CentOS7.2.1511 安装Mysql-5.7.13

安装依赖包:
yum -y install gcc gcc-c++ ncurses ncurses-devel cmake
下载相应源码包：
wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.13.tar.gz
wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.13.tar.gz
wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz
添加mysql用户:
useradd -M -s /sbin/nologin mysql
预编译：
tar zxvf boost_1_59_0.tar.gz
cd boost_1_59_0 && ./bootstrap.sh && ./b2 && ./b2 install(解压就可以选择安装)
tar zxvf mysql-5.7.13.tar.gz
cd mysql-5.7.13
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DDOWNLOAD_BOOST=1 \  
-DWITH_BOOST=../boost_1_59_0 -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DENABLE_DTRACE=0 -DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_SYSTEMD=1
-DWITH_EMBEDDED_SERVER=1
(标红：加上-DWITH_SYSTEMD=1可以使用systemd控制mysql服务，默认是不开启systemd的)
编译安装：
make -j `grep processor /proc/cpuinfo | wc -l`
make install

cd /usr/local/mysql && chown -R mysql:mysql .    
bin/mysqld --initialize-insecure --user=mysql  --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
bin/mysql_ssl_rsa_setup
chown -R root . && chown -R mysql data  
(标红："--initialize"会生成一个随机密码(~/.mysql_secret)，而"--initialize-insecure"不会生成密码，--datadir目标目录下不能有数据文件)

mv /etc/my.cnf my.cnf.bak    ---将默认生成my.cnf改名或删除否则启动服务会报错
cd /usr/local/mysql/support-files     ---进入MySQL安装目录支持文件目录
cp my-default.cnf /etc/my.cnf    ---复制模板为新的配置文件，根据需要修改文件中配置选项如不修改配置MySQL则按默认配置参数运行。
       
## mysql默认将mysqld.service文件安装到了mysql安装目录下的usr/lib/systemd/system/，将mysqld.service复制到/usr/lib/systemd/system/目录下
cd /usr/local/mysql/ && cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
## 在mysqld.service，把默认的pid文件指定到了/var/run/mysqld/目录，而并没有事先建立该目录，因此要手动建立该目录并把权限赋给mysql用户。
cd /var/run && sudo mkdir mysqld  && sudo chown -R mysql mysqld  && sudo chgrp -R mysql mysqld  
## 启动mysql:
sysstemctl start mysqld

/usr/loca/mysql/bin/mysql -uroot    
use mysql;    
UPDATE user SET authentication_string = PASSWORD(‘test2015‘) WHERE user = ‘root‘;    
GRANT ALL PRIVILEGES ON *.* TO root@‘%‘ IDENTIFIED BY ‘rootpasswd‘;    
FLUSH PRIVILEGES;
## 创建用户：
create user bom;
update user set authentication_string=password("123456") where user="bom";
grant all on bom.* to ‘bom‘@‘localhost‘;
create user backup;
update user set authentication_string=password("123456") where user="backup";
grant all on *.* to ‘backup‘@‘localhost‘;
