开始安装：
1、CentOS7默认安装了MariaDB数据库，首先将卸载掉。
[root@izuf6in4w20dqvk2nrs45kz ~]# rpm -qa | grep mariadb mariadb-libs-5.5.56-2.el7.x86_64 [root@izuf6in4w20dqvk2nrs45kz ~]# rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64 [root@izuf6in4w20dqvk2nrs45kz ~]# rpm -qa | grep mariadb [root@izuf6in4w20dqvk2nrs45kz ~]#
2、YUM安装依赖包及所需的编译工具（cmake）；不管有没有装过统一都安装下，避免有问题。
[root@izuf6in4w20dqvk2nrs45kz ~]# yum install -y make gcc-c++ cmake bison-devel ncurses-devel autoconf Loaded plugins: fastestmirror base | 3.6 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/3): epel/x86_64/updateinfo | 880 kB 00:00:00 (2/3): updates/7/x86_64/primary_db | 6.0 MB 00:00:00 (3/3): epel/x86_64/primary_db | 6.2 MB 00:00:00 Loading mirror speeds from cached hostfile Package 1:make-3.82-23.el7.x86_64 already installed and latest version Resolving Dependencies --> Running transaction check ---> Package autoconf.noarch 0:2.69-11.el7 will be installed --> Processing Dependency: perl(Data::Dumper) for package: autoconf-2.69-11.el7.noarch ---> Package bison-devel.x86_64 0:3.0.4-1.el7 will be installed ---> Package cmake.x86_64 0:2.8.12.2-2.el7 will be installed --> Processing Dependency: libarchive.so.13()(64bit) for package: cmake-2.8.12.2-2.el7.x86_64 ---> Package gcc-c++.x86_64 0:4.8.5-16.el7_4.1 will be installed --> Processing Dependency: libstdc++-devel = 4.8.5-16.el7_4.1 for package: gcc-c++-4.8.5-16.el7_4.1.x86_64 ---> Package ncurses-devel.x86_64 0:5.9-14.20130511.el7_4 will be installed --> Running transaction check ---> Package libarchive.x86_64 0:3.1.2-10.el7_2 will be installed ---> Package libstdc++-devel.x86_64 0:4.8.5-16.el7_4.1 will be installed ---> Package perl-Data-Dumper.x86_64 0:2.145-3.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ============================================================================================================================================================ Package Arch Version Repository Size ============================================================================================================================================================ Installing: autoconf noarch 2.69-11.el7 base 701 k bison-devel x86_64 3.0.4-1.el7 base 23 k cmake x86_64 2.8.12.2-2.el7 base 7.1 M gcc-c++ x86_64 4.8.5-16.el7_4.1 updates 7.2 M ncurses-devel x86_64 5.9-14.20130511.el7_4 updates 712 k Installing for dependencies: libarchive x86_64 3.1.2-10.el7_2 base 318 k libstdc++-devel x86_64 4.8.5-16.el7_4.1 updates 1.5 M perl-Data-Dumper x86_64 2.145-3.el7 base 47 k Transaction Summary ============================================================================================================================================================ Install 5 Packages (+3 Dependent packages) Total download size: 17 M Installed size: 56 M Downloading packages: (1/8): bison-devel-3.0.4-1.el7.x86_64.rpm | 23 kB 00:00:00 (2/8): autoconf-2.69-11.el7.noarch.rpm | 701 kB 00:00:00 (3/8): libarchive-3.1.2-10.el7_2.x86_64.rpm | 318 kB 00:00:00 (4/8): gcc-c++-4.8.5-16.el7_4.1.x86_64.rpm | 7.2 MB 00:00:00 (5/8): ncurses-devel-5.9-14.20130511.el7_4.x86_64.rpm | 712 kB 00:00:00 (6/8): libstdc++-devel-4.8.5-16.el7_4.1.x86_64.rpm | 1.5 MB 00:00:00 (7/8): perl-Data-Dumper-2.145-3.el7.x86_64.rpm | 47 kB 00:00:00 (8/8): cmake-2.8.12.2-2.el7.x86_64.rpm | 7.1 MB 00:00:00 ------------------------------------------------------------------------------------------------------------------------------------------------------------ Total 43 MB/s | 17 MB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Warning: RPMDB altered outside of yum. ** Found 2 pre-existing rpmdb problem(s), 'yum check' output follows: 2:postfix-2.10.1-6.el7.x86_64 has missing requires of libmysqlclient.so.18()(64bit) 2:postfix-2.10.1-6.el7.x86_64 has missing requires of libmysqlclient.so.18(libmysqlclient_18)(64bit) Installing : libstdc++-devel-4.8.5-16.el7_4.1.x86_64 1/8 Installing : libarchive-3.1.2-10.el7_2.x86_64 2/8 Installing : perl-Data-Dumper-2.145-3.el7.x86_64 3/8 Installing : autoconf-2.69-11.el7.noarch 4/8 Installing : cmake-2.8.12.2-2.el7.x86_64 5/8 Installing : gcc-c++-4.8.5-16.el7_4.1.x86_64 6/8 Installing : bison-devel-3.0.4-1.el7.x86_64 7/8 Installing : ncurses-devel-5.9-14.20130511.el7_4.x86_64 8/8 Verifying : autoconf-2.69-11.el7.noarch 1/8 Verifying : perl-Data-Dumper-2.145-3.el7.x86_64 2/8 Verifying : libarchive-3.1.2-10.el7_2.x86_64 3/8 Verifying : gcc-c++-4.8.5-16.el7_4.1.x86_64 4/8 Verifying : cmake-2.8.12.2-2.el7.x86_64 5/8 Verifying : ncurses-devel-5.9-14.20130511.el7_4.x86_64 6/8 Verifying : bison-devel-3.0.4-1.el7.x86_64 7/8 Verifying : libstdc++-devel-4.8.5-16.el7_4.1.x86_64 8/8 Installed: autoconf.noarch 0:2.69-11.el7 bison-devel.x86_64 0:3.0.4-1.el7 cmake.x86_64 0:2.8.12.2-2.el7 gcc-c++.x86_64 0:4.8.5-16.el7_4.1 ncurses-devel.x86_64 0:5.9-14.20130511.el7_4 Dependency Installed: libarchive.x86_64 0:3.1.2-10.el7_2 libstdc++-devel.x86_64 0:4.8.5-16.el7_4.1 perl-Data-Dumper.x86_64 0:2.145-3.el7 Complete!
3、创建MySQL用户和组(用户属性为禁止登录及不创建家目录）
[root@izuf6in4w20dqvk2nrs45kz ~]# useradd -s /sbin/nologin -M mysql
4、进入软件包存放目录解压安装包并进入解压后的软件目录内
[root@izuf6in4w20dqvk2nrs45kz ~]# cd /usr/src/ [root@izuf6in4w20dqvk2nrs45kz src]# ll total 31448 drwxr-xr-x. 2 root root 4096 Nov 5 2016 debug drwxr-xr-x. 2 root root 4096 Nov 5 2016 kernels -rw-r--r-- 1 root root 32192348 Jan 25 10:30 mysql-5.6.36.tar.gz [root@izuf6in4w20dqvk2nrs45kz src]# tar -zxf mysql-5.6.36.tar.gz [root@izuf6in4w20dqvk2nrs45kz src]# ll total 31452 drwxr-xr-x. 2 root root 4096 Nov 5 2016 debug drwxr-xr-x. 2 root root 4096 Nov 5 2016 kernels drwxr-xr-x 33 7161 31415 4096 Mar 18 2017 mysql-5.6.36 -rw-r--r-- 1 root root 32192348 Jan 25 10:30 mysql-5.6.36.tar.gz [root@izuf6in4w20dqvk2nrs45kz src]# cd mysql-5.6.36 [root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# ll total 324 drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 BUILD drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 client drwxr-xr-x 4 7161 31415 4096 Mar 18 2017 cmake -rw-r--r-- 1 7161 31415 21864 Mar 18 2017 CMakeLists.txt drwxr-xr-x 3 7161 31415 4096 Mar 18 2017 cmd-line-utils -rw-r--r-- 1 7161 31415 19838 Mar 18 2017 config.h.cmake -rw-r--r-- 1 7161 31415 40929 Mar 18 2017 configure.cmake -rw-r--r-- 1 7161 31415 17987 Mar 18 2017 COPYING drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 dbug drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 Docs -rw-r--r-- 1 7161 31415 65958 Mar 18 2017 Doxyfile-perfschema drwxr-xr-x 3 7161 31415 4096 Mar 18 2017 extra drwxr-xr-x 4 7161 31415 4096 Mar 18 2017 include -rw-r--r-- 1 7161 31415 333 Mar 18 2017 INSTALL drwxr-xr-x 7 7161 31415 4096 Mar 18 2017 libevent drwxr-xr-x 3 7161 31415 4096 Mar 18 2017 libmysql drwxr-xr-x 3 7161 31415 4096 Mar 18 2017 libmysqld drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 libservices drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 man drwxr-xr-x 10 7161 31415 4096 Mar 18 2017 mysql-test drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 mysys drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 mysys_ssl drwxr-xr-x 17 7161 31415 4096 Mar 18 2017 packaging drwxr-xr-x 11 7161 31415 4096 Mar 18 2017 plugin -rw-r--r-- 1 7161 31415 2496 Mar 18 2017 README drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 regex drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 scripts drwxr-xr-x 4 7161 31415 20480 Mar 18 2017 sql drwxr-xr-x 5 7161 31415 4096 Mar 18 2017 sql-bench drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 sql-common drwxr-xr-x 13 7161 31415 4096 Mar 18 2017 storage drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 strings drwxr-xr-x 5 7161 31415 4096 Mar 18 2017 support-files drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 tests drwxr-xr-x 5 7161 31415 4096 Mar 18 2017 unittest -rw-r--r-- 1 7161 31415 88 Mar 18 2017 VERSION drwxr-xr-x 3 7161 31415 4096 Mar 18 2017 vio drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 win drwxr-xr-x 2 7161 31415 4096 Mar 18 2017 zlib
5、在安装包目录内，编译MySQL软件。

7、确认安装目录是否存在并创建软链接
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# ll /usr/local/ total 52 drwxr-xr-x 5 root root 4096 Feb 3 22:12 aegis drwxr-xr-x. 2 root root 4096 Nov 5 2016 bin drwxr-xr-x 10 root root 4096 Feb 3 22:12 cloudmonitor drwxr-xr-x. 2 root root 4096 Nov 5 2016 etc drwxr-xr-x. 2 root root 4096 Nov 5 2016 games drwxr-xr-x. 2 root root 4096 Nov 5 2016 include drwxr-xr-x. 2 root root 4096 Nov 5 2016 lib drwxr-xr-x. 2 root root 4096 Nov 5 2016 lib64 drwxr-xr-x. 2 root root 4096 Nov 5 2016 libexec drwxr-xr-x 13 root root 4096 Feb 3 22:52 mysql-5.6.36 drwxr-xr-x. 2 root root 4096 Nov 5 2016 sbin drwxr-xr-x. 6 root root 4096 Feb 1 10:38 share drwxr-xr-x. 2 root root 4096 Nov 5 2016 src [root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# ln -s /usr/local/mysql-5.6.36/ /usr/local/mysql [root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# ll /usr/local/ total 52 drwxr-xr-x 5 root root 4096 Feb 3 22:12 aegis drwxr-xr-x. 2 root root 4096 Nov 5 2016 bin drwxr-xr-x 10 root root 4096 Feb 3 22:12 cloudmonitor drwxr-xr-x. 2 root root 4096 Nov 5 2016 etc drwxr-xr-x. 2 root root 4096 Nov 5 2016 games drwxr-xr-x. 2 root root 4096 Nov 5 2016 include drwxr-xr-x. 2 root root 4096 Nov 5 2016 lib drwxr-xr-x. 2 root root 4096 Nov 5 2016 lib64 drwxr-xr-x. 2 root root 4096 Nov 5 2016 libexec lrwxrwxrwx 1 root root 24 Feb 3 22:57 mysql -> /usr/local/mysql-5.6.36/ drwxr-xr-x 13 root root 4096 Feb 3 22:52 mysql-5.6.36 drwxr-xr-x. 2 root root 4096 Nov 5 2016 sbin drwxr-xr-x. 6 root root 4096 Feb 1 10:38 share drwxr-xr-x. 2 root root 4096 Nov 5 2016 src
8、设置MySQL目录属主和属组
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# chown -R mysql.mysql /usr/local/mysql/
9、拷贝MySQL配置文件；如果有提示（cp: overwrite `/etc/my.cnf’?）按“y”确认。
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
10、初始化MySQL软件，指明安装目录、数据库存放位置及授权给mysql用户。PS：看到两个OK就代表没问题
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# /usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --user=mysql Installing MySQL system tables...2018-02-03 23:02:35 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

To do so, start the server, then issue the following commands: /usr/local/mysql//bin/mysqladmin -u root password 'new-password' /usr/local/mysql//bin/mysqladmin -u root -h izuf6in4w20dqvk2nrs45kz password 'new-password' Alternatively you can run: /usr/local/mysql//bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd . ; /usr/local/mysql//bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd mysql-test ; perl mysql-test-run.pl Please report any problems at http://bugs.mysql.com/ The latest information about MySQL is available on the web at http://www.mysql.com Support MySQL by buying support/licenses at http://shop.mysql.com New default config file was created as /usr/local/mysql//my.cnf and will be used by default by the server when you start it. You may edit this file to change server settings WARNING: Default config file /etc/my.cnf exists on the system This file will be read by default by the MySQL server If you do not want to use this, either remove it, or use the --defaults-file argument to mysqld_safe when starting the server
11、拷贝MySQL服务脚本并赋予执行权限
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld && chmod +x /etc/init.d/mysqld
12、配置MySQL环境变量并重载环境变量
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# echo 'export PATH=/usr/local/mysql/bin:$PATH' >>/etc/profile && source /etc/profile
13、将MySQL启动服务加入到系统服务并检查
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# chkconfig --add mysqld
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# chkconfig --list mysqld
Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.
If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
14、启动MySQL软件
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# systemctl start mysqld
15、登录MySQL，此时登录密码为空，直接就可以登录进去。
[root@izuf6in4w20dqvk2nrs45kz mysql-5.6.36]# mysql Welcome to the MySQL monitor. Commands end with ; or \g.

Type '\c' to clear the current input statement. mysql>
初始化：
默认安装后的MySQL用户root为空密码状态，存在匿名用户，存在测试数据库；利用/usr/local/mysql/bin目录下的mysql_secure_installation安全配置向导文件来初始化数据库
[root@izuf6in4w20dqvk2nrs45kz bin]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): <–第一次运行因为用户root为空密码状态所以直接回车即可
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] <– 是否设置root用户密码，默认为“y”直接回车即可。
New password: <– 设置root用户的密码，密码不显示直接输入后回车即可。
Re-enter new password: <– 再输入一次你设置的密码回车即可
Password updated successfully!
Reloading privilege tables..
... Success!
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? [Y/n] <– 是否删除匿名用户,生产环境建议删除，默认为“y”直接回车即可。
... 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? [Y/n] <–是否禁止root远程登录,根据自己的需求选择；禁止的话默认为“y”直接回车即可。
... 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? [Y/n] <– 是否删除test数据库,生产环境建议删除，默认为“y”直接回车即可。
- 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? [Y/n] <– 是否重新加载权限表，默认为“y”直接回车即可。
... Success!
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
Cleaning up...
