以下步驟爲安裝 後的總結,可能有些步驟忘記了
下載 mysql 8.0.18 以及解壓
# 下載 mysql 8.0.18
wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz
# mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz 轉換成 mysql-8.0.18-linux-glibc2.12-x86_64.tar
xz -d mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz
# 解壓 mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz
tar -xvf mysql-8.0.18-linux-glibc2.12-x86_64.tar
# mv
mv mysql-8.0.18-linux-glibc2.12-x86_64 mysql
安裝 mysql 3306
# 複製 mysql
cp mysql /user/local/mysql
# 進入/usr/local/mysql目錄
cd /usr/local/mysql
# 檢查mysql組和用戶是否存在
cat /etc/group | grep mysql
cat /etc/passwd | grep mysql
# mysql組和mysql用戶
# useradd -r參數表示mysql用戶是系統用戶，不可用於登錄系統
groupadd mysql
useradd -r -g mysql mysql
# 創建data目錄
mkdir data
# 將/usr/local/mysql的所有者及所屬組改爲mysql
chown -R mysql.mysql /usr/local/mysql
# 創建 my.cnf
vim /etc/my.cnf
# 輸入 如下內容
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
# 忽略表名大消息

# 初始化 mysqld
./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --defaults-file=/etc/my.cnf
# 查看日誌 查找初始密碼
# A temporary password is generated for root@localhost:

# 啓動mysql服務
./support-files/mysql.server start
# 登錄mysql，密碼爲初始密碼 初始密碼在/usr/local/mysql/data/mysqld.log文件中
./mysql -P 3306 -S /tmp/mysql.sock -u root -p
# 修改密碼
alter user 'root'@'localhost' IDENTIFIED BY 'zfs199528';
# 添加遠程訪問權限
use mysql;
