1、官网下载地址：

https://cdn.MySQL.com//Downloads/MySQL-5.7/mysql-boost-5.7.29.tar.gz

【此包中含boost】

2、创建安装目录

mkdir -p /usr/local/mysql

mkdir -p /data/mysql/data

3、创建用户和组

groupadd mysql

useradd -g mysql mysql

4、授权

chown -R mysql.mysql /usr/local/mysql

chown -R mysql.mysql /data/mysql/data

5、安装依赖包

yum -y install make gcc gcc-c++ cmake bison-devel ncurses ncurses-devel openssl-devel bison

6、cmake编译

cmake

-DWITH_BOOST=boost/boost_1_59_0

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql

-DMYSQL_DATADIR=/data/mysql/data

-DSYSCONFDIR=/etc

-DWITH_MEMORY_STORAGE_ENGINE=1

-DWITH_MYISAM_STORAGE_ENGINE=1

-DWITH_INNOBASE_STORAGE_ENGINE=1

-DWITH_READLINE=1

-DMYSQL_UNIX_ADDR=/tmp/mysql.sock

-DMYSQL_TCP_PORT=3306

-DENABLED_LOCAL_INFILE=1

-DWITH_PARTITION_STORAGE_ENGINE=1

-DEXTRA_CHARSETS=all

-DDEFAULT_CHARSET=utf8mb4

-DDEFAULT_COLLATION=utf8mb4_general_ci

-DWITH_SSL=system

7、make编译

make

【lscpu

make -j [需要添加编译的cpu数量，提高编译速度] 】

8、vi /etc/my.cnf

[mysqld]

basedir=/usr/local/mysql

datadir=/data/mysql/data

socket=/tmp/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

skip-name-resolve

#innodb_buffer_pool_size=2048M

max_connections=500

collation_server=utf8_bin

character_set_server=utf8

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

lower_case_table_names=0

key_buffer_size = 600M

max_allowed_packet = 100M

table_open_cache = 1024

sort_buffer_size = 6M

read_buffer_size = 6M

read_rnd_buffer_size = 8M

myisam_sort_buffer_size = 64M

thread_cache_size = 64

query_cache_size = 256M

innodb_log_file_size = 1024M

innodb_log_files_in_group = 3

#log-error=/usr/local/mysql/log/mysqld.log

[client]

default-character-set = utf8

9、初始化

cd /usr/local/mysql

./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data/

10、环境变量设置

echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile

source /etc/profile

11、复制启动文件:

cp support-files/mysql.server /etc/init.d/mysqld

chmod 755 /etc/init.d/mysqld

12、启动数据库：

/etc/init.d/mysqld start

13、修改临时密码

alter user 'root'@'localhost' identified by 'ik0@110';

14、添加到开发服务

chkconfig --add /etc/init.d/mysqld

15、设置开机启动

chkconfig mysqld on

99、MySQL忘记root密码

解决方法：

1）在my.cnf中加上skip-grant-tables后 service mysqld restart

2）登录后执行

update mysql.user set authentication_string=password(‘jew@110’) where user=‘root’;

flush privileges;

3）执行成功后将my.cnf 文件改回去，重启MySQL，使用新密码登录，MySQL已安装完成。

4）然后mysql就可以连接了，但此时操作似乎功能不完全，还要alter user…

mysql> alter user 'root'@'localhost' identified by 'qldassword(‘r31@110’) where user=‘root’;

flush privileges;

3）执行成功后将my.cnf 文件改回去，重启MySQL，使用新密码登录，MySQL已安装完成。

4）然后mysql就可以连接了，但此时操作似乎功能不完全，还要alter user…

mysql> alter user 'root'@'localhost' identified by 'qld@110';
