安装mysql5.6
1、解压
tar -zxvf mysql-5.6.23.tar.gz

2、打补丁，下载补丁mysql-openssl.patch到mysql压缩包同一路径
cd mysql-5.6.23
patch -p1 < ../mysql-openssl.patch

3、编译安装，安装前确保已安装ncurses，ncurses-devel，gcc，gcc-c++，“Development tools”组，lrzsz，cmake
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_READLINE=1 -DWITH_SSL=bundled -DWITH_ZLIB=system -DWITH_EMBEDDED_SERVER=1 -DENABLED_LOCAL_INFILE=1
make && make install

4、后续配置
4.1、创建mysql组和mysql用户
groupadd mysql
useradd -s /sbin/nologin -M -g mysql mysql

4.2、修改my.cnf文件
## Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
[client]
#password   = your_password
port        = 3306
socket      = /tmp/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
datadir=/usr/local/mysql/var
port        = 3306

net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
lower_case_table_names=1

# Don‘t listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# but will not function as a master if omitted

【localhost】#sed -i ‘s:#innodb:innodb:g‘ /etc/my.cnf
              sed -i ‘s:/usr/local/mysql/data:/usr/local/mysql/var:g‘ /etc/my.cnf

4.3、初始化数据库
/usr/local/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/usr/local/mysql/var --user=mysql

chown -R mysql /usr/local/mysql/var
chgrp -R mysql /usr/local/mysql/.

cp support-files/mysql.server /etc/init.d/mysql

chmod 755 /etc/init.d/mysql

cat > /etc/ld.so.conf.d/mysql.conf<<EOF
    /usr/local/mysql/lib
    /usr/local/lib
EOF


4.4快捷方式，软连接
ln -sf /usr/local/mysql/lib/mysql /usr/lib/mysql
ln -sf /usr/local/mysql/include/mysql /usr/include/mysql

5、安全设置
5.1、启动mysql
 /etc/init.d/mysql start

 ln -sf /usr/local/mysql/bin/mysql /usr/bin/mysql
 ln -sf /usr/local/mysql/bin/mysqldump /usr/bin/mysqldump
 ln -sf /usr/local/mysql/bin/myisamchk /usr/bin/myisamchk
 ln -sf /usr/local/mysql/bin/mysqld_safe /usr/bin/mysqld_safe

5.2、设置mysql root密码
 /usr/local/mysql/bin/mysqladmin -u root password 123456

5.3、创建检查mysql安全脚本
touch mysql_sec_script.txt
vim mysql_sec_script.txt
输入以下文本
use mysql;
update user set password=password(‘123456‘) where user=‘root‘;
delete from user where not (user=‘root‘) ;
delete from user where user=‘root‘ and password=‘‘;
drop database test;
DROP USER ‘‘@‘%‘;
flush privileges;

/usr/local/mysql/bin/mysql -u root -p123456 -h localhost < mysql_sec_script.txt

rm -f mysql_sec_script.txt

echo -e "\nexpire_logs_days = 10" >> /etc/my.cnf
sed -i ‘/skip-external-locking/a\max_connections = 1000‘ /etc/my.cnf

6、Mysql附加
6.1、启动、重启、停止
启动mysql
/etc/init.d/mysql start
重启mysql
/etc/init.d/mysql restart
停止mysql
/etc/init.d/mysql stop

6.2、开机启动
vim /etc/rc.local
在最后添加以下行
/etc/init.d/mysql start

7.mysql远程连接
mysql -uroot -p123456
>use mysql;
>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘root‘ WITH GRANT OPTION;
>flush privileges;
>update user set password=PASSWORD("123456") where user=‘root‘;                        #1045错误
>quit
service mysql restart


8.LINUX下的MYSQL默认是要区分表名大小写的。
　　让MYSQL不区分表名大小写的方法其实很简单：
　　1.用ROOT登录，修改/etc/my.cnf
　　2.在[mysqld]下加入一行：lower_case_table_names=1
　　3.重新启动数据库即可
