86_64.rpm
安装server出现的错误
[root@iz8vbevzhhalyp6vtmayu2z install]# rpm -ivh MysqL-server-5.6.20-1.rhel5.x86_64.rpm error: Failed dependencies: libaio.so.1()(64bit) is needed by MysqL-server-5.6.20-1.rhel5.x86_64 libaio.so.1(LIBAIO_0.1)(64bit) is needed by MysqL-server-5.6.20-1.rhel5.x86_64 libaio.so.1(LIBAIO_0.4)(64bit) is needed by MysqL-server-5.6.20-1.rhel5.x86_64
从以上错误信息可以看出是缺少库libaio,所以需要安装libaio
下载libaio:点击下载
rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm
安装完成后就可以安装server了
安装server又出现如下错误
[root@iz8vbevzhhalyp6vtmayu2z install]# rpm -ivh MysqL-server-5.6.20-1.rhel5.x86_64.rpm Preparing... ################################# [100%] Updating / installing... 1:MysqL-server-5.6.20-1.rhel5 ################################# [100%] warning: user MysqL does not exist - using root warning: group MysqL does not exist - using root FATAL ERROR: please install the following Perl modules before executing /usr/bin/MysqL_install_db: Data::Dumper
从以上错误信息看出应该需要安装库perl
yum install -y perl-Module-Install.noarch
安装完之后继续安装server,到此MysqL安装完了
3.初始化MysqL及设置密码
启动MysqL
systemctl start MysqL #Centos7开始使用systemctl的方式管理服务
查看root账号的密码及设置新密码
cat /root/.MysqL_secret MysqL -uroot -p获取的密码 set password = password('新密码'); exit;
4.允许远程连接
grant all privileges on *.* to 'root'@'%' identified by 'password' with grant option; flush privileges;
