坑总结
# 1,当前环境下时候有安装过,先清除
whereis mysql
find /-name mysql
# 2,解压后查看是否有data文件夹,没有新建
mkdir data# 并编辑my.cnf的数据存放路径cat/etc/my.cnf
# database=新建data的路径# 3,配置my.cnf的socket并开发权限# socket=/var/lib/mysql/mysql.sock
cd /var/lib/ls
mkdir mysql
ll
chown mysql mysql
ll
chgrp mysql mysql
ll
# 4,初始化失败./mysqld --initialize --user=mysql --basedir=/usr/local/mysql/mysql-5.7.27 --datadir=/usr/local/mysql/mysql-5.7.27/data# ./mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory# 缺少 libaio.so.1依赖cat/proc/version # 查看是什么系统 Red Hat 使用 yum
yum install libaio
# 再次初始化# --initialize specified but the data directory has files in it. Aborting.# 这时需要清除 data目录下必须是空文件夹 rm 即可# 再次初始化,直到[Note]出密码即可# 5,启服务
service mysql start# 报错:ERROR! The server quit without updating PID file (/usr/local/mysql/mysql-5.7.27/data/sentos.pid).# my.cnf中:log-error=/var/log/mariadb/mariadb.log
mkdir /var/log/mariadb
cd /var/log/mariadb
touch mariadb # 在该路径下创建该文件即可
chown -R mysql:mysql mariadb/# 6,远程连接访问并开放防火墙
mysql -u root -p
use mysql
update user set host='%' where user = 'root'
flush privileges
select host,user from mysql.user
firewall-cmd --list-ports
firewall-cmd --zone=public --add-port=3306/tcp --permanent
firewall-cmd --reload
