一.前言

linux安装软件的方式多种多样，MySQL也不例外，本文将介绍MySQL所有的安装方式。

二.关于MySQL的安装

MySQL一般可以采用四种安装方式，每种方式各有优点，使用场景各有不同：

yum安装MySQL，优点：简单，方便，适用场景：可以访问网络的环境
离线源码编译安装MySQL，优点：可定制，适用性强，适用场景：无网络，需要定制MySQL，平台兼容性不强（内存最好大于4G不然编译会出现内存不足的报错）
RPM包安装MySQL，优点：简单，方便，适用场景：redhat系统
通用二进制包安装MySQL，优点：简单，好维护，适用场景：大部分环境都适用(推荐)

三.部署规划

3.1 服务器规划

服务器	操作系统版本	CPU架构	MySQL安装方式
node6	CentOS Linux release 7.4.1708	x86_64	源码编译安装MySQL
node7	CentOS Linux release 7.4.1708	x86_64	通用二进制包安装MySQL
node8	CentOS Linux release 7.4.1708	x86_64	RPM包安装MySQL
node9	CentOS Linux release 7.4.1708	x86_64	yum安装MySQL

3.2 数据库目录规划

文件类型	文件部署位置
数据目录datadir	/data/data（/data目录请确保足够大）
配置文件my.cnf	/etc/my.cnf
错误日志log-error	/data/log/mysql_error.log
二进制日志log-bin	/data/binlogs/mysql-bin(用于数据库恢复和主从复制，以及审计（audit）操作)
慢查询日志slow_query_log_file	/data/log/mysql_slow_query.log
套接字文件socket	/data/run/mysql.sock
进程ID文件mysql.pid	/data/run/mysql.pid

五.通用二进制包安装MySQL

5.1 上传MySQL通用二进制安装包到node7的/usr/local/class="lazy" data-src目录下

[root@node7 class="lazy" data-src]# pwd
/usr/local/class="lazy" data-src
[root@node7 class="lazy" data-src]# ls
mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz

5.2 解压MySQL到指定目录并改名

[root@node7 class="lazy" data-src]# tar -zxf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
[root@node7 class="lazy" data-src]# cd /usr/local/
[root@node7 local]# ls

[root@node7 local]# mv mysql-5.7.26-linux-glibc2.12-x86_64 mysql
[root@node7 local]# ls
bin  etc  games  include  lib  lib64  libexec  mysql  sbin  share  class="lazy" data-src

5.3 创建MySQL用户和用户组

[root@node7 local]# groupadd -g 1111 mysql
[root@node7 local]# useradd -g mysql -u 1111 -s /sbin/nologin mysql
[root@node7 local]# id mysql    #查看用户信息
uid=1111(mysql) gid=1111(mysql) groups=1111(mysql)

5.4 配置MySQL的bin目录到PATH路径

[root@node7 local]# echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
[root@node7 local]# source /etc/profile
[root@node7 local]# mysql    #输入MySQL之后双击tab键，即可列出候选MySQL命令
mysql                       mysql_client_test_embedded  mysqld-debug                mysqldumpslow               mysql_plugin                mysqlslap                   mysql_upgrade

5.5 创建MySQL数据存放目录

[root@node7 ~]# mkdir -p /data/{data,log,binlogs,run}
[root@node7 ~]# tree /data    #如果没有tree命令，则yum -y install tree安装
/data
├── binlogs
├── data
├── log
└── run

4 directories, 0 files
[root@node7 ~]# chown -R mysql:mysql /data
[root@node7 ~]# ll /data/
total 0
drwxr-xr-x 2 mysql mysql 6 Dec  3 11:07 binlogs
drwxr-xr-x 2 mysql mysql 6 Dec  3 11:07 data
drwxr-xr-x 2 mysql mysql 6 Dec  3 11:07 log
drwxr-xr-x 2 mysql mysql 6 Dec  3 11:07 run

5.6 配置MySQL配置文件

[root@node7 mysql]# rm -rf /etc/my.cnf
[root@node7 mysql]# touch /etc/my.cnf
#my.cnf配置文件详解，请查看我上一篇blog的#https://www.cnblogs.com/renshengdezheli/p/11913248.html的“MySQL配置文件优化参考”

5.7 初始化MySQL数据库

[root@node7 mysql]# mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/data
[root@node7 mysql]# echo $?
0
[root@node7 mysql]# grep "temporary password" /data/log/mysql_error.log    #查看MySQL初始化密码
2019-12-03T03:47:42.639938Z 1 [Note] A temporary password is generated for root@localhost: lhrh>J,p<8gw

5.8 生成ssl（可选）

#关于MySQL开启ssl查看https://www.cnblogs.com/mysql-dba/p/7061300.html
[root@node7 mysql]# mysql_ssl_rsa_setup --basedir=/usr/local/mysql --datadir=/data/data

5.11 进行MySQL安全初始化(可选)

[root@node7 system]# mysql_secure_installation 

Securing the MySQL server deployment.

Enter password for user root:    #这里输入MySQL初始化时生成的密码（grep "temporary password" /data/log/mysql_error.log）

The existing password for the user account root has expired. Please set a new password.

New password:   #输入新密码

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: n   #y安装MySQL密码插件
Using existing password for root.
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n

 ... 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  #y移除匿名用户
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) : n  #是否允许root远程登录

 ... skipping.
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  #是否移除test数据库
 - 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  #刷新权限表
Success.

All done!

5.12 修改密码，给用户赋权限（根据自己情况赋权限）

[root@node7 ~]# mysql -uroot -p111111

affiliates. Other names may be trademarks of their respective
owners.

Type "help;" or "h" for help. Type "c" to clear the current input statement.

mysql> SET PASSWORD = PASSWORD("123456");#修改root密码为123456，如果提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements，则说明密码设置太简单，如果想设置123456这样的简单密码，可在SQL中执行：
	#mysql> set global validate_password_policy=0;
	#mysql> set global validate_password_length=1;
	#这样再次执行SET PASSWORD = PASSWORD("123456")就可成功。

--------------------------------------------------------------------------------------
#以下是为MySQL赋权限的介绍
mysql> grant 权限1,权限2,…权限n on 数据库名称.表名称 to 用户名@用户地址 identified by ‘连接口令’;
权限1,权限2,…权限n代表select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file等14个权限。
当权限1,权限2,…权限n被all privileges或者all代替，表示赋予用户全部权限。
当数据库名称.表名称被*.*代替，表示赋予用户操作服务器上所有数据库所有表的权限。
用户地址可以是localhost，也可以是ip地址、机器名字、域名。也可以用’%"表示从任何地址连接。
‘连接口令’不能为空，否则创建失败。
比如：
mysql>grant select,insert,update,delete,create,drop on vtdc.employee to joe@10.163.225.87 identified by ‘123′;
给来自10.163.225.87的用户joe分配可对数据库vtdc的employee表进行select,insert,update,delete,create,drop等操作的权限，并设定口令为123。
 
mysql>grant all privileges on vtdc.* to joe@10.163.225.87 identified by ‘123′;
给来自10.163.225.87的用户joe分配可对数据库vtdc所有表进行所有操作的权限，并设定口令为123。
--------------------------------------------------------------------------------------

5.13 导入时区信息到MySQL库

[root@node7 system]# mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -uroot -p111111 mysql
#执行上述操作之后，time_zone，time_zone_leap_second，time_zone_name，time_zone_transition   ，time_zone_transition_type表就有时区数据了

5.16 利用logrotate对MySQL日志进行轮转(日志自动备份切割)

#logrotate配置详解请查看：https://www.linuxidc.com/Linux/2019-02/157099.htm
[root@node7 ~]# touch /root/.my.cnf
[root@node7 ~]# vim /root/.my.cnf

[root@node7 ~]# chmod 600 /root/.my.cnf 
[root@node7 ~]# cp /usr/local/mysql/support-files/mysql-log-rotate /etc/logrotate.d/
[root@node7 ~]# chmod 644 /etc/logrotate.d/mysql-log-rotate 
[root@node7 ~]# vim /etc/logrotate.d/mysql-log-rotate 
[root@node7 ~]# cat /etc/logrotate.d/mysql-log-rotate 
# The log file name and location can be set in
# /etc/my.cnf by setting the "log-error" option
# in either [mysqld] or [mysqld_safe] section as
# follows:
#
# [mysqld]
# log-error=/usr/local/mysql/data/mysqld.log
#
# In case the root user has a password, then you
# have to create a /root/.my.cnf configuration file
# with the following content:
#
# [mysqladmin]
# password =  
# user= root
#
# where "" is the password. 
#
# ATTENTION: The /root/.my.cnf file should be readable
# _ONLY_ by root !

/data/log/mysql_*.log {
        # create 600 mysql mysql
        notifempty  #当日志文件为空时，不进行轮转
        daily  #默认每一天执行一次rotate轮转工作
        rotate 52  #保留多少个日志文件(轮转几次).默认保留四个.就是指定日志文件删除之前轮转的次数，0 指没有备份，此处表示保留52天的日志
        missingok   #如果日志文件丢失，不要显示错误
        compress    #通过gzip 压缩转储以后的日志
    postrotate   #执行的指令

    endscript
}
[root@node7 ~]#

自此，通用二进制包安装MySQL完毕。

六.使用RPM包安装MySQL

6.1 上传MySQL的RPM包到/usr/local/class="lazy" data-src目录下

[root@node8 local]# cd /usr/local/class="lazy" data-src/
[root@node8 class="lazy" data-src]# ls
mysql-community-client-5.7.23-1.el7.x86_64.rpm  mysql-community-libs-5.7.23-1.el7.x86_64.rpm
mysql-community-common-5.7.23-1.el7.x86_64.rpm  mysql-community-libs-compat-5.7.23-1.el7.x86_64.rpm
mysql-community-devel-5.7.23-1.el7.x86_64.rpm   mysql-community-server-5.7.23-1.el7.x86_64.rpm

6.2 安装RPM包

[root@node8 class="lazy" data-src]# rpm -ivh ./*.rpm
warning: ./mysql-community-client-5.7.23-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

--------------------------------------------------------------------------------------
#以下是为MySQL赋权限的介绍
mysql> grant 权限1,权限2,…权限n on 数据库名称.表名称 to 用户名@用户地址 identified by ‘连接口令’;
权限1,权限2,…权限n代表select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file等14个权限。
当权限1,权限2,…权限n被all privileges或者all代替，表示赋予用户全部权限。
当数据库名称.表名称被*.*代替，表示赋予用户操作服务器上所有数据库所有表的权限。
用户地址可以是localhost，也可以是ip地址、机器名字、域名。也可以用’%"表示从任何地址连接。
‘连接口令’不能为空，否则创建失败。
比如：
mysql>grant select,insert,update,delete,create,drop on vtdc.employee to joe@10.163.225.87 identified by ‘123′;
给来自10.163.225.87的用户joe分配可对数据库vtdc的employee表进行select,insert,update,delete,create,drop等操作的权限，并设定口令为123。
 
mysql>grant all privileges on vtdc.* to joe@10.163.225.87 identified by ‘123′;
给来自10.163.225.87的用户joe分配可对数据库vtdc所有表进行所有操作的权限，并设定口令为123。
--------------------------------------------------------------------------------------

自此MySQL的RPM安装就完毕了，此方法自动生成/etc/my.cnf,查看配置文件可知道MySQL的日志目录和数据目录。

七.使用yum安装MySQL

7.1 下载并安装MySQL官方的 Yum Repository

[root@node9 ~]# wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
