环境：
1 [root@node ~]# cat /etc/redhat-release 2 CentOS Linux release 7.2.1511 (Core) 3 [root@node ~]# uname -a 4 Linux node 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux 5 [root@node ~]#

创建用于MySQL使用的用户和用户组及数据存放目录：
1 [root@node tools]# groupadd mysql 2 [root@node tools]# useradd -g mysql mysql -s /sbin/nologin 3 [root@node tools]# mkdir -p /data/mysql 4 [root@node tools]# chown -R mysql.mysql mysql 5 [root@node tools]# chown -R mysql.mysql /data/mysql/
解压MySQL二进制包，移到指定位置(/usr/local目录)，并创建软链接
1 [root@node local]# ln -s mysql-5.6.40-linux-glibc2.12-x86_64 mysql 2 [root@node local]# chown -R mysql.mysql mysql 3 [root@node local]# chown -R mysql.mysql /data/mysql/ 4 [root@node local]#
调整配置文件my.cnf。

出现两个OK，说明初始化数据库成功。
接下来启动数据库：
1 [root@node scripts]# cd /usr/local/mysql/bin/ 2 [root@node bin]# ./mysqld_safe --defaults-file=/etc/my.cnf & 3 [1] 2950 4 [root@node bin]# 180507 02:13:27 mysqld_safe Logging to '/data/mysql/error.log'. 5 180507 02:13:27 mysqld_safe Starting mysqld daemon with databases from /data/mysql 6 7 [root@node bin]# 8 [root@node bin]# 9 [root@node bin]# ps xua|grep mysql 10 root 2950 0.7 0.0 113252 1616 pts/1 S 02:13 0:00 /bin/sh ./mysqld_safe --defaults-file=/etc/my.cnf 11 mysql 3583 4.5 30.3 1483272 567324 pts/1 Sl 02:13 0:00 /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/data/mysql --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/data/mysql/error.log --open-files-limit=65535 --pid-file=node.pid --socket=/tmp/mysql.sock --port=3306 12 root 3606 0.0 0.0 112644 952 pts/1 S+ 02:13 0:00 grep --color=auto mysql 13 [root@node bin]# netstat -lnupt|grep mysql 14 tcp6 0 0 :::3306 :::* LISTEN 3583/mysqld 15 [root@node bin]#
MySQL5.6默认情况下启动后可以用空密码登录，直接修改密码：
1 [root@node bin]# ./mysql 2 Welcome to the MySQL monitor.

至此，MySQL5.6数据库二进制安装完成。
如果正常关闭数据库用如下命令：
1 [root@node bin]# ./mysqladmin -uroot -hlocalhost -p shutdown 2 Enter password: 3 [root@node bin]# 4 [root@node bin]# ps xua|grep mysql 5 root 3620 0.0 0.0 112644 948 pts/1 S+ 02:18 0:00 grep --color=auto mysql 6 [root@node bin]# netstat -lnupt|grep 3306 7 [root@node bin]#
一般便于操作，可以将MySQL的执行文件所在路径添加到系统环境变量PATH中：
1 [root@node bin]# pwd 2 /usr/local/mysql/bin 3 [root@node bin]# echo 'export PATH=/usr/local/mysql/bin:$PATH' >>/etc/profile 4 [root@node bin]# source /etc/profile 5 [root@node bin]# cd 6 [root@node ~]# mysql 7 mysql mysql_config mysql_embedded mysqlslap 8 mysqlaccess mysql_config_editor mysql_find_rows mysqltest 9 mysqlaccess.conf mysql_convert_table_format mysql_fix_extensions mysqltest_embedded 10 mysqladmin mysqld mysqlhotcopy mysql_tzinfo_to_sql 11 mysqlbinlog mysqld-debug mysqlimport mysql_upgrade 12 mysqlbug mysqld_multi mysql_plugin mysql_waitpid 13 mysqlcheck mysqld_safe mysql_secure_installation mysql_zap 14 mysql_client_test mysqldump mysql_setpermission 15 mysql_client_test_embedded mysqldumpslow mysqlshow 16 [root@node ~]# mysql
这样我们可以在任何路径下直接执行MySQL相关的密令(即：/usr/local/mysql/bin目录下的可执行文件)
