wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.23.tar.gz 解壓
tar zxvf mysql-5.6.23.tar.gz 安裝編譯環境
sudo yum install cmake gcc-c++ ncurses-devel perl-Data-Dumper 編譯安裝
進入mysql源碼目錄，生成makefile
cmake .
make
make installmysql將會安裝到/usr/local/mysql路徑。
修改目錄和文件權限，初始化數據庫
cd /usr/local/mysql
sudo chown -R mysql .
sudo chgrp -R mysql .
sudo scripts/mysql_install_db --user=mysql 修改my.cnf文件
/etc下默認存在my.cnf文件干擾mysql運行，需要先刪掉，然後再/etc下重建my.cnf文件，內容如下：
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = /data/mysql/data
# port = .....
# server_id = .....
# socket = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
max_connection = 10000
sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
#binary log
log-bin = mysql-bin
binlog_format = mixed
expire_logs_day = 30
#slow query log
slow_query_log = 1
slow_query_log_file = /var/log/mysql/slow.log
long_query_time = 3
log-queries-not-using-indexes
log-slow-admin-statements 將mysql加入到系統服務中：
cp support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
service mysql start附：可能出現下面問題：
Starting MySQL................ ERROR! The server quit without updating PID file (/usr/local/mysql/data/localhost.localdomain.pid).說明需要給/usr/local/mysql/data目錄讀寫權限這裏直接用：
sudo chmod 777 /usr/local/mysql/data還需要重啓機器：
reboot還有將mysql命令加入環境變量：
export PATH=/usr/local/mysql/bin:$PATH安裝5.6版本的初始化工具
執行命令行(前提是mysql已經啓動)：
mysql_secure_installation按照提示初始化即可
以上
