一、源码安装cmake工具
从mysql5.5起，mysql源码安装开始使用cmake
wget http://cmake.org/files/v3.2/cmake-3.2.3.tar.gz
tar zxvf cmake-3.2.3.tar.gz
cd cmake-3.2.3
./bootstrap
make
make install
cd ..
二、安装MySQL所需依赖包
yum -y install ncurses-devel libtool openssl-devel
三、安装MySQL
wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.26.tar.gz
useradd -r -s /sbin/nologin mysql
mkdir -pv /usr/local/mysql/data
tar zxvf mysql-5.6.26.tar.gz
cd mysql-5.6.26
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data/ -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DWITH_INNOBASE_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DMYSQL_TCP_PORT=3306 -DSYSCONFDIR=/etc -DENABLE_DOWNLOADS=1
#出现错误，下次需要：rm -rf CMakeCache.txt
make
make install
rm -rf /etc/my.cnf
cp support-files/my-default.cnf /etc/my.cnf
cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
chown -R mysql.mysql /usr/local/mysql/
##初始化数据库
chmod +x scripts/mysql_install_db
scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/
ln -s /usr/local/mysql/bin/* /usr/bin/
ln -s /usr/local/mysql/lib/* /usr/lib/
ln -s /usr/local/mysql/man/man1/* /usr/share/man/man1
ln -s /usr/local/mysql/man/man8/* /usr/share/man/man8
ln -s /usr/local/mysql/libexec/* /usr/local/libexec
四、启动mysql服务并加入开机自启动
service mysqld start
chkconfig mysqld on
五、验证mysql服务是否启动
netstat -tulnp | grep 3306 mysql
六、运行MySQL安全设置脚本
修改MySQL用户root的密码，同时可禁止root远程连接，移除test数据库和匿名用户。
mysql_secure_installation
所有选Y即可，也可根据个人爱好
七、MySQL相关
设置mysql登陆密码
例：
mysqladmin -u root password "111111"
