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
#1、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
#2、关闭selinux sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config setenforce 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 65535 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=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 = 8000 net.ipv4.tcp_tw_reuse = 1 #net.ipv4.tcp_tw_recycle = 1 net.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=65535 net.core.wmem_default=87380 net.core.wmem_max=16777216 net.core.rmem_default=87380 net.core.rmem_max=16777216 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=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 = 8000 net.ipv4.tcp_tw_reuse = 1 #net.ipv4.tcp_tw_recycle = 1 net.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=65535 net.core.wmem_default=87380 net.core.wmem_max=16777216 net.core.rmem_default=87380 net.core.rmem_max=16777216 EOF sysctl -p
五、下载安装包
# 下载安装包：社区版 8.0.18 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-8.0.18-linux-glibc2.12-x86_64.tar.xzcd /usr/local/ln -s /opt/mysql-8.0.18-linux-glibc2.12-x86_64 mysql
七、创建用户
#7、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
#9、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
fi
