爱站程序员基地今天有幸尝试安装了社区版本的mysql8.0.15,记录下来，供以后方便使用。特此感谢知数堂的叶金荣，提供了配置文件的模板。
# 第一部分：系统配置
# 1、安装系统依赖包
yum -y install make gcc-c++ cmake bison-devel ncurses-devel readline-devel libaio-devel perl libaio wget lrzsz vim libnuma* bzip2 xz
# 2、关闭selinux
sed -i \'s/SELINUX=enforcing/SELINUX=disabled/\' /etc/selinux/configsetenforce 0
# 3、修改系统限制参数
cat >> /etc/security/limits.conf << EOF####custom#* soft nofile 20480* hard nofile 65535* soft nproc 20480* hard nproc 65535EOF
# 4、修改内核参数

# 7、修改目录权限
chown -R mysql.mysql /data/mysql/mysql_3306
# 8、初始化数据库
# /usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql --initialize-insecure# 官方推荐使用--initialize，会在错误日志中生成难以输入的临时密码，我这里使用的免密码的方式。/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/mysql_3306/my_3306.cnf --initialize-insecure --user=mysql &
# 9、查看日志
# tail -f /data/mysql/mysql_3306/logs/error.log
# 10、启动数据库
/usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysql/mysql_3306/my_3306.cnf &
# 11、首次登录方式
/usr/local/mysql/bin/mysql --socket=/data/mysql/mysql_3306/tmp/mysql_3306.sock
# 12、初次登陆强制修改密码方法

# 13、创建软连接
ln -s /usr/local/mysql/bin/* /usr/bin/ln -s /usr/local/mysql/lib/* /usr/lib64/
