由于工作需要,需要在一台装有 CentOS 系统的测试服务器上安装 mysql ,由于该服务器上存有其他比较重要的测试数据,所以不能连接外网。由于之前安装 MySQL 一直都是使用 yum 命令一键搞定的,所以手动安装的话还是有些麻烦的。所以在这里我将我在安装过程中遇到的一些问题记录下来。
1.需求就不用讲了,客户现场,政府环境,银行环境,大多是没网的,所以无网安装是很有必要的
mysql下载路径:https://dev.mysql.com/downloads/mysql/
查看自己Linux系统版本
[[email protected] ~]
# cat /etc/RedHat-release
CentOS Linux release 7.3.1611 (Core)
往下拉继续选择
选择对应的下载,mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar
这样几分钟就下载了。
2.准备依赖包:
a.numactl 软件包:
- numactl-2.0.9-6.el7_2.x86_64.rpm
- numactl-devel-2.0.9-6.el7_2.x86_64.rpm
- numactl-libs-2.0.9-6.el7_2.x86_64.rpm
b.其他相关支持:
- perl-Data-Dumper-2.145-3.el7.x86_64.rpm
- libaio-0.3.109-13.el7.x86_64.rpm
下载方式:https://pkgs.org
下面是下载路径:
libaio-0.3.109-13.el7.x86_64.rpm
perl-Data-Dumper-2.145-3.el7.x86_64.rpm
numactl-libs-2.0.9-6.el7_2.x86_64.rpm
numactl-devel-2.0.9-6.el7_2.x86_64.rpm
numactl-2.0.9-6.el7_2.x86_64.rpm

tar

numactl-2.0.9-6.el7_2.x86_64.rpm
4.安装
第一步,先安装依赖,安装 perl-Data-Dumper-2.145-3.el7.x86_64.rpm 和 libaio-0.3.109-13.el7.x86_64.rpm
[[email protected] ~]
# rpm -ivh libaio-0.3.109-13.el7.x86_64.rpm

第二步,继续安装 numactl相关
[[email protected] ~]
# rpm -ivh numactl*
Preparing...
################################# [100%]
package numactl-libs-2.0.9-6.el7_2.x86_64 is already installed
如果不安装这个包会报错,错误如下(本人未测试):
error: Failed dependencies:
libnuma.so.1()(64bit) is needed by mysql-community-server-5.7.18-1.el7.x86_64
libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-server-5.7.18-1.el7.x86_64
libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-server-5.7.18-1.el7.x86_64
若此时直接安装mysql,还会异常:
warning: mysql-community-libs-5.7.18-1.el7.x86_64.rpm: Header V3 DSA
/SHA1
Signature, key ID 5072e1f5: NOKEY error: Failed dependencies:
mysql-community-common(x86-64) >= 5.7.9 is needed by mysql-community-libs-5.7.18-1.el7.x86_64
mariadb-libs is obsoleted by mysql-community-libs-5.7.18-1.el7.x86_64
第一行还能看明白,是依赖问题,第二行的“mariadb-libs 被废弃”是什么鬼?废弃了为什么不提供一个新的还要出现这种弱智提示呢?经过一番搜寻,才发现是因为在CentOS 7上已经有一个mariadb 而这个会与 MySQL的mariadb发生冲突。所以此时我们需要将系统自带的mariadb卸载掉,然后使用mysql自带的mariadb。
接下来查看mariadb版本
[[email protected] ~]
# rpm -qa | grep mariadb
mariadb-libs-5.5.52-1.el7.x86_64
卸载系统安装的mariadb
[[email protected] ~]
# rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64
[[email protected] ~]
# rpm -qa | grep mariadb
[[email protected] ~]
#
解决好这个问题后,就可以安装mysql了,先解压mysql,并查看安装包

# tar -xf mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar

中间安装server时,又说必须安装client,至此,mysql安装成功,打完收工。

至此,无网安装难的历史已经结束,至少的我实验没问题了,好像还缺点是什么,数据库密码是啥?

这样就可以登录数据库了,try一下:
[[email protected] ~]
# mysql -u root

(using password: NO)
报错了,连输入密码的机会也没有。

登陆成功试试,数据库好使不
mysql> show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
不改密码,用不了,继续:
mysql> ALTER USER

@
‘localhost‘
IDENTIFIED BY
‘你的密码‘
;
Query OK, 0 rows affected (0.02 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)
然后再使用SQL就没问题了
mysql> show databases;
+--------------------+

| performance_schema |

+--------------------+
4 rows

(0.00 sec)
用数据库工具链接,出现问题:
不允许远程访问,改继续:
mysql> GRANT ALL PRIVILEGES ON *.* TO
‘root‘
@
‘%‘
IDENTIFIED BY
‘你的密码‘
WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
再试就没有问题了,至此数据库安装问题基本没有。
查看mysql配置文件地址:

查看字符集:
