linux centos8 安裝mysql8
1 安裝mysql
1 .1 線上下載
wgethttps://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.20-linux-glibc2.12-x86_64.tar.xzz
1 .2 解壓檔案
xz -d mysql-8.0.20-linux-glibc2.12-x86_64.tar.xz
tar xvf mysql-8.0.20-linux-glibc2.12-x86_64.tar
1 .3 移動壓縮包到usr/local目錄下,並重命名檔案
mv /root/mysql-8.0.11-linux-glibc2.12-i686 /usr/local/mysql
1 .4 在
mkdir data
1 .5 建立 mysql 使用者組和 mysql 使用者
groupadd mysql
useradd -g mysql mysql
1 .6 改變 mysql 目錄許可權
chown -R mysql.mysql /usr/local/mysql/
或者
chown -R mysql .
chgrp -R mysql
1 .7 編輯my.cnf檔案
vim /etc/my.cnf
按 i 進入修改模式 然後將下面的文字複製進去
[mysqld]
user=root
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
port=3306
max_connections=200
max_connect_errors=10
character-set-server=utf8
default-storage-engine=INNODB
default_authentication_plugin=mysql_native_password
lower_case_table_names=1
group_concat_max_len=102400
[mysql]
default-character-set=utf8
[client]
port=3306
default-character-set=utf8
1 .8 初始化資料庫
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data //初始化資料庫
或者
/usr/local/mysql/bin/mysqld --initialize --user=mysq
/usr/local/mysql/bin/mysqld --initialize --user=mysql
/usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server in progress as process 5826
[Server] A temporary password is generated for root@localhost: twi=Tlsi<0O!
/usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server has completed
記錄好自己的臨時密碼：
twi=Tlsi<0O!
這裡遇到了問題沒有libnuma.so.1
zsh: command not found: mysqld
./bin/mysqld --initialize
./bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory
2018-04-29 17:06:30 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2018-04-29 17:06:30 [ERROR] Can't locate the language directory.
需要安裝 libnuma
yum install libnuma
yum -y install numactl
yum install libaio1 libaio-dev
安裝檔案
1 .9 mysql配置
cp -a ./support-files/mysql.server /etc/init.d/mysql
chmod +x /etc/init.d/mysql
新增到系統服務
chkconfig --add mysql
檢查服務是否生效
chkconfig --list mysqld
啟動mysql
service mysql start
將mysql新增到命令服務
ln -s /usr/local/mysql/bin/mysql /usr/bin
1 .10 登入MySQL
mysql -uroot -p密碼
如果出現下面報錯
