CentOS6.9编译安装MySQL5.7.16
部署环境：
系统CentOS6.9，mysql5.7.16，boost库
系统为2G内存
1、安装依赖包,使用yum安装cmake，6.9默认yum源自带
yum -y install gcc-c++ cmake bison-devel ncurses-devel
2、创建mysql的用户：
useradd -U -s /sbin/nologin mysql
3、创建必要的文件夹，并修改其目录用户所有者：
mkdir -pv /usr/local/mysql/etc
mkdir -pv /data/{boost/boost_1_59_0,mysql/{data,log}}
chown -R mysql:mysql /usr/local/mysql/
chown -R mysql:mysql /data/mysql/
4、将boots库拷贝到boost目录下
cp /tmp/boost/boost_1_59_0/* /data/boost/boost_1_59_0
chown -R mysql:mysql /data/boost/
5、编译安装mysql5.7
cd /tmp
tar xf mysql-5.7.16.tar.gz
cd mysql-5.7.16
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql/data \
-DSYSCONFDIR=/usr/local/mysql/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=/data/mysql/log/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_BOOST=/data/boost/boost_1_59_0
make && make install
时间比较长
chown -R mysql:mysql /usr/local/mysql
6、配置文件my.cnf

[mysql]
default-character-set = utf8
[mysqld]
# file

7、初始化数据库
版本在5.7.6前用的是mysql_install_db
版本5.7.6之后使用的mysqld --initialize
#####################官网标注#####################################
shell> bin/mysql_install_db --user=mysql # MySQL 5.7.5
shell> bin/mysqld --initialize --user=mysql # MySQL 5.7.6 and up
shell> bin/mysql_ssl_rsa_setup # MySQL 5.7.6 and up
#####################官网标注#####################################
/usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/data/mysql/data --basedir=/usr/local/mysql
可能会出现内存不够的报错，自己优化下调节一下buffer大小就行了
/usr/local/mysql/bin/mysql_ssl_rsa_setup
没有打印日志，临时密码不能用，只好破解了，后面有方法。
8、启动数据库
vim /usr/local/mysql/support-files/mysql.server
加上绝对路径
basedir=/usr/local/mysql
datadir=/data/mysql/data
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
service mysqld start
9、配置环境变量
vim /etc/profile
export PATH=/usr/local/mysql/bin:$PATH
source /etc/profile
10、查看mysql临时密码，这项我这不用了，不好使，直接破解了。
cat /root/.mysql_secret
mysql -uroot -p`cat /root/.mysql_secret`
如果能进去，基本上到这就截止了，可以正常使用了。
**不能正常登录，使用临时密码无法登进去**
11、破解密码
mysqld_safe --defaults-file=/usr/local/mysql/etc/my.cnf --skip-grant-tables --skip-networking&
update mysql.user set authentication_string=password('123456') where user='root';
11.1、查找进程号，杀掉mysql进程
ps aux | grep mysql
kill -9 pid
service mysqld start
11.2、登录mysql
mysql -u root -p 'password'
提示修改密码：
mysql> alter user root@localhost identified by '123456';
ok了
