mysql在linux上的安装

一、mysql在linux上的安装（yum源安装）

https://blog.csdn.net/huyangg/article/details/71308147

二、mysql在linux上的安装（二进制安装）

说明：在centos7上安装mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz

1）下载mysql的安装包

官方网站下载

百度云下载

2）检查centos7上的maridb，并将器删除

#查找rpm安装的mariadb的安装包的位置
rpm -qa | grep mariadb
-------------------------------
#查找到显示的信息
rpm -qa | grep mariadb
-------------------------------
#卸载上面的包
yum -y remove mariadb-libs-5.5.56-2.el7.x86_64

3）安装包上传和解压

#在/home/weiwei下创建tools和source文件夹，前面的安装软件，后面的上传文件
cd /home/weiwei
mkdir ./tools ./source
#进入上传文件夹的目录下
cd source
rz 点击上传文件
#如果点击rz没有弹框出来，证明没有安装lrzsz，用下面的命令来安装
yum -y install lrzsz
#上传完成之后，将文件解压
tar -zxvf 
#在tools中创建安装mysql的文件夹
cd ../tools
mkdir mysql-5.6.39
#将解压的文件复制到该文件夹下面
cp -r /home/weiwei/source/mysql-5.6.39-linux-glibc2.12-x86_64 /home/weiwei/tools/mysql-5.6.39

4）添加用户组合用户

#执行以下命令来创建mysql用户组
groupadd mysql
#执行以下命令来创建一个用户名为mysql的用户并加入mysql用户组
useradd -g mysql mysql

5）在etc配置mysql的配置文件，其中有mysql的配置的参数，其中mysql的配置参数文件有5个文件几个，名称一样

路径	说明
/etc/my.cnf
basedir/my.cnf
datadir/my.cnf
--defaults-extra-file	#在读取全局配置文件之后，读取用户配置文件(~/.my.cnf)之前，读取extra指定的参数文件
~/.my.cnf	家目录下面的隐藏文件，my.cnf前面的点，说明my.cnf是隐藏文件

注意：假设4个配置文件都存在，同时使用--defaults-extra-file指定了参数文件，如果这时有一个 "参数变量"在5个配置文件中都出现了，那么后面的配置文件中的参数变量值会覆盖前面配置文件中的参数变量值，就是说会使用~/.my.cnf中设置的值。

在/etc下创建文件my.cnf或者直接将mysql文件下support-files/my-default.cnf复制过去，并该名称

#将mysql提供的参考文件拷贝过去，修改名称
cp /home/weiwei/tools/mysql-5.6.39/support-files/my-default.cnf /etc/my.cnf
#修改已过去的配置文件
vim /etc/my.cnf

[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8 
socket=/var/lib/mysql/mysql.sock
 
[mysqld]
skip-name-resolve
#设置3306端口
port = 3306 
socket=/var/lib/mysql/mysql.sock
# 设置mysql的安装目录
basedir=/home/weiwei/tools/mysql-5.6.39
# 设置mysql数据库的数据的存放目录
datadir=/home/weiwei/tools/mysql-5.6.39/data
# 允许最大连接数
max_connections=200
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
lower_case_table_name=1
max_allowed_packet=16M

6）安装

错误一：缺少包

mysqld系统服务配置

三、mysql在linux上的安装（源码编译安装）

说明：部署环境

操作系统： CentOS7

MySQL 版本： mysql-5.6.26.tar.gz

1）源码安装包下载

官网地址

百度云下载地址

1、配置网络
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
HWADDR=00:50:56:a1:12:53
IPADDR=192.168.1.205
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=223.5.5.5
DNS2=223.6.6.6
2、设置主机名
# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=edu-mysql-01
3、设置 IP 与主机名的映射
# vi /etc/hosts
127.0.0.1 edu-mysql-01
192.168.1.205 edu-mysql-01
4、两台数据库服务器的的 selinux 都要 disable
（永久关闭 selinux，请修改/etc/selinux/config，将 SELINUX 改为 disabled）
# vi /etc/selinux/config
SELINUX=disabled
5、重启操作系统
# reboot

2）检查系统是否安装mysql

#检查是否用mysql
rpm -qa | grep mysql
#检查是否用mariadb，一般在centos7都会安装mariadb
rpm -qa | grep mariadb
----------------------------------------
mariadb-libs-5.5.41-2.el7_0.x86_64
----------------------------------------
#因为没有 MySQL 服务，因此没必要卸载。也可以卸载
rpm -e --nodeps mariadb-libs-5.5.41-2.el7_0.x86_64
#或者用下面的命令来进行卸载
yum -y remove mariadb-libs-5.5.41-2.el7_0.x86_64

3）新增用户和用户组

#新增mysql用户组：
groupadd mysql
#新增mysql用户，并添加到mysql用户组：
useradd -r -g mysql mysql

4）建立数据库的数据文件、日志文件、临时文件

#新建MySQL执行文件目录(后面会把编译好的mysql程序安装到这个目录
mkdir -p /usr/local/mysql
#-p参数的作用：如果最终目录的父目录不存在也会一并创建
#新建 MySQL 数据库数据文件目录：
mkdir -p /home/mysql/data
mkdir -p /home/mysql/logs
mkdir -p /home/mysql/temp
#注意：上面的logs及temp目录是为了以后将MySQL的数据文件与执行程序文件分离，如果你打算设置到不同的路径，注意修改对应的执行命令和数据库初始化脚本。
# 正式生产环境，建议数据目录和日志目录都使用单独的分区来挂载， 不同分区属于不同的磁盘或磁盘组。

5）增加path路径

#增加 PATH 环境变量搜索路径：
vi /etc/profile
#在profile文件末尾增加两行
----------------------------------------
#mysql env param
PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
export PATH
----------------------------------------
#使PATH搜索路径立即生效
source /etc/profile

6）安装源码编译需要的包

#安装编译 MySQL 需要的依赖包：
#mysql 从 5.5 版本开始，不再使用./configure 编译，而是使用 cmake 编译器，
#具体的cmake 编译参数可以参考 mysql 官网文档http://dev.mysql.com/doc/refman/5.5/en/source-configuration-options.html，
#安装基本依赖包，先用 yum 安装 cmake、 automake 、 autoconf ，另 MySQL 5.5.x 需要最少安装的包有： bison,gcc、 gcc-c++、 ncurses-devel
yum install make cmake gcc gcc-c++ bison bison-devel ncurses ncurses-devel autoconf automake

7）上传文件

3）

./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/wei/tools/mysql/data

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 localhost 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

----------------------------------------------------------------------------------

一、服务器配置：

1、使用下面的命令检查是否安装有 MySQL Server:

2、改防火墙设置，打开 3306 端口：
# vi /etc/sysconfig/iptables
增加如下行：
## MySQL
-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
重启防火墙：
# service iptables restart
3、

9、进入/usr/local/src 目录，上传 mysql-5.6.26.tar.gz 源代码到/usr/local/src 目录：
# cd /usr/local/src
10、开始编译安装 mysql-5.6.26：
解压缩源码包：
# tar -zxvf mysql-5.6.26.tar.gz
进入解压缩源码目录：
# cd mysql-5.6.26
使用 cmake 源码安装 mysql（如果你打算安装到不同的路径，注意修改下面语句中
/usr/local/mysql 和/home/mysql/data 路径！）
[root@edu-mysql-01 mysql-5.6.26]# cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/home/mysql/data \
-DMYSQL_USER=mysql \
-DMYSQL_TCP_PORT=3306 \
-DENABLE_DOWNLOADS=1
上面的这些复制完，回车，然后就开始 cmake 的过程，一般时间不会很长。

配置解释：
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql 设置安装目录
-DMYSQL_DATADIR=/home/mysql/data 设置数据库存放目录
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock 设置 UNIX socket 目录
-DMYSQL_USER=mysql 设置运行用户
-DDEFAULT_CHARSET=utf8 设置默认字符集，默认 latin1
-DEFAULT_COLLATION=utf8_general_ci 设置默认校对规则，默认 latin1_general_ci
-DWITH_INNOBASE_STORAGE_ENGINE=1 添加 InnoDB 引擎支持
-DENABLE_DOWNLOADS=1 自动下载可选文件，比如自动下载谷歌的测试包
-DMYSQL_TCP_PORT=3306 设置服务器监听端口，默认 3306
-DSYSCONFDIR=/etc 设置 my.cnf 所在目录，默认为安装目录）
执行过程中会出现：
CMake Error: Problem with tar_extract_all(): Invalid argument
CMake Error: Problem extracting tar: /usr/local/src/mysql-5.6.26/source_downloads/gmock-
1.6.0.zip
解决方法：
cd mysql 目录下面会发现有一个 source_downloads 目录，需要解压 unzip gmock-1.6.0.zip,然
后再重新执行上述配置过程。当然你也可以去掉-DENABLE_DOWNLOADS=1 这个选项，不编
译谷歌的测试包也没有什么问题，但是之前的某些版本会出现无法编译的问题.
11、 cmake 结束后开始编译源码，这一步时间会较长，请耐心等待：
# make
12、安装编译好的程序：
# make install
（注意：如果需要重装 mysql，在/usr/local/src/mysql-5.6.26 在执行下 make install 就可以了，
不需要再 cmake 和 make）
13、清除安装临时文件：
# make clean
14、修改 mysql 目录拥有者为 mysql 用户：
# chown -Rf mysql:mysql /usr/local/mysql
# chown -Rf mysql:mysql /home/mysql
15、进入 mysql 执行程序的安装路径：
# cd /usr/local/mysql
16、执行初始化配置脚本，创建系统自带的数据库和表（注意：路径/home/mysql/data 需要
换成你自定定义的数据库存放路径）：
# scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/mysql/data

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 edu-mysql-02 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/

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
17、初始化脚本在/usr/local/mysql/下生成了配置文件 my.cnf，需要更改该配置文件的所有者：
# ls -lah
[root@edu-mysql-01 mysql] # chown -Rf mysql:mysql /usr/local/mysql/my.cnf
18、注意：
（1） Tips：在启动 MySQL 服务时，会按照一定次序搜索 my.cnf，先在/etc 目录下找，找不
到则会搜索 mysql 程序目录下是否有 my.cnf
（2）需要注意 CentOS 6 版操作系统的最小安装完成后，即使没有安装 mysql，在/etc 目录
下也会存在一个 my.cnf 文件，建议将此文件更名为其他的名字，否则该文件会干扰源码安
装的 MySQL 的正确配置，造成无法启动。修改/etc/my.cnf 操作如下：
可以： mv /etc/my.cnf /etc/my.cnf.bak
也可以：删除掉/etc/my.cnf 这个文件： rm /etc/my.cnf
如果你需要用于生产环境，不要急着做下面的 mysql 启动操作。建议把上一步骤中 mysql 初

22、设置 MySQL 开机自动启动服务：
# chkconfig mysql on
设置 MySQL 数据库 root 用户的本地登录密码（初始用户没有密码）：
# mysqladmin -u root password 'roncoo'
23、登录并修改 MySQL 用户 root 的密码：
# mysql -uroot -p
Enter password:

24、运行安全设置脚本，强烈建议生产服务器使用（可选）：
[root@edu-mysql-01 ~]# /usr/local/mysql/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): ----->此处输入 root 密码
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.
Change the root password? [Y/n] n -----> 上已为 root 设置了密码，此处可输 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? [Y/n] Y ------> 删除匿名用户
... 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? [Y/n] n -----> 一般不允许 root 远程登录，可添加普通用户，
然后设置允许远程登录
... 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? [Y/n] Y -----> 删除 test 库及相应权限
- 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] Y -----> 重新加载权限表使设置生效
... 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...
25、重启服务器，检测 mysql 是否能开机自动启动：
[root@edu-mysql-01 ~] # reboot
