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 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
# 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

# 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
