系统是cenos6.7 64位的，默认mysql5.7.11下载到/usr/local/src,安装目录在/app/local/mysql目录下，mysql数据放置目录/app/local/data。mysql从5.1后采用cmake方式编译安装，所以要先编译安装cmake工具，也可以采用yum方式安装cmake。从mysql5.7开始编译安装需要boost库的支持，所以也要下载boost库
#wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.11.tar.gz
#wget https://cmake.org/files/v3.1/cmake-3.1.3.tar.gz
#wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
如果没有mysql用户则新建mysql用户。
#groupadd mysql
#useradd -g mysql mysql -s /bin/false
创建相应的目录
#mkdir -p /app/local/{mysql,data}
#mkdir /usr/local/boost
编译安装cmake
#tar zxvf cmake-3.1.3.tar.gz
#cd cmake-3.1.3
#./configure
#make && make install
#cd ../
将boost库解压到/usr/local/boost目录下
#tar zxvf boost_1_59_0.tar.gz
#cd boost_1_59_0/
#mv ./* /usr/local/boost/
#cd ../
编译安装mysql5.7.11
#tar zxvf mysql-5.7.11.tar.gz
#cd mysql-5.7.11
#cmake -DCMAKE_INSTALL_PREFIX=/app/local/mysql/ -DMYSQL_DATADIR=/app/local/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost
#make && make install
#cd ../
#chown -R mysql:mysql /app/local/data/
#chown -R mysql:mysql /app/local/mysql/
#cd /app/local/mysql/bin
#./mysqld --initialize --user=mysql --basedir=/app/local/mysql/ --datadir=/app/local/data/#初始化mysql 并且生成一个随机密码
#mv /etc/my.cnf /etc/my.cnfbak#先备份生成的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
#chkconfig mysqld on
#service mysqld start
#mysql -uroot -p
Enter password:
用刚才生成的随机密码登录
要是不行，就在my.cnf里配置password
登录后重置root密码
mysql> SET PASSWORD FOR ‘root‘@localhost = PASSWORD（‘123456‘）；
Query OK, 0 rows affected, 1 warning (0.00 sec)
就可以了
