mysql 8.0.18 手工安装记录
为了日常方便，特记录如下。
一、安装系统依赖包
#、系统依赖包安装
yum -y install make gcc-c++ cmake bison-devel ncurses-devel readline-devel libaio-devel perl libaio wget lrzsz vim libnuma* bzip2 xz
二、关闭防火墙和selinux
#、关闭selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
setenforce
#、修改系统限制参数
cat >> /etc/security/limits.conf << EOF
#
###custom
#
* soft nofile
* hard nofile
* soft nproc
* hard nproc
EOF
三、修改系统限制参数
修改系统限制参数
cat >>/etc/sysctl.conf <<"EOF" ##################################
vm.swappiness=
#增加tcp支持的队列数
net.ipv4.tcp_max_syn_backlog =
#减少断开连接时 ，资源回收
net.ipv4.tcp_max_tw_buckets =
net.ipv4.tcp_tw_reuse =
#net.ipv4.tcp_tw_recycle =
net.ipv4.tcp_fin_timeout =
#改变本地的端口范围
net.ipv4.ip_local_port_range =
#允许更多的连接进入队列
net.ipv4.tcp_max_syn_backlog =
#对于只在本地使用的数据库服务器
net.ipv4.tcp_fin_timeout =
#端口监听队列
net.core.somaxconn=
#接受数据的速率
net.core.netdev_max_backlog=
net.core.wmem_default=
net.core.wmem_max=
net.core.rmem_default=
net.core.rmem_max=
EOF sysctl -p
四、修改系统参数限制
# 修改系统限制参数
cat >>/etc/sysctl.conf <<"EOF" ##################################
vm.swappiness=
#增加tcp支持的队列数
net.ipv4.tcp_max_syn_backlog =
#减少断开连接时 ，资源回收

net.core.netdev_max_backlog=
net.core.wmem_default=
net.core.wmem_max=
net.core.rmem_default=
net.core.rmem_max=
EOF sysctl -p
五、下载安装包
# 下载安装包：社区版 8.0.
cd /opt/
wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz
六、解压安装包
# 解压安装包
tar -xJf mysql-8.0.-linux-glibc2.-x86_64.tar.xz
cd /usr/local/
ln -s /opt/mysql-8.0.18-linux-glibc2.12-x86_64 mysql
七、创建用户
#、创建用户
groupadd mysql
useradd -g mysql mysql -d /home/mysql -s /sbin/nologin
八、创建对应的目录
#创建对应的目录
mkdir -p /data/mysql/mysql_3306/{data,logs,tmp,undolog}
九、创建配置文件
#、创建my.cnf配置文件
# 排除干扰因素
if [ -f /etc/my.cnf ]; then
mv /etc/my.cnf /etc/my.cnf.`date +%Y%m%d%H%M`.bak
