MySQL8.0的安装及配置

环境：centos7 64位

1.修改镜像源

1. 备份yum源源文件

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

2. 修改yum源文件：使用阿里云的yum源文件

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

3. 清理缓存

yum clean all
yum makecache

2.安装MySQL源

1. 执行# wget http://dev.mysql.com/get/mysql80-community-release-el7-8.noarch.rpm将MySQL的rpm包下载到当前工作目录下

[root@localhost software]# ls
mysql80-community-release-el7-8.noarch.rpm

2. 安装MySQL的rpm包

yum localinstall -y mysql80-community-release-el7-8.noarch.rpm

3. 查看源是否安装成功

[root@localhost software]# yum repolist enabled | grep mysql
mysql-connectors-community/x86_64 MySQL Connectors Community                 242
mysql-tools-community/x86_64      MySQL Tools Community                      104
mysql80-community/x86_64          MySQL 8.0 Community Server                 465

3.安装MySQL

1. 使用yum -y install mysql-community-server --nogpgcheck安装
2. 安装完毕后，使用以下命令查看安装的MySQL包信息

[root@localhost software]# rpm -qa |grep mysql
mysql80-community-release-el7-8.noarch
mysql-community-client-plugins-8.0.36-1.el7.x86_64
mysql-community-icu-data-files-8.0.36-1.el7.x86_64
mysql-community-common-8.0.36-1.el7.x86_64
mysql-community-libs-8.0.36-1.el7.x86_64
mysql-community-libs-compat-8.0.36-1.el7.x86_64
mysql-community-client-8.0.36-1.el7.x86_64
mysql-community-server-8.0.36-1.el7.x86_64

3. 一些项目开发中经常使用到MySQL开发包，这里安装

yum install mysql-devel --nogpgcheck

4.MySQL的基本配置

1. 查看默认密码

[root@localhost software]#  cat /var/log/mysqld.log | grep password
2024-04-28T13:57:06.274192Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: CQlhhk.?y4;r

2. 修改密码：先使用默认密码连接上MySQL server，然后更改

mysql -u root -p
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

3. 防火墙配置开启3306端口
   1. 修改配置

   firewall-cmd --zone=public --add-port=3306/tcp --permanent
   

   2. 重新加载配置

   firewall-cmd --reload
   

cgdb的安装

1. 下载源码：wget https://github.com/cgdb/cgdb/archive/v0.7.0.tar.gz
2. 解压：

tar -zxvf v0.7.0.tar.gz
cd cgdb-0.7.0/

3. 安装automake工具

yum install automake

4. 执行脚本：./autogen.sh
5. 安装flex/ncurses-devel/texinfo/ readline-devel等

yum install ncurses-devel
yum install flex
yum install texinfo
yum install  readline-devel

6. 执行 ./configure
7. 编译/安装

make -j 2 && make install
