cd /usr/src/mysql-5.7.12
编译
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/3306/data \
-DMYSQL_TCP_PORT=3306 \

在这里特别提醒,对于mysql5.7的make编译,如果是云主机,会在make编译到45%时会报错,这是内存不足所致
c++: Internal error: Killed (program cc1plus)
Please submit a full bug report.
See <http://bugzilla.redhat.com/bugzilla> for instructions.
make[2]: *** [sql/CMakeFiles/sql.dir/item_geofunc.cc.o] Error 1
make[1]: *** [sql/CMakeFiles/sql.dir/all] Error 2
make: *** [all] Error 2
创建2G的交换分区
dd if=/dev/zero of=/swapfile bs=1k count=2048000 --获取要增加的2G的SWAP文件块
mkswap /swapfile -- 创建SWAP文件
swapon /swapfile -- 激活SWAP文件
swapon -s -- 查看SWAP信息是否正确
出错后重新运行配置，需要删除CMakeCache.txt文件
make clean
rm -f CMakeCache.txt
重新运行
cmake -DCMAKE_INSTALL_PREFIX**************** 参数
编译完后, 如果不想要交换分区了, 可以删除:
swapoff /swapfile
rm -fr /swapfile

初始化
/usr/local/mysql/scripts/mysql_install_db \
--basedir=/usr/local/mysql \
--datadir=/data/3306/data \
--user=mysql
编辑配置文件
cd /usr/local/mysql
cp my.cnf my.cnf.bak
vi my.cnf
删除注视行，添加如下内容:
basedir = /usr/local/mysql
datadir = /data/3306/data
port = 3306
server_id = 2
socket = /data/3306/mysqld.sock
pid-file = /data/3306/mysql.pid
max_allowed_packet=16M
log-error = /data/3306/logs/error.log
设置文件权限
chown mysql:mysql -R /data/3306 /usr/local/mysql
复制启动脚本
cp /usr/src/mysql-5.6.23/support-files/mysql.server /etc/init.d/mysqld
添加脚本权限，加入开机自启动
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig --level 2345 mysqld on
编辑环境变量
vi /etc/profile
最后一行添加
PATH=$PATH:/usr/local/mysql/bin
重新加载环境变量
source /etc/profile
启动数据库
/etc/init.d/mysqld start
初始化
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/3306/data
以root初始化操作时要加–user=mysql参数，生成一个随机密码（注意保存登录时用）

备份配置文件
cd /etc/
mv my.cnf my.cnf.bak
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
编辑配置文件
vi my.cnf
basedir = /usr/local/mysql
datadir = /data/3306/data
port = 3306
server_id = 2
socket = /data/3306/mysqld.sock
pid-file = /data/3306/mysql.pid
max_allowed_packet=16M
log-error = /data/3306/logs/error.log
chown mysql:mysql -R /data/3306 /usr/local/mysql
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig --level 2345 mysqld on
编辑环境变量
vi /etc/profile
最后一行添加
PATH=$PATH:/usr/local/mysql/bin
重新加载环境变量，启动mysql
source /etc/profile
/etc/init.d/mysqld start
进入Mysql
mysql -u root -p
输入密码: &iiaod5Z/f:H
必须修改密码,否则提示
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
修改密码为root
alter user ‘root‘@‘localhost‘ identified by ‘root‘;
quit;
再次进入
mysql -u root -proot
执行命令，就可以了
