mysql8.0.15二进制安装

mysql8.0.15二进制安装

　　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老师，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/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

# 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 = 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

# 第二部分：mysql的安装配置

# 1、下载安装包
# 社区版 8.0.15

cd /opt/
wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.15-linux-glibc2.12-x86_64.tar.xz

# 2、解压安装包

tar -xJf mysql-8.0.15-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-8.0.15-linux-glibc2.12-x86_64 mysql

# 4、创建用户

groupadd mysql
useradd -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}

# 6、创建配置文件

# 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
