Centos---MySQL数据库部署_centos部署mysql

一、环境

基于Centos 7.4 系统
查看系统环境：

[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core) 
1
2

安装常用的软件包

yum install -y vim bash-completion lrzsz wget net-tools psmisc tree  dos2unix 
1

系统配置

关闭防火墙
[root@localhost ~]# systemctl stop firewalld
禁用开机自启防火墙
[root@localhost ~]# systemctl disable firewalld
关闭selinux
[root@localhost ~]# setenforce 0
禁用开机自启selinux
[root@localhost ~]# vim /etc/selinux/config
SELINUX=disabled

二、YUM在线安装

下载并安装MySQL的官方yum源
进入官网




下载MySQL Yum Repository

[root@localhost yum.repos.d]# wget -c https://dev.mysql.com/get/mysql80-community-release-el7-5.noarch.rpm
1

安装yum源

[root@localhost ~]# yum localinstall mysql80-community-release-el7-5.noarch.rpm 
1

选择发行版本

	禁用8.0：yum-config-manager --disable mysql80-community
	启用5.7：yum-config-manager --enable mysql57-community	
	该命令在centos默认是没有安装
	下载提供该命令的软件包
	[root@localhost ~]# yum provides */yum-config-manager
	验证
	[root@localhost yum.repos.d]# yum repolist enabled | grep mysql
mysql-connectors-community/x86_64       MySQL Connectors Community           230

首先查看有没有mariadb-libs软件包
[root@localhost ~]# rpm -qa | grep mariadb*
mariadb-libs-5.5.56-2.el7.x86_64
卸载mariadb软件包
[root@localhost ~]# yum remove mariadb-libs.x86_64 
安装：
[root@localhost ~]# rpm -ivh mysql-community-client-5.7.37-1.el7.x86_64.rpm  mysql-community-common-5.7.37-1.el7.x86_64.rpm  mysql-community-libs-5.7.37-1.el7.x86_64.rpm  mysql-community-server-5.7.37-1.el7.x86_64.rpm

四、通用二进制安装

下载glibc版本的MySQL

[root@localhost ~]# wget -c https://repo.huaweicloud.com/mysql/Downloads/MySQL-5.7/37-linux-glibc2.12-x86_64.tar.gz
1

创建用户和组

以RPM方式安装，都会创建用户mysql 
所以二进制安装时需要自己创建mysql 组和用户
[root@localhost ~]# groupadd mysql -r -g 306
（创建系统组，指定组的ID）
[root@localhost ~]# useradd -r -g mysql -s /bin/false -u 306 mysql
（创建系统用户，指定用户的基本组，无权访问系统上交互式shell）

安装并初始化MySQL

解压文件到/usr/local/
[root@localhost ~]# tar xf mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz -C /uar.gz -C /usr/local/
创建软链接-u显示创建的过程
[root@localhost ~]# ln -sv /usr/local/mysql-5.7.37-linux-glibc2.12-x86_64/ /usr/local/mysql
‘/usr/local/mysql’ -> ‘/usr/local/mysql-5.7.37-linux-glibc2.12-x86_64/’
修改/usr/local/mysql目录下所有文件的所属组和所属用户
[root@localhost ~]# chown -R mysql.mysql /usr/local/mysql/*
查看
[root@localhost ~]# ll /usr/local/mysql/
total 272
drwxr-xr-x.  2 mysql mysql   4096 Mar 28 05:02 bin

将MySQL的bin目录加入PATH环境变量，编辑/etc/profile.d/mysql.sh

[root@localhost ~]# vim /etc/profile.d/mysql.sh
添加如下内容：
export PATH=$PATH:/usr/local/mysql/bin
（下次登录有效）
现在立刻生效：
[root@localhost ~]# source /etc/profile.d/mysql.sh

初始化

源码方式需要手工初始化
[root@localhost ~]# mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
（记住临时密码）

为MySQL提供主配置文件

从另一台已经安装好MySQL的linux主机中复制一份配置文件，将文件复制到/etc目录下
[root@localhost ~]# scp 192.168.6.16:/etc/my.cnf /etc
The authenticity of host '192.168.6.16 (192.168.6.16)' can't be established.

修改主配置文件
[root@localhost ~]# vim /etc/my.cnf

为MySQL提供sysv服务脚本

[root@localhost ~]# cp /usr/local/mysql/support-files/mysql.server  /etc/in
it.d/mysqld
查看该文件是否有执行权限
[root@localhost ~]# ll /etc/init.d/mysqld
-rwxr-xr-x. 1 root root 10576 Mar 28 06:35 /etc/init.d/mysqld
若没有：
[root@localhost mysql]# chmod +x /etc/init.d/mysqld

[root@localhost ~]# chkconfig mysqld on
[root@localhost ~]# systemctl start mysqld
查看MySQL状态
[root@localhost ~]# systemctl status mysqld

五、源码安装

下载软件压缩包
网站地址mirrors.huaweicloud.com(使用国内镜像站点下载速度会比官网上下载速度快)

[root@localhost ~]# wget -c https://repo.huaweicloud.com/mysql/Downloads/MySQL-5.7/mysql-boost-5.7.37.tar.gz
1

安装开发工具

[root@localhost ~]# yum install make gcc gcc-c++ cmake bison-devel ncurses-devel -y
1

解压
指定解压路径/usr/local/src/

[root@localhost ~]#tar xf mysql-boost-5.7.37.tar.gz  -C /usr/local/src/
切换到解压路径下
[root@localhost ~]# cd /usr/local/src/mysql-5.7.37/
1

创建用户和组

创建mysql系统组，指定组编号为306
[root@localhost ~]# groupadd -r -g 306 mysql
创建mysql系统用户，指定mysql用户的基本组，用户编号，无权访问系统上交互式shell
[root@localhost ~]# useradd -r -g mysql -u 306 -s /bin/false mysql

使用cmake编译MySQL
(注意：如果详情里此前编译所生成的文件重新编译，需要使用如下两个命令：make clean;rm -f CMakeCache.txt)

cmake -DWITH_BOOST=/usr/local/src/mysql-5.7.37/boost \	
-DWITH_SSL=system \	
-DWITH_ZLIB=system \	
-DSYSCONFDIR=/etc \	
-DMYSQL_DATADIR=/usr/local/mysql/data 
编译后报错
报错原因：
1、缺少openssl-devel
Cannot find appropriate system libraries for WITH_SSL=system.
Make sure you have specified a supported SSL version. 
Valid options are : 
system (use the OS openssl library), 
yes (synonym for system), 
</path/to/custom/openssl/installation>
解决方法：
[root@localhost mysql-5.7.37]# yum install openssl-devel -y
[root@localhost mysql-5.7.37]# make clean
make: *** No rule to make target `clean'.  Stop
[root@localhost mysql-5.7.37]#rm -f CMakeCache.txt 
再次编译：
[root@localhost mysql-5.7.37]#cmake -DWITH_BOOST=/usr/local/src/mysql-5.7.37/boost \	
-DWITH_SSL=system \	
-DWITH_ZLIB=system \	
-DSYSCONFDIR=/etc \	
-DMYSQL_DATADIR=/usr/local/mysql/data  
编译安装
[root@localhost mysql-5.7.14]# make && make install

编辑文件立刻生效
[root@localhost mysql-5.7.37]# source /etc/profile.d/mysql.sh

为MySQL提供主配置文件

从以安装MySQL的linux主机上复制一份配置文件到etc目录下
[root@localhost ~]# scp 192.168.6.14:/etc/my.cnf  /etc
编辑配置为文件
[root@localhost ~]# vim /etc/my.cnf
