主機安裝[容器]部分可忽略
創建容器[容器]
docker run -itd --name mycat --privileged=true centos:7.9.2009 /usr/sbin/init
docker exec -it 26a7b7740b39 /bin/bash
準備工作
安裝java[容器]
yum install java
[root@574ab73efc24 /]# java -version
openjdk version "1.8.0_332"
OpenJDK Runtime Environment (build 1.8.0_332-b09)
OpenJDK 64-Bit Server VM (build 25.332-b09, mixed mode)
安裝wget[容器]
yum -y install wget
安裝vim[容器]
yum -y install vim
卸載MariaDB
# 查看版本：
[root@localhost opt]# rpm -qa|grep mariadb
mariadb-libs-5.5.68-1.el7.x86_64
# 卸載
[root@localhost opt]# rpm -e --nodeps mariadb-libs-5.5.68-1.el7.x86_64
# 檢查是否卸載干凈
rpm -qa|grep mariadb
卸載舊的mysql
rpm -qa | grep mysql
[root@localhost opt]# rpm -qa | grep mysql
mysql80-community-release-el8-4.noarch
[root@localhost opt]# yum remove mysql80-community-release-el8-4.noarch
[root@localhost opt]# find / -name mysql
/etc/selinux/targeted/active/modules/100/mysql
/usr/lib64/mysql
/usr/share/mysql
[root@localhost opt]# rm -rf /etc/selinux/targeted/active/modules/100/mysql
[root@localhost opt]# rm -rf /usr/lib64/mysql
[root@localhost opt]# rm -rf /usr/share/mysql
[root@localhost opt]# rpm -pa | grep mariadb
源碼安裝
下載mysql
加速站
yum update ca-certificates -y
wget https://mirrors.tuna.tsinghua.edu.cn/mysql/downloads/MySQL-8.0/mysql-8.0.29-el7-x86_64.tar
tar -xvf mysql-8.0.29-el7-x86_64.tar
tar -zxvf mysql-8.0.29-el7-x86_64.tar.gz
mv mysql-8.0.29-el7-x86_64 mysql
mv mysql /usr/local/
cd /usr/local/mysql
mkdir mysqldb
mysql安裝目錄賦予權限
chmod -R 777 /usr/local/mysql
創建組
[root@localhost mysql]# pwd
/usr/local/mysql
groupadd mysql
創建用戶(-s /bin/false參數指定mysql用戶僅擁有所有權，而沒有登錄權限)
useradd -r -g mysql -s /bin/false mysql
將用戶添加到組中
chown -R mysql:mysql ./
解決中文亂碼[容器]
[root@a8fedf6f30e8 mysql]# export LANG=en_ZW.utf8
[root@a8fedf6f30e8 mysql]# source /etc/profile
[root@a8fedf6f30e8 mysql]# vim /etc/profile
LANG=en_ZW.utf8
[root@a8fedf6f30e8 mysql]# source /etc/profile
修改mysql配置文件 vi /etc/my.cnf
[mysqld]
# 設置3306端口
port=3306
# 設置mysql的安裝目錄
basedir=/usr/local/mysql
# 設置mysql數據庫的數據的存放目錄
datadir=/usr/local/mysql/mysqldb
# 允許最大連接數
max_connections=10000
# 允許連接失敗的次數。這是為了防止有人從該主機試圖攻擊數據庫系統
max_connect_errors=10
# 服務端使用的字符集默認為UTF8
character-set-server=utf8
# 創建新表時將使用的默認存儲引擎
default-storage-engine=INNODB
# 默認使用“mysql_native_password”插件認證
default_authentication_plugin=mysql_native_password
[mysql]
# 設置mysql客戶端默認字符集
default-character-set=utf8
[client]
# 設置mysql客戶端連接服務端時默認使用的端口
port=3306
default-character-set=utf8
安裝依賴庫libaio[容器]
yum install -y libaio
yum -y install numactl.x86_64
rpm -qa|grep libaio
安裝mysql
cd /usr/local/mysql/bin/
./mysqld --initialize --console
密碼:S)oBeoS;q6LV
2022-07-02T09:04:18.017337Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: S)oBeoS;q6LV
啟動mysql服務
cd /usr/local/mysql/support-files
chmod -R 777 /usr/local/mysql
./mysql.server start
將mysql添加到系統進程中
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
此時我們就可以使用服務進程操作mysql了
設置mysql自啟動
chmod +x /etc/init.d/mysqld
systemctl enable mysqld
[root@localhost support-files]# chmod +x /etc/init.d/mysqld
[root@localhost support-files]# systemctl enable mysqld
mysqld.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig mysqld on
設置環境變量
vim /etc/profile
MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin
source /etc/profile
修改root用戶登錄密碼
登錄mysql
cd /usr/local/mysql/bin/
./mysql -u root -p
mysql> alter user 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
設置允許遠程登錄
mysql> use mysql
mysql> update user set user.Host='%'where user.User='root';
mysql> flush privileges;
mysql> quit
重啟服務且測試
systemctl restart mysql
systemctl status mysql
查看防火墻開放端口
firewall-cmd --list-all
在防火墻中將3306端口開放
firewall-cmd --zone=public --add-port=3306/tcp --permanent
firewall-cmd --reload
//--permanent為永久生效，沒有此參數 服務器重啟后配置失效
# 關閉防火墻
systemctl stop firewalld.service
# 查看防火墻狀態
firewall-cmd --state
