centos7安装mysql

1. 先下载mysql

   地址: mysql5.7-rpm.tar
 2. 可以用Xshell中的Xftp把下载后的文件上传到centos上,然后解压:
tar -xvf mysql-5.7.22-1.el7.x86_64.rpm-bundle.tar -C /usr/local/mysql5.7

解压完成后

 

 4. 安装依赖

yum -y install libaio-devel
yum -y install numactl-devel
yum -y install openssl-devel

3.然后安装

rpm -ivh mysql-community-common-5.7.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.22-1.el7.x86_64.rpm 
##rpm -ivh mysql-community-libs-compat-5.7.22-1.el7.x86_64.rpm  不用安装 
rpm -ivh mysql-community-client-5.7.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.22-1.el7.x86_64.rpm
##rpm -ivh mysql-community-server-minimal-5.7.22-1.el7.x86_64.rpm 不用安装

5. 初始化数据库

  会在/var/log/中生成日志文件

sudo mysqld --initialize

  查看密码

tail /var/log/mysqld.log

 6. 修改mysql数据库目录所属用户及所属组,然后启动数据库

sudo chown mysql:mysql /var/lib/mysql -R
systemctl start mysqld.service

7.修改数据库密码

[root@localhost mysql5.7]# mysql_secure_installation

 

下面根据需求选择。

8.下面可以测试

 

 

安装完成。

可通过一下命令查找需要安装的依赖包:

yum search getopt

然后输出的包可能比较多,对比给出的依赖包的信息,选择相应的包安装

安装命令:yum -y install perl-Getopt-Long.noarch 0:2.40-3.el7

注意:这一步rpm -ivh mysql-community-server-5.7.19-1.el6.x86_64.rp可能遇到报错

多数情况是缺少安装依赖的包,可以通过#yum search 包名; 来查找相应的包,然后通过命令:#yum -y install 找到的包名;

安装mysql-community-server时报如下错误ERROR:

 

 

 问题:缺少libnuma依赖包;

 

#查找libnuma的安装包:
[root@VM_59_155_centos package]# yum -y search libnuma
 
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
================================================= N/S matched: libnuma ==================================================
numactl-libs.i686 : libnuma libraries
numactl-libs.x86_64 : libnuma libraries
  Name and summary matches only, use "search all" for everything.
 
#安装
[root@VM_59_155_centos package]# yum -y install numactl-libs.x86_64
 
#再重新安装:mysql-community-server
rpm -ivh mysql-community-server-8.0.11-1.el7.x86_64.rpm
