上传文件并解压
[root@MySQL ~]# cd /usr/local/ [root@MySQL local]# ls mysql* mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz [root@MySQL local]# tar zxvf mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz
解压完毕之后创建软连接
[root@MySQL local]# ln -s mysql-5.7.9-linux-glibc2.5-x86_64 mysql [root@MySQL local]# cd mysql [root@MySQL mysql]# ll total 160 drwxr-xr-x 2 7161 wheel 4096 Oct 12 2015 bin -rw-r--r-- 1 7161 wheel 17987 Oct 12 2015 COPYING drwxr-xr-x 2 7161 wheel 4096 Oct 12 2015 docs drwxr-xr-x 3 7161 wheel 4096 Oct 12 2015 include -rw-r--r-- 1 7161 wheel 108028 Oct 12 2015 INSTALL-BINARY drwxr-xr-x 5 7161 wheel 4096 Oct 12 2015 lib drwxr-xr-x 4 7161 wheel 4096 Oct 12 2015 man -rw-r--r-- 1 7161 wheel 2478 Oct 12 2015 README drwxr-xr-x 28 7161 wheel 4096 Oct 12 2015 share drwxr-xr-x 2 7161 wheel 4096 Oct 12 2015 support-files
创建用户及组
[root@MySQL mysql]# groupadd mysql
[root@MySQL mysql]# useradd -r -g mysql mysql
为mysql路径下面的文件进行用户和组的修改
[root@MySQL mysql]# chown -R mysql . [root@MySQL mysql]# chgrp -R mysql .
创建数据文件和日志文件路径
[root@MySQL local]# mkdir /mydata /mydata/data /mydata/log [root@MySQL mysql]# chown -R mysql:mysql /mydata
创建my.cnf文件
[root@MySQL mysql]# vi /etc/my.cnf [client] port = 3306 socket = /var/lib/mysql/mysql.sock [mysqld] server_id=10 port = 3306 user = mysql character-set-server = utf8mb4 default_storage_engine = innodb log_timestamps = SYSTEM socket = /var/lib/mysql/mysql.sock basedir = /usr/local/mysql datadir = /mydata/data pid-file = /mydata/data/mysql.pid max_connections = 1000 max_connect_errors = 1000 table_open_cache = 1024 max_allowed_packet = 128M open_files_limit = 65535 #####====================================[innodb]============================== innodb_buffer_pool_size = 1024M innodb_file_per_table = 1 innodb_write_io_threads = 4 innodb_read_io_threads = 4 innodb_purge_threads = 2 innodb_flush_log_at_trx_commit = 1 innodb_log_file_size = 512M innodb_log_files_in_group = 2 innodb_log_buffer_size = 16M innodb_max_dirty_pages_pct = 80 innodb_lock_wait_timeout = 30 innodb_data_file_path=ibdata1:1024M:autoextend #####====================================[log]============================== log_error = /mydata/log/mysql-error.log slow_query_log = 1 long_query_time = 1 slow_query_log_file = /mydata/log/mysql-slow.log sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
初始化数据库
在5.7.6之前初始化的方法是：bin/mysql_install_db --user=mysql
5.7.6之后的版本初始化数据库不再使用mysql_install_db
[root@MySQL mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/mydata/data --innodb_undo_tablespaces=3 --explicit_defaults_for_timestamp
[root@MySQL mysql]# bin/mysql_ssl_rsa_setup --datadir=/mydata/data
如果配置了my.cnf的log_error，那么初始密码在log_error文件中，否则会打印出来。
初始完毕之后更改/usr/local/mysql路径下面文件的所属用户
[root@MySQL mysql]# chown -R root .
配置启动文件
cp support-files/mysql.server /etc/init.d/mysql chkconfig --add mysql chkconfig mysql on service mysql start
配置环境变量
[root@MySQL ~]# vi /etc/profile mysql_home=/usr/local/mysql PATH=$PATH:$mysql_home/bin source /etc/profile
修改密码
在5.7中存储密码的字段不再是password了，变成了authentication_string
update mysql.user set authentication_string=password(‘root‘) where user=‘root‘;
修改root密码后如果第一次使用root用户登入mysql系统还会需要重置一次root密码
SET PASSWORD=PASSWORD(‘root‘);
flush privileges;
