这篇文章给大家分享的是有关RHEL 7.2如何安装二进制MySQL 5.7.18的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。
 
环境:
 
Red Hat Enterprise Linux Server release 7.2 (Maipo)
 
mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
 
安装需求:
 
libaio
 
MySQL 5.7.19 and later 需要安装libnuma,由于本次测试为5.7.18,不需要安装libnuma.
 
如之前安装过MySQL,清除一下目录和文件
 
/etc/my.cnf or the /etc/mysql
 
rhel7以后需要取消RemoveIPC限制
 
[root@rhelb mysql]# vi /etc/systemd/logind.conf
 
#RemoveIPC=yes -> RemoveIPC=no
 
检查软件包是否安装
 
[root@rhelb mysql]# rpm -qa | grep libaio
 
关闭防火墙
 
[root@rhelb yum.repos.d]# vi /etc/sysconfig/selinux
 
SELINUX=enforcing-> SELINUX=disabled
 
关闭系统THP,rhel7以后和之前关闭THP文件有变化,rhel7及以后关闭方式如下:
 
[root@rhelb yum.repos.d]# cat /sys/kernel/mm/transparent_hugepage/enabled
 
[always] madvise never
 
在quiet后添加 transparent_hugepage=never
 
[root@rhelb yum.repos.d]# cat /etc/default/grub
 
GRUB_TIMEOUT=5
 
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
 
GRUB_DEFAULT=saved
 
GRUB_DISABLE_SUBMENU=true
 
GRUB_TERMINAL_OUTPUT="console"
 
GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet transparent_hugepage=never"
 
GRUB_DISABLE_RECOVERY="true"
 
添加后重启主机
 
[root@rhelb yum.repos.d]# cat /sys/kernel/mm/transparent_hugepage/enabled
 
always madvise [never]
 
配置yum源,rhel7以后,新建一个新的yum资料库
 
[root@rhelb mysql]# mount /dev/sr0 /mnt
 
[root@rhelb yum.repos.d]# ls -lrt
 
total 8
 
-rw-r--r--. 1 root root  91 Aug 16 23:11 rhel.repo
 
-rw-r--r--. 1 root root 358 Aug 16 23:12 redhat.repo
 
[root@rhelb yum.repos.d]# more /etc/yum.repos.d/rhel.repo
 
[rhel7_server]
 
name=added from: file:///rhel7/dvd
 
baseurl=file:///mnt
 
enabled=1
 
gpgcheck=0
 
安装软件包:
 
[root@rhelb mysql]# yum -y install libaio.x86_64
 
......
 
Installed:
 
  libaio.x86_64 0:0.3.109-13.el7                                                                                                    
 
Complete!
 
MySQL二进制目录说明:
 
Directory Contents of Directory
bin mysqld server, client and utility programs
docs MySQL manual in Info format
man Unix manual pages
include Include (header) files
lib Libraries
share Error messages, dictionary, and SQL for database installation
support-files Miscellaneous support files
解压软件:
 
[root@rhelb soft]# tar -xzvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
 
[root@rhelb soft]# mv mysql-5.7.18-linux-glibc2.5-x86_64 /usr/local/mysql
 
创建相关用户:
 
[root@rhelb mysql]# groupadd mysql
 
[root@rhelb mysql]# useradd -r -g mysql -s /bin/false mysql
 
[root@rhelb mysql]# cd /usr/local
 
[root@rhelb local]# mkdir /data
 
[root@rhelb local]# chown -R mysql:mysql /usr/local/mysql/
 
[root@rhelb local]# chown -R mysql:mysql /data/
 
[root@rhelb local]# chmod 750 /data/
 
初始化数据库:
 
查看mysqld参数:
 
root@rhelb mysql]# bin/mysqld --verbose --help |more
 
mysqld: Can't change dir to '/var/lib/mysql/' (Errcode: 2 - No such file or directory)

配置ssl,会话安全方面考虑,如不需要可以不配置
 
[root@rhelb mysql]# bin/mysql_ssl_rsa_setup

配置参数文件,如果不配置[client]客户端连接时提示/tmp/socket.sock
 
[root@rhelb etc]# vi /etc/my.cnf
 
[mysqld]
 
port = 3306
 
pid-file = /data/mysql3306.pid
 
datadir = /data/
 
socket = /data/mysql3306.sock
 
slow_query_log_file = /data/slow.log
 
log-error = /data/error.log
 
[client]
 
socket = /data/mysql3306.sock   
 
MySQL取消安全隐患:
 
 a)为root用户设置密码
  b)删除匿名账号
  c)取消root用户远程登录
  d)删除test库和对test库的访问权限
  e)刷新授权表使修改生效
 
root@rhelb mysql]# bin/mysql_secure_installation
 
Securing the MySQL server deployment.
 
Enter password for user root:
 
Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
 
[root@rhelb mysql]# bin/mysql_secure_installation -S /data/mysql3306.sock
 
Securing the MySQL server deployment.
 
Enter password for user root:
 
Error: Access denied for user 'root'@'localhost' (using password: NO)
 
[root@rhelb mysql]# bin/mysql_secure_installation -S /data/mysql3306.sock
 
Securing the MySQL server deployment.
 
Enter password for user root:       <<——日志中临时生成的密码
 
The existing password for the user account root has expired. Please set a new password.
 
New password:
 
Re-enter new password:
 
VALIDATE PASSWORD PLUGIN can be used to test passwords
 
and improve security. It checks the strength of password
 
and allows the users to set only those passwords which are
 
secure enough. Would you like to setup VALIDATE PASSWORD plugin?
 
Press y|Y for Yes, any other key for No: Y
 
There are three levels of password validation policy:
 
LOW    Length >= 8
 
MEDIUM Length >= 8, numeric, mixed case, and special characters
 
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file
 
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1
 
Using existing password for root.
 
Estimated strength of the password: 100
 
Change the password for root ? ((Press y|Y for Yes, any other key for No) :    
 
 ... skipping.
 
By default, a MySQL installation has an anonymous user,
 
allowing anyone to log into MySQL without having to have
 
a user account created for them. This is intended only for
 
testing, and to make the installation go a bit smoother.
 
You should remove them before moving into a production
 
environment.
 
Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y
 
Success.
 
Normally, root should only be allowed to connect from
 
'localhost'. This ensures that someone cannot guess at
 
the root password from the network.
 
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y
 
Success.
 
By default, MySQL comes with a database named 'test' that
 
anyone can access. This is also intended only for testing,
 
and should be removed before moving into a production
 
environment.
 
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y
 
 - Dropping test database...
 
Success.
 
 - Removing privileges on test database...
 
Success.
 
Reloading the privilege tables will ensure that all changes
 
made so far will take effect immediately.
 
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y
 
Success.
 
All done!
 
 
配置服务启动:
 
[root@rhelb mysql]# cp support-files/mysql.server /etc/init.d/
 
[root@rhelb mysql]# service mysql.server start
 
Starting MySQL. SUCCESS!
