Centos 6.10下安装MySQL5.6.48

一： 安装依赖

安装依赖包

yum install libaio numactl libncurses*  -y

二：创建用户

groupadd -f mysql
useradd -r -g mysql mysql

三：创建数据目录

mkdir -p /data/mysql_data 
chown mysql:mysql /data/mysql_data -R

四： 这里我们引入阿里云的MySQL5.6 高可用的配置模板

该配置模板好像不包括 主从复制的配置参数

五： 进行MySQL初始化

#下载安装包 mysql-5.6.48-linux-glibc2.12-x86_64.tar.gz

cd /usr/local/
tar zxf mysql-5.6.48-linux-glibc2.12-x86_64.tar.gz
ln -s mysql-5.6.48-linux-glibc2.12-x86_64 mysql
/usr/local/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql_data

六：修改启动脚本

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
vim /etc/init.d/mysqld
#修改配置
basedir=/usr/local/mysql
datadir=/data/mysql_data

七： 启动MySQL

/etc/init.d/mysqld start

八：进行安全配置

/usr/local/mysql/bin/mysql_secure_installation

 如果在进行MySQL安全设置时报错误如下：

Enter current password for root (enter for none):
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

此时则应该时mysql.sock的文件没有被正确找到，而且mysql_secure_installation 的并没有 -S 指定socket文件的选项。

修改mysql_secure_installation文件，大约150行，在sub make_config定义中加入 "socket=/data/mysql/mysql.sock"，修改完成如下

sub make_config {
  my $password = shift;

  my $esc_pass = basic_single_escape($rootpass);
  write_file($config,
             "# mysql_secure_installation config file",
             "[mysql]",
             "user=root",
             "password='$esc_pass'",
             "connect-expired-password",
             "socket=/data/mysql/mysql.sock");  #根据自己的设置；添加这一行
}

 

九：最后是自动化安装脚本

#!/bin/bash


#Cetnos6 下自动化安装MySQL脚本

echo "####安装依赖####"
yum install libaio numactl libncurses*  -y
sleep 1

echo "####创建MySQL用户####"
groupadd -f mysql
useradd -r -g mysql mysql

sleep 2

echo "####-创建数据目录-####"
mkdir -p /data/mysql_data
chown mysql:mysql /data/mysql_data -R
sleep 1

echo "####-手动上传mysql5.6.48到/usr/local/目录-####"
tar zxf mysql-5.6.48-linux-glibc2.12-x86_64.tar.gz
ln -s mysql-5.6.48-linux-glibc2.12-x86_64 mysql

#导入mysql配置文件
echo "引入阿里云MySQL配置文件模板"
