centos7 mysql 8.0.13安装完整版

第一步下载

https://dev.mysql.com/downloads/mysql/

第二步上传到服务器

tar -zxvf mysql-8.0.13-el7-x86_64.tar.gz

cd mysql-8.0.13-el7-x86_64

mv mysql-8.0.13-el7-x86_64 mysql8.0.13_x64

第三步创建 mysql 用户组和 mysql 用户

groupadd mysql

useradd -g mysql mysql

第四步改变 mysql 目录权限

chown -R mysql.mysql /usr/local/ mysql8.0.13_x64/

第五步 mysql配置

[mysql]

default-character-set=utf8mb4

socket=/var/lib/mysql/mysql.sock



[client]

default-character-set=utf8mb4

socket=/var/lib/mysql/mysql.sock



[mysqld]

user=mysql

skip-name-resolve

server-id=1

port=3306

lower_case_table_names=1

socket=/var/lib/mysql/mysql.sock

basedir=/usr/local/mysql-8.0.13_x64

datadir=/usr/local/mysql-8.0.13_x64/data

max_connections=800

character-set-server=utf8mb4

default-storage-engine=INNODB

max_allowed_packet=16M

innodb_buffer_pool_size=1G

innodb_flush_log_at_trx_commit=2

binlog_format=MIXED

log-bin=/usr/local/mysql-8.0.13_x64/logs/binlog/mysql-log

binlog-ignore-db=mysql

default_authentication_plugin=mysql_native_password

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

第六步执行 ./mysqld –initialize-insecure 默认空密码

出现以下错误

需要安装 libnuma

yum install libnuma

yum -y install  numactl

yum install libaio1 libaio-dev

./mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

第七步建立MySQL服务

cp -a ./support-files/mysql.server /etc/init.d/mysqld  chmod +x /etc/rc.d/init.d/mysqld      chkconfig --add mysqld

可以检查一下服务是否生效

chkconfig  --list

第八步配置全局环境

vi /etc/profileexport MYSQL_HOME=/usr/local/mysql-8.0.13_x64

PATH=$MYSQL_HOME/bin:$PATH

export PATH

保存退出,使环境变量生效

source /etc/profile

第九步启动mysql服务,关闭和重启

service mysqld startservice mysqld stop service mysqld  restart

第十步

修改密码

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密码'; 

mysql>update user set host='%' where user='root' limit 1;

// 刷新权限

 mysql>flush privileges;

然后检查3306端口是否开放

netstat -nupl|grep 3306

开放3306端口

firewall -cmd --permanent --add-prot=3306/tcp

重启防火墙

firewall -cmd --reload

错误一

把share/english下面的errmsg.sys复制到share目录下面
