1.准备环境
准备一台有两个硬盘的服务器，第二个硬盘20g容量，用于放置mysql的程序，以及数据.
2.安装解决依赖包 yum install -y ncurses-devel libaio-devel
3.安装cmake yum install cmake -y
4.创建用户 useradd -s /sbin/nologin -M mysql -u 999
5.格式化磁盘、挂载磁盘 mkfs.ext4 /dev/sdb mkdir /application mount /dev/sdb /application
6.开机自动挂载磁盘 blkid查看sdb盘的uuid 修改/etc/fstab开机自动挂载------UUID=a57ef7da-19eb-4a5e-8487-21e3d9ccb6fb /application ext4 defaults 0 0
7.上传并解压mysql的安装包 tar xf mysql-5.6.39.tar.gz
8.编译安装包 cd /application/tools/mysql-5.6.39
cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.6.39
-DMYSQL_DATADIR=/application/mysql-5.6.39/data
-DMYSQL_UNIX_ADDR=/application/mysql-5.6.39/tmp/mysql.sock
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci
-DWITH_EXTRA_CHARSETS=all
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_FEDERATED_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1
-DWITH_ZLIB=bundled
-DWITH_SSL=bundled
-DENABLED_LOCAL_INFILE=1
-DWITH_EMBEDDED_SERVER=1
-DENABLED_DOWNLOADS=1
-DWITH_DEBUG=0
9.make && make install
10.创建软链接 ln -s /application/mysql-5.6.39/ /application/mysql
11.修改安装目录权限 chown -R mysql.mysql /application/mysql/
12.初始化及配置数据库 cp support-files/my*.cnf /etc/my.cnf
/application/mysql/scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data --user=mysql
13.配置启动文件 cp support-files/mysql.server /etc/init.d/mysqld chmod 700 /etc/init.d/mysqld
14.mysql开机自启动 chkconfig mysqld on /etc/init.d/mysqld start
15.启动时可能报错解决 mkdir /application/mysql/tmp chown -R mysql.mysql /application/mysql/ 原因：5.6.39版本不会自动创建tmp目录 netstat -lntup|grep 3306
** 16.修改环境变量** echo "PATH='/application/mysql/bin/:$PATH'" >>/etc/bashrc source /etc/bashrc
17.设置密码 mysqladmin -u root -p password "123456" mysql -uroot -p123456
18.优化数据库删除不安全的库 select user,host,password from mysql.user; drop user 'root'@'db02'; drop user 'root'@'::1'; drop user ''@'localhost'; drop user ''@'db02'; drop database test;
