Linux Mysql 8.0.1
下載相應的mysql安裝包後
cp /home/hdkg/soft/mysql-8.0.11-linux-glibc2.12-x86_64.tar/usr/local/
tar xvf mysql-8.0.11-linux-glibc2.12-x86_64.tar
tar zxvf mysql-8.0.11-linux-glibc2.12-x86_64.tar.gz
mv mysql-8.0.11-linux-glibc2.12-x86_64mysql
新增使用者和組
groupadd mysql
useradd -g mysql mysql
cd /usr/local/mysql/
mkdir /data/
chown -R mysql:mysql .
cp /home/hdkg/soft/my.cnf /etc/my.cnf
如果/etc/my.cnf之前存在，就不拷貝了，沒有就自己建立一個吧 ，修改其中
[mysqld]
lower_case_table_names=1
event_scheduler=1
max_connections=500
Datadir=/usr/local/mysql/data
Basedir=/usr/local/mysql
socket = /usr/local/mysql/data/mysql.sock
[client]
socket = /usr/local/mysql/data/mysql.sock
儲存my.cnf
/bin/mysqld--defaults-file=/etc/my.cnf –initialize
有初始化密碼或者
/bin/mysqld--defaults-file=/etc/my.cnf --initialize-insecure 無初始密碼建議這個
我們執行下面這個沒有初始密碼的
bin/mysqld --initialize-insecure --user=mysql--basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
然後
bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data
然後
Cp -r /bin/support-files/mysql.server /etc/init.d/mysqld
然後
service mysqld start
然後
service mysqld status
然後
vi /etc/profile
前面追加客戶端的位置
export PATH=/usr/local/mysql/bin:$PATH
然後
source /etc/profile
然後
mysql -uroot -p 回車
根據前面的操作，有密碼輸入密碼，沒有直接回車
11配置mysql自動啟動
# chmod 755 /etc/init.d/mysqld
# chkconfig --add mysqld
# chkconfig --level 345 mysqld on
建立使用者及修改 root使用者許可權：
use mysql;
CREATE USER 'test'@'%' IDENTIFIEDWITH mysql_native_password BY 'test2007';
flush privileges;
grant all on *.* to 'test'@'%' WITH GRANT OPTION;
flush privileges;
alter user 'root'@'localhost' identified with mysql_native_password by'root';
flush privileges;
update user set host=’%’where user=’root’;
flush privileges’
下面是my.cnf檔案 樣例 紅色部分引數是為了解決，客戶端還停留在5.6.x-5.7.x版本 密碼驗證的問題。還有字符集的問題。
my.cnf 檔案基本內容(紅色部分為要新增部分)

解決客戶端沒有8.0 加密外掛方案

可以通過設定GREP_OPTIONS 為'--color=auto'來自動為匹配部分著色也可以通過設定GREP_COLOR的值來指定顏色下面是部分顏色的值
