Linux MySql5.6.38安装过程

1.下载mysql安装包mysql-5.6.38-linux-glibc2.12-x86_64.tar.gz

2.用xftp工具将其上传到Linux服务器上的soft文件夹，没有的话先创建

[root@master ~]# cd /
[root@master /]# ls
bin dev home lib64 media opt root selinux sys usr
boot etc lib lost+found mnt proc sbin srv tmp var
[root@master /]# mkdir soft

3.解压mysql-5.6.38-linux-glibc2.12-x86_64.tar.gz

[root@master soft]# tar ‐zxvf mysql‐5.6.‐linux‐glibc2.‐x86_64.tar.gz

4.删除mysql-5.6.38-linux-glibc2.12-x86_64.tar.gz并将解压的文件夹重命名为mysql

[root@master soft]# ls
mysql‐5.6.‐linux‐glibc2.‐x86_64 mysql‐5.6.‐linux‐glibc2.‐x86_64.tar.gz
[root@master soft]# rm ‐rf mysql‐5.6.‐linux‐glibc2.‐x86_64.tar.gz
[root@master soft]# mv mysql‐5.6.‐linux‐glibc2.‐x86_64/ mysql

5.查看之前系统是否安装过mysql

[root@master soft]# rpm ‐qa|grep mysql
mysql‐libs‐5.1.‐.el6_6.x86_64

6.卸载之前安装过的mysql

[root@master soft]# rpm ‐e ‐‐nodeps mysql‐libs‐5.1.‐.el6_6.x86_64
[root@master soft]# rpm ‐qa|grep mysql
[root@master soft]#

7.查看系统之前是否有mysql用户

[root@master soft]# groups mysql
groups: mysql：无此用户

8.创建mysql用户组及用户

[root@master soft]# groupadd mysql
[root@master soft]# useradd ‐r ‐g mysql mysql

9.将解压的mysql文件夹移动到/usr/local目录下

[root@master soft]# mv mysql/ /usr/local/

10.进入/usr/local/文件夹并修改mysql文件夹用户组及用户为mysql

[root@master soft]# cd /usr/local/
[root@master local]# chown ‐R mysql:mysql mysql
[root@master local]# ll
总用量
drwxr‐xr‐x.  root root  9月   bin
drwxr‐xr‐x.  root root  9月   etc
drwxr‐xr‐x.  root root  9月   games
drwxr‐xr‐x.  root root  9月   include
drwxr‐xr‐x.  root root  9月   lib
drwxr‐xr‐x.  root root  9月   lib64
drwxr‐xr‐x.  root root  9月   libexec

drwxr‐xr‐x.  root root  9月   sbin
drwxr‐xr‐x.  root root  1月  : share
drwxr‐xr‐x.  root root  9月   src
[root@master local]#

11.修改/etc/hosts文件夹将IP和主机名添加进去

[root@master scripts]# vi /etc/hosts

192.168.1.110 master
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
:: localhost localhost.localdomain localhost6 localhost6.localdomain6

12.进入mysql/scripts/文件夹，进行安装

[root@master scripts]# ./mysql_install_db ‐‐basedir=/usr/local/mysql ‐‐
datadir=/usr/local/mysql/data ‐‐user=mysql ‐‐explicit_defaults_for_timestamp

 To start mysqld at boot time you have to copy
 support‐files/mysql.server to the right place for your system
 PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
 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 master 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

可能出现的错误

、数据初始化‐主机名解析错误
系统‐Red Hat Enterprise Linux Server release 6.6
软件‐源码安装mysql‐5.6..tar.gz
环境‐Linux rhel6.myexample.com 2.6.‐.el6.x86_64 # SMP Tue Sep  :: EDT  x86_64
x86_64 x86_64 GNU/Linux
报错：WARNING
[root@rhel6 mysql]# scripts/mysql_install_db ‐‐user=mysql
WARNING: The host 'rhel6.myexample.com' could not be looked up with ./bin/resolveip.
This probably means that your libc libraries are not  % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !
原因：主机名解析错误。
解决：hosts文件中添加如下内容，ok！
[root@rhel6 mysql]# vi /etc/hosts
192.168.56.20 rhel6.myexample.com
总结：
因为lib库不是很兼容当前MySQL版本。在主机名解析不起作用的情况下，会引起MySQL守护进程、mysqld工作异常，因
此在MySQL中授权时需要使用IP地址，而不能使用主机名。
（不解决该问题，依然可以正确执行scripts/mysql_install_db数据库初始化脚本。）
、数据初始化‐时间戳问题
系统‐Red Hat Enterprise Linux Server release 6.6
软件‐源码安装mysql‐5.6..tar.gz
环境‐Linux rhel6.myexample.com 2.6.‐.el6.x86_64 # SMP Tue Sep  :: EDT  x86_64
x86_64 x86_64 GNU/Linux
报错：Warning
[root@rhel6 mysql]# scripts/mysql_install_db ‐‐user=mysql
Installing MySQL system tables...‐‐ ::  [Warning] TIMESTAMP with implicit DEFAULT
value is deprecated. Please use ‐‐explicit_defaults_for_timestamp server option (see
documentation for more details).
‐‐ ::  [Note] ./bin/mysqld (mysqld 5.6.) starting as process  ...
原因：机器的系统时间与TIMESTAMP时间戳不匹配。
解决：执行mysql_install_db数据初始化脚本时添加explicit_defaults_for_timestamp选项。
[root@rhel6 mysql]# scripts/mysql_install_db ‐‐user=mysql ‐‐explicit_defaults_for_timestamp
、数据初始化‐重复安装引起多个配置文件，默认配置文件
系统‐Red Hat Enterprise Linux Server release 6.6
软件‐源码安装mysql‐5.6..tar.gz
环境‐Linux rhel6.myexample.com 2.6.‐.el6.x86_64 # SMP Tue Sep  :: EDT  x86_64
x86_64 x86_64 GNU/Linux
报错：Warning
WARNING: Found existing config file ./my.cnf on the system.
Because this file might be in use, it was not replaced,
but was used in bootstrap (unless you used ‐‐defaults‐file)
and when you later start the server.
The new default config file was created as ./my‐new.cnf,
please compare it with your file and take the changes you need.
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
原因：
Warning1是因为重复安装，导致在安装目录下已经存在my.cnf文件。
Warning2是指默认的my.cnf配置文件在/etc/目录下。
启动Mysql server时，可指定‐‐default‐file=/path/my.cnf参数来启动mysql服务。

13.返回上一级mysql目录，修改data文件及用户组及用户为mysql

[root@master scripts]# cd ..
[root@master mysql]# chown ‐R mysql:mysql data

14.修改mysql密码，之前安装时已经提示如何修改

/usr/local/mysql/bin/mysqladmin ‐u root password 'new‐password'
/usr/local/mysql/bin/mysqladmin ‐u root ‐h master password 'new‐password'

[root@master bin]# ./mysqladmin ‐u root password 'root'

有可能会出现以下错误

[root@master bin]# ./mysqladmin ‐u root password 'root'
./mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' ()'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
[root@master bin]#

因为这时还没有启动mysql，这算是一个坑。

15.启动mysql，进入mysql/support-files文件夹执行命令

[root@master mysql]# cd support‐files/
[root@master support‐files]# ls
binary‐configure magic my‐default.cnf mysqld_multi.server mysql‐log‐rotate mysql.server
[root@master support‐files]# ./mysql.server start
Starting MySQL.Logging to '/usr/local/mysql/data/master.err'.
SUCCESS!
[root@master support‐files]#

16.在重新执行命令修改密码

[root@master bin]# ./mysqladmin ‐u root password 'root'
Warning: Using a password on the command line interface can be insecure.
[root@master bin]#

17.登录mysql

[root@master bin]# ./mysql ‐uroot ‐p
Enter password:

mysql>

18.将其他用户的密码也修改为root

update mysql.user set password=password('root') where user='root'; flush privileges;

mysql> update mysql.user set password=password('root') where user='root'; flush privileges;
Query OK,  rows affected (0.00 sec)
Rows matched:  Changed:  Warnings:
Query OK,  rows affected (0.00 sec)
mysql>

19.在Windows上远程连接mysql，此时端口不同，关闭Linux上的防火墙

[root@master bin]# service iptables stop
iptables：将链设置为政策 ACCEPT：filter [确定]
iptables：清除防火墙规则： [确定]
iptables：正在卸载模块： [确定]
[root@master bin]#

此时在Windows上用cmd窗口Telnet Linux服务器3306端口报错

D•Host '192.168.1.1' is not allowed to connect to
遗失对主机的连接。
C:\Users\Administrator>telnet 192.168.1.110 

为解决这一问题，需要本地登陆MySQL后执行如下命令

mysql> grant all privileges on *.* to root@'%' identified by 'root';
Query OK,  rows affected (0.00 sec)
mysql> flush privileges;
Query OK,  rows affected (0.00 sec)
mysql>

执行之后即可连接成功

20.将mysql加入services服务

[root@master mysql]# cp support‐files/mysql.server /etc/init.d/mysqld
[root@master mysql]# chkconfig ‐‐add mysqld
[root@master mysql]# chkconfig mysqld on
[root@master mysql]# service mysqld restart
Shutting down MySQL.... SUCCESS!
Starting MySQL. SUCCESS!
[root@master mysql]#

查看状态

[root@master mysql]# service mysqld status
SUCCESS! MySQL running ()
[root@master mysql]#

21.配置my.cnf

[root@master mysql]# vi my.cnf

[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at % of total RAM for dedicated server, else %.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
default‐character‐set=utf8
lower_case_table_names=
max_allowed_packet=100M
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

配置好之后充气mysql服务

[root@master data]# service mysqld restart
ERROR! MySQL server PID file could not be found!
Starting MySQL... ERROR! The server quit without updating PID file
(/usr/local/mysql/data/master.pid).

此时报错，查看/usr/local/mysql/data/master.err文件发现报错内容

‐‐ ::  [ERROR] /usr/local/mysql/bin/mysqld: unknown variable 'defaultcharacter‐
set=utf8'
‐‐ ::  [ERROR] Aborting

my.cnf字符集设置问题，重新设置为character_set_server=utf8

重新启动解决

[root@master mysql]# service mysqld restart
Shutting down MySQL.. SUCCESS!
Starting MySQL. SUCCESS!
[root@master mysql]#
