1、下载源码包
#wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.17.tar.gz
2、进入解压目录
cd mysql-5.7.17
3、安装相关依赖
[root@safehourse69 mysql-5.7.17]# yum install -y cmake gcc-c++* make ncurses-devel
2、4、创建mysql运行用户
[root@safehourse69 mysql-5.7.18]# useradd -M -s /sbin/nologin mysql
5、执行源码编译
#cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_DATADIR=/usr/local/mysql/data -DMYSQL-USER=mysql -DDOWNLOAD_BOOST=1 -DWITH_BOOST=./boost
3、编译之后，下面就是安装了，执行如下命令
#make -j 4 && make install
在编译的时候，如果虚拟机或是机器配置过低会报如下错误，建议配置为4核4G的配置来安装，我的安装是卡到75%这里，然后就不动了
cc1plus: warning: unrecognized command line option "-Wno-unused-local-typedefs"
调整完配置之后，再执行上面的安装命令
#make -j 4 && make install
7、更改文件夹属主和属组
chown -R mysql.mysql /usr/local/mysql/
8、手动添加编辑配置文件
[root@safehourse69 mysql-5.7.18]# cd /usr/local/mysql/support-files/
[root@safehourse69 support-files]# vim my-default.cnf
[mysqld]
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
socket = /tmp/mysql.sock
character-set-server=utf8
back_log = 300
max_connections = 3000
max_connect_errors = 50
table_open_cache = 4096
max_allowed_packet = 32M
#binlog_cache_size = 4M
max_heap_table_size = 128M
read_rnd_buffer_size = 16M
sort_buffer_size = 16M
join_buffer_size = 16M
thread_cache_size = 16
query_cache_size = 128M
query_cache_limit = 4M
ft_min_word_len = 8
thread_stack = 512K
transaction_isolation = REPEATABLE-READ
tmp_table_size = 128M
#log-bin=mysql-bin
long_query_time = 6
server_id=1
innodb_buffer_pool_size = 1G
innodb_thread_concurrency = 16
innodb_log_buffer_size = 16M
innodb_log_file_size = 512M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 90
innodb_lock_wait_timeout = 120
innodb_file_per_table = on
[mysqldump]
quick
max_allowed_packet = 32M
[mysql]
no-auto-rehash
default-character-set=utf8
safe-updates
[myisamchk]
key_buffer = 16M
sort_buffer_size = 16M
read_buffer = 8M
write_buffer = 8M
[mysqlhotcopy]
interactive-timeout
[mysqld_safe]
open-files-limit = 8192
[client]
9、初始化mysql服务
bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/
10、复制配置文件
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
11、复制启动脚本
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
12、修改启动脚本，在下面这个位置后面写上安装路径
vim /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
13、启动mysql 服务
cd /usr/local/mysql/bin/
./mysqld_safe --user=mysql &
service mysqld restart
Shutting down MySQL. SUCCESS!
Starting MySQL. SUCCESS!
14 做软连接，让系统直接调用
ln -s /usr/local/mysql/bin/* /bin/
15、登录数据库报如下错误，卡到这里了
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
系统没有找到mysql.sock文件
这里查看配置文件里写的是mysqld.sock 把配置文件里的mysqld.sock改成mysql.sock重启mysql 服务，就可以登录了
默认没有密码直接登录的
