1.下載安裝包

MySQL 官方下載地址：https://dev.mysql.com/downloads/mysql/? MySQL 5.7官方安裝文檔：https://dev.mysql.com/doc/refman/5.7/en/binary-installation.html

2.安裝依賴包

MySQL依賴于libaio 庫。如果這個庫沒有在本地安裝，數據目錄初始化和后續的服務器啟動步驟將會失敗。請使用適當的軟件包管理器進行安裝。例如，在基于Yum的系統上： shell> yum search libaio? shell> yum install libaio

3.創建一個mysql用戶和組

shell> groupadd mysql shell> useradd -r -g mysql -s /bin/false mysql

4.解壓到指定目錄

shell> tar -zxvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz -C /usr/local shell> cd /usr/local shell> mv mysql-5.7.21-linux-glibc2.12-x86_64 mysql

5.配置數據庫目錄

數據目錄：/usr/local/mysql/data? 參數文件my.cnf：/usr/local/mysql/etc/my.cnf? 錯誤日志log-error：/usr/local/mysql/log/mysql_error.log? 二進制日志log-bin：/usr/local/mysql/log/mysql_bin.log? 慢查詢日志slow_query_log_file：//usr/local/mysql/log/mysql_slow_query.log? 套接字socket文件：/usr/local/mysql/run/mysql.sock? pid文件：/usr/local/mysql/run/mysql.pid? shell> mkdir -p /usr/local/mysql/{data,log,etc,run} shell> chown -R mysql:mysql /usr/local/mysql? shell> chmod 750 /usr/local/mysql/{data,log,etc,run}

6.配置my.cnf文件

在/usr/local/mysql/etc/下創建my.cnf文件，加入如下參數，其他參數根據需要配置 [client] port = 3306 socket = /usr/local/mysql/run/mysql.sock [mysqld] port = 3306 socket = /usr/local/mysql/run/mysql.sock pid_file = /usr/local/mysql/run/mysql.pid datadir = /usr/local/mysql/data default_storage_engine = InnoDB max_allowed_packet = 128M max_connections = 2048 open_files_limit = 65535 skip-name-resolve lower_case_table_names=1 character-set-server = utf8mb4 collation-server = utf8mb4_unicode_ci init_connect='SET NAMES utf8mb4' innodb_buffer_pool_size = 128M innodb_log_file_size = 128M innodb_file_per_table = 1 innodb_flush_log_at_trx_commit = 0 key_buffer_size = 16M log-error = /usr/local/mysql/log/mysql_error.log log-bin = /usr/local/mysql/log/mysql_bin.log slow_query_log = 1 slow_query_log_file = /usr/local/mysql/log/mysql_slow_query.log long_query_time = 5 tmp_table_size = 16M max_heap_table_size = 16M query_cache_type = 0 query_cache_size = 0 server-id=1

7.設置臨時密碼

grep 'temporary password' /usr/local/mysql/log/mysql_error.log

8.初始化

/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql--datadir=/usr/local/mysql/data --initialize 9.將mysqld設置開啟自動啟動 cp /usr/local/mysql/support-files/mysql.server? ? /etc/init.d/mysqld chkconfig --add mysqld 10.復制配置文件my.cnf cp /usr/local/mysql/etc/my.cnf??? /etc/my.cnf? (提示覆蓋就覆蓋) 11.啟動mysql服務 service mysql start 12.進入mysql cd?/usr/local/mysql/bin? ./ mysql -u root -p(臨時密碼) 13.修改密碼 重新設置密碼 SET PASSWORD FOR'root'@localhost=PASSWORD('admin'); ? #對應的換成你自己的密碼即可 14、開啟遠程權限 grant all privileges on *.* to '新用戶名'@'%' identified by '新密碼'; flush privileges; 15.配置環境變量 vim /etc/profile export PATH=/usr/local/mysql/bin:$PATH source /etc/profile
