Mysql5.7版本有较大的变化，特别是在mysql主从上面，可以提供并行复制，所以效率上更高，以后如果有类似需求，需要提供主从复制的话，建议事业部同事选择5.7的版本。
选择安装的包都为源码包，定义起来较为方便，由于全部都为文字节目操作，所以截图部分较少。
一. mysql 安装
1. 基础包安装
a. 首先清理自带的mysql相关的包
i. yum -y remove mysql-*
b. 安装编译mysql需要包
i. yum install gcc gcc-c++ -y
ii. yum install ncurses-devel –y
iii. cmake 安装，版本要求2.8或者3.0以上的
tar xvf cmake*
cd cmake-3.4.3
./configure
make –j 10 ---------------数字为表cpu核数，并行执行，加快编译速度
make install
注意：boost也为mysql编译必须的包，5.7对其版本也有要求，下载mysql包含boost的就无需手动在安装了---------下面步骤可略过
tar xvf boost*
cd boost_1_61_0
./bootstrap.sh –prefix=/usr/local/
./b2
./b2 install
2. mysql环境准备
a. mkdir -pv /data/mysql
b. useradd -s /sbin/nologin mysql
c. chown -R mysql.mysql /data/mysql
3. 编译安装mysql
a. tar xvf mysql-boost-5.7.12.tar.gz
b. cd mysql-5.7.12
c. cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=/opt/package/boost_1_59_0/ ----------制定mysql安装目录、默认字符集、boost路径
d. make -j 40 && make install
4. mysql初始化
a. 建立mysql配置文件 /etc/my.cnf -----无论需不需要配置主从，都建议先把server-id以及log-bin配置了，避免以后有添加配置主从的要求
拷贝配置文件模板为新的mysql配置文件
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
# cat /etc/my.cnf
[client]
port = 3306
socket = /tmp/mysql.sock
default-character-set = utf8mb4
[mysqld]
port = 3306
socket = /tmp/mysql.sock
basedir = /usr/local/mysql
datadir = /data/mysql
pid-file = /data/mysql/mysql.pid
user = mysql
server-id = 29
init-connect = 'SET NAMES utf8mb4'
character-set-server = utf8mb4

b. /usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql -------注意5.7之前的版本用mysql_install_db初始化
例如：./scripts/mysql_install_db --datadir=/data/mysql5.6/ --user=mysql --basedir=/usr/local/mysql5.6/ --defaults-file=/etc/my.cnf.5.6
启动: /usr/local/mysql5.6/bin/mysqld_safe --defaults-file=/etc/my56.cnf &
关闭：mysqladmin –u root -h 127.0.0.1 –port 3307 shutdown
mysqladmin -uroot -p1234#Byd -S /tmp/mysql5.6.sock shutdown
安装多个实例，旧版本初始化时候要指定—defaults-file
然后初始化密码时候也要指定对应的端口或者socket，例如:
/usr/local/mysql5.6/bin/mysqladmin -u root -h 127.0.0.1 --port 3307 password 'password'
/usr/local/mysql5.6/bin/mysqladmin -u root --socket --port 3307 password 'password'
c. 启动mysql， /usr/local/mysql/bin/mysqld_safe &
d. 设置mysql root登陆密码：/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'127.0.0.1' identified by \"1234#Byd\" with grant option;"
/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'localhost' identified by \"1234#Byd\" with grant option;"
e. 其他，配置mysql服务以及mysql bin环境变量
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
chmod 755 !$
可以通过 service mysql start/status/stop 管理
ln -s /usr/local/mysql/bin/* /usr/local/bin/
登陆Mysql:mysql -u root -p1234#Byd
二. 主从配置
1. 安装上面的操作配置主从，先把mysql先配置了（下面主从仅适用于新安装的，已有的数据库，要求有配置server-id,以及开启二进制日志的前提下才可以配置主从，需要先把主库导出，然后配置同步）
2. 主从差异，配置文件server-id不同即可
3. 在主库上创建用于复制的用户
grant replication slave on *.* to slave@'10.9.31.%' identified by 'slave#2016?';
4. 主库查询状态：查询当前日志文件及position，用于日志恢复
5、从库配置到主库的复制
change master to master_host='10.9.31.27',master_user='slave',master_password='slave#2016?',master_log_file='mysql-bin.000004',master_log_pos=1225;
开启复制：start slave;
查看复制状态：show slave status\G; 查询到复制的IO和SQL线程都为YES表示配置成功。
6. 验证
在主库创建库或者表，在从库查询。
注意：5.6以上版本开启了GTID特性，mysql自己识别复制log及pos，方便管理；由于上面my.cnf已经开启了gtid，可以使用该特性完成复制
1：配置账号
grant replication slave,replication client on *.* to repl@'10.9.31.29' identified by 'Repl#2016';
change master to master_host='10.9.31.26',master_port=3306,master_user='repl',master_password='Repl#2016',master_auto_position=1;
启动复制
start slave;
show slave status\G;
show processeslist;
