mysql8.0.16二进制安装
环境简介
操作系统：Centos 6.10 64位目前版本：8.0.16 MySQL Community Server 二进制
目的：升级为8.0.16
安装目录:/data/mysql/mysql_3306
# 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
cat >>/etc/sysctl.conf <<"EOF"vm.swappiness=0#增加tcp支持的队列数net.ipv4.tcp_max_syn_backlog = 65535#减少断开连接时 ，资源回收net.ipv4.tcp_max_tw_buckets = 8000net.ipv4.tcp_tw_reuse = 1net.ipv4.tcp_tw_recycle = 1net.ipv4.tcp_fin_timeout = 10#改变本地的端口范围net.ipv4.ip_local_port_range = 1024 65535#允许更多的连接进入队列net.ipv4.tcp_max_syn_backlog = 4096 #对于只在本地使用的数据库服务器net.ipv4.tcp_fin_timeout = 30#端口监听队列net.core.somaxconn=65535#接受数据的速率net.core.netdev_max_backlog=65535net.core.wmem_default=87380net.core.wmem_max=16777216net.core.rmem_default=87380net.core.rmem_max=16777216EOFsysctl -p
# 第二部分：mysql的安装配置
# 1、下载安装包# 社区版 8.0.16cd /opt/wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.16-linux-glibc2.12-x86_64.tar.xz
# 2、解压安装包
tar -xJf mysql-8.0.16-linux-glibc2.12-x86_64.tar.xz
# 3、进入目录，做软连接，方便以后升级
cd /usr/local/ln -s /opt/mysql-8.0.16-linux-glibc2.12-x86_64 mysql
# 4、创建用户
groupadd mysqluseradd -g mysql mysql -d /home/mysql -s /sbin/nologin
# 5、创建相应的目录
mkdir -p /data/mysql/mysql_3306/{data,logs,tmp,undolog} # 6、创建配置文件
# 排除干扰因素
