mysql5.7
環境:虛擬機+centos7
1.下載二進制包，下面mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz鏈接是官網
cd /usr/local/src
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz
2.解壓，改名
[[email protected] src]# tar zxvf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz
[[email protected] src]# ls index.html?id=471614 mysql-5.7.19-linux-glibc2.12-x86_64 mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz [[email protected] src]# mv mysql-5.7.19-linux-glibc2.12-x86_64 /usr/local/mysql
3. 初始化
[[email protected] mysql]# useradd -M -s /sbin/nologin mysql
[[email protected] mysql]# ls bin COPYING docs include lib man README share support-files [[email protected] mysql]# mkdir -p /usr/local/mysql/data/mysql [[email protected] mysql]# chown mysql /usr/local/mysql/data/mysql
下面這步註意最後一句：
[[email protected] mysql]# ./bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data/mysql 2017-09-27T03:44:47.999985Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2017-09-27T03:44:49.011240Z 0 [Warning] InnoDB: New log files created, LSN=45790 2017-09-27T03:44:49.180334Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2017-09-27T03:44:49.245777Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 3649ce8c-a336-11e7-a43f-000c292b2832. 2017-09-27T03:44:49.266053Z 0 [Warning] Gtid table is not ready to be used. Table ‘mysql.gtid_executed‘ cannot be opened. 2017-09-27T03:44:49.268172Z 1 [Note] A temporary password is generated for [email protected]: ADB&yGx-d8ab
ADB&yGx-d8ab 是密碼
接著執行：
[[email protected] mysql]# ./bin/mysql_ssl_rsa_setup --datadir=usr/local/mysql/data/mysql Generating a 2048 bit RSA private key ......................+++ ...+++ writing new private key to ‘ca-key.pem‘ ----- Generating a 2048 bit RSA private key .........................+++ ...............................................................................+++ writing new private key to ‘server-key.pem‘ ----- Generating a 2048 bit RSA private key ....................+++ .......................+++ writing new private key to ‘client-key.pem‘
4. 拷貝配置文件和啟動腳本
先檢查是否有/etc/my.cnf,如果沒有
cp support-files/my-default.cnf /etc/my.cnf
編輯/etc/my.cnf,重點修改下面幾個，其他的盡量註釋掉：
basedir = /usr/local/mysql datadir = //usr/local/mysql/data/mysql socket = /tmp/mysql.sock
2.啟動腳本
cp support-files/mysql.server /etc/init.d/mysqld
編輯/etc/init.d/mysqld，只修改下面幾個：
basedir=/usr/local/mysql datadir=/data/mysql
將/etc/init.d/mysqld加入啟動項：
[[email protected] mysql]# chkconfig --add mysqld
[[email protected] mysql]# chkconfig --list
註意：該輸出結果只顯示 SysV 服務，並不包含原生 systemd 服務。SysV 配置數據可能被原生 systemd 配置覆蓋。
如果您想列出 systemd 服務,請執行 ‘systemctl list-unit-files‘。
欲查看對特定 target 啟用的服務請執行
‘systemctl list-dependencies [target]‘。
mysqld 0:關 1:關 2:開 3:開 4:開 5:開 6:關
netconsole 0:關 1:關 2:關 3:關 4:關 5:關 6:關
network 0:關 1:關 2:開 3:開 4:開 5:開 6:關5. 啟動服務
/etc/init.d/mysqld start
6.設置root密碼
用初始密碼登陸（見上面第3步）
/usr/local/mysql/bin/mysql -uroot -p‘初始密碼’ #-p和’’不能隔開
出現mysql>的時候，輸入set password = password(‘新密碼‘)；
退出，用新密碼登陸
2. 忘記初始密碼
給/etc/my.cnf/[mysqld]下面增加一行skip-grant-tables,重啟 mysqld：/etc/init.d/mysqld restart
[mysqld] skip-grant-tables basedir=/usr/local/mysql datadir=/usr/local/mysql/data/mysql socket=/tmp/mysql.sock [[email protected] ~]# /etc/init.d/mysqld restart Shutting down MySQL.. SUCCESS! Starting MySQL.. SUCCESS!
重新登錄 mysql：
[[email protected] ~]# /usr/local/mysql/bin/mysql -uroot
mysql>後輸入：update mysql.user set authentication_string=password(‘123333‘) where user=‘root‘;
mysql> update mysql.user set authentication_string=password(‘123333‘) where user=‘root‘; Query OK, 1 row affected, 1 warning (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 1
退出，刪除 my.cnf 加入的skip-grant-tables，重啟mysqld
新密碼重新登錄 mysql：
[[email protected] ~]# /usr/local/mysql/bin/mysql -uroot -p‘123333‘ mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor.
