準備
- 檢視Linux系統的glibc執行使用的C語言庫版本資訊
[root@lab10 ~]# getconf GNU_LIBC_VERSION
glibc 2.17
[root@lab10 ~]# ldd --version
ldd (GNU libc) 2.17

[root@mysql ~]# rpm -qa | grep glibc
glibc-common-2.17-317.el7.x86_64
glibc-headers-2.17-317.el7.x86_64
glibc-devel-2.17-317.el7.x86_64
glibc-2.17-317.el7.x86_64
compat-glibc-2.12-4.el7.centos.x86_64
compat-glibc-headers-2.12-4.el7.centos.x86_64
- 檢視作業系統的版本資訊
[root@lab10 ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
- 檢視作業系統的網路卡地址
[root@lab10 ~]# ip address show ens32
2: ens32: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 00:0c:29:ec:f2:1b brd ff:ff:ff:ff:ff:ff
inet 10.1.1.10/24 brd 10.1.1.255 scope global ens32
valid_lft forever preferred_lft forever
inet6 fe80::20c:29ff:feec:f21b/64 scope link
valid_lft forever preferred_lft forever
- 檢視系統本地域名解析資訊
[root@lab10 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
- 檢視防火牆服務是否關閉
[root@lab10 ~]# getenforce
Permissive
- 清除系統自帶的mariadb資料庫服務相關的程式包
[root@lab10 ~]# rpm -qa|grep mariadb
mariadb-libs-5.5.68-1.el7.x86_64
[root@lab10 ~]# yum remove -y mariadb-libs
- 安裝資料庫服務程式所需的依賴軟體包
yum install -y libaio-devel
- 需要修改連結庫資訊(只有
centos 8
系統才需要進行操作修改)
[root@xiaoQ-01 ~]# ln -s /usr/lib64/libncurses.so.6 /usr/lib64/libncurses.so.5
或者
[root@xiaoQ-01 ~]# yum install ncurses-compat-libs
下載 MySQL
訪問頁面:MySQL Product Archives
Product Version:
8.2.0
Operating System:Linux - Generic
OS Version:Linux - Generic (glibc 2.17) (ARM, 64-bit)
選擇Compressed TAR Archive
下載
下載連結如下:https://downloads.mysql.com/archives/get/p/23/file/mysql-8.2.0-linux-glibc2.17-x86_64.tar.xz
檔案全稱:mysql-8.2.0-linux-glibc2.17-x86_64.tar.xz
檔案md5:5e37b5f8988d2bc0bfabc39f5b7f9a08
建立MySQL的原始碼目錄
mkdir -p /opt/mysql
上傳 MySQL
使用工具上傳 MySQL
或者
wget https://downloads.mysql.com/archives/get/p/23/file/mysql-8.2.0-linux-glibc2.17-x86_64.tar.xz
進入mysql原始碼目錄
cd /opt/mysql
解壓
tar -xvf mysql-8.2.0-linux-glibc2.17-x86_64.tar.xz
遷移mysql工作目錄
mv mysql-8.2.0-linux-glibc2.17-x86_64 /usr/local/mysql
配置資料庫服務程式環境變數
[root@lab10 ~]# tail -1 /etc/profile
export PATH=/usr/local/mysql/bin:$PATH
[root@lab10 ~]# source /etc/profile
可以獲取資料庫服務版本資訊表示環境變數配置生效
[root@lab10 mysql]# mysql -V
mysql Ver 8.2.0 for Linux on x86_64 (MySQL Community Server - GPL)
建立資料庫服務管理使用者資訊
useradd -r -s /sbin/nologin mysql
建立一個資料庫專用賬號mysql(其所屬組也為mysql)
資料庫初始化操作
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql &> /root/mysql_init_password.txt
/usr/local/mysql/bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data
上面的操作為設定安全加密連線(SSL),資料傳輸會採用加密形式,適合敏感資料
MySQL 的 mysql_ssl_rsa_setup 命令已經被棄用,並將在未來的版本中被移除的警告。告警如下
WARNING: mysql_ssl_rsa_setup is deprecated and will be removed in a future version. Use the mysqld server instead.
MySQL 8.0 以後的版本預設會在伺服器啟動時自動生成 SSL 和 RSA 檔案,所以 mysql_ssl_rsa_setup 命令不再需要。如果你的 MySQL 版本是 8.0 或更高,你可以直接忽略這個警告。
複製mysql指令碼
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
編輯mysqld
vi /etc/init.d/mysqld
修改內容如下
# 第46行
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
啟動mysql
service mysqld start
進入mysql工作目錄
cd /usr/local/mysql
建立my.cnf的配置檔案
vim my.cnf
修改內容如下
[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
port=3306
log-error=/usr/local/mysql/data/master.err
log-bin=/usr/local/mysql/data/binlog => 一定要開啟二進位制日誌
server-id=10
character_set_server=utf8mb4 => utf8mb4相當於utf8升級版
配置完成後,重啟mysqld服務
service mysqld restart
chkconfig --add mysqld
chkconfig mysqld on
檢視是否啟動
[root@lab10 mysql]# netstat -ntlp | grep mysql
tcp6 0 0 :::33060 :::* LISTEN 58001/mysqld
tcp6 0 0 :::3306 :::* LISTEN 58001/mysqld
獲取root預設密碼
grep "password" /root/mysql_init_password.txt
內容如下:
2023-09-12T07:56:02.593722Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: kK%N&gY4ro5i
登入MySQL
mysql -uroot -p'kK%N&gY4ro5i'
修改root密碼,此後root的密碼位Flzx3qc@
ALTER user user() identified by 'Flzx3qc@';
flush privileges;
開啟root遠端登入
use mysql;
select host,user,plugin from user;
- 如果是
plugin == caching_sha2_password
ALTER USER 'root'@'localhost' IDENTIFIED WITH sha256_password BY 'Flzx3qc@';
update user set host = '%' where user = 'root';
flush privileges;
- 如果是
plugin == sha256_password
update user set host = '%' where user = 'root';
flush privileges;
檢視版本資訊與編碼格式
mysql> select version();
+-----------+
| version() |
+-----------+
| 8.0.33 |
+-----------+
1 row in set (0.01 sec)
mysql> show variables like '%character%';
+--------------------------+--------------------------------+
| Variable_name | Value |
+--------------------------+--------------------------------+
| character_set_client | utf8mb4 |
| character_set_connection | utf8mb4 |
| character_set_database | utf8mb4 |
| character_set_filesystem | binary |
| character_set_results | utf8mb4 |
| character_set_server | utf8mb4 |
| character_set_system | utf8mb3 |
| character_sets_dir | /usr/share/mysql-8.0/charsets/ |
+--------------------------+--------------------------------+
8 rows in set (0.01 sec)

使用Navicat連線MySQL

# 資料庫服務初始化經典報錯資訊
報錯情況-01:
[報錯資訊]:
mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
[解決方法]:
yum install -y libaio-devel
報錯情況-02:
[報錯資訊]:
initialize specified but the data directory has files in it. Aborting.
The designated data directory /data/3306/data/ is unusable. You can remove all files that the server added to it.
[解決方法]:
rm -rf /data/3306/data/*
