mysql 开发进阶篇种类 2玖 数据库二进制包安装

概述  

  对于贰进制安装,优点是足以设置到别的路径下,灵活性好,壹台服务器能够设置八个mysql。缺点是现已绎过编写翻译,质量不及源码编写翻译得好,无法灵活定制编写翻译参数。要是用户即不想安装最简便却不够灵活的奥迪Q5PM包,又不想安装复杂费时的源码包,那么已编写翻译好的二进制包将是最棒的选项。

一.步骤1: 解压glib包

-- 在 /usr/local 下创建一个mysql文件夹,用来存放
[root@hsr local]# mkdir mysql
[root@hsr local]# ls
bin  etc  games  include  lib  lib64  libexec  mysql  sbin  share  src

-- 在原有/usr/tool目录将gz压缩包解压
[root@hsr tool]# tar -zxvf mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz
mysql-5.7.23-linux-glibc2.12-x86_64/bin/myisam_ftdump
mysql-5.7.23-linux-glibc2.12-x86_64/bin/myisamchk
mysql-5.7.23-linux-glibc2.12-x86_64/bin/myisamlog
mysql-5.7.23-linux-glibc2.12-x86_64/bin/myisampack
mysql-5.7.23-linux-glibc2.12-x86_64/bin/mysql
mysql-5.7.23-linux-glibc2.12-x86_64/bin/mysql_client_test_embedded
mysql-5.7.23-linux-glibc2.12-x86_64/bin/mysql_config_editor
.....

--将解压的文件复制到/usr/local/mysql目录下
[root@hsr tool]# sudo cp -r mysql-5.7.23-linux-glibc2.12-x86_64 /usr/local/mysql

--在mysql-->mysql-5.7.23-linux-glibc2.12-x86_64路径下 解压的文件共9个 目录如下: 
[root@hsr mysql]# ls mysql-5.7.23-linux-glibc2.12-x86_64 bin COPYING docs include lib man README share support-files

  注意:mysql-5.7.23-linux-glibc2.12-x86_6四目录层次要去掉,变为/usr/local/mysql
下的九个目录,在文章后边会去掉那层。

二. 步骤2:    

   2.1 添加mysql用户 useradd -r -g 用户名 用户组

[root@hsr mysql]# groupadd mysql
[root@hsr mysql]# useradd -r -g mysql mysql

  2.二 切换成 /usr/local/mysql 目录下,改变目录拥有者为mysql

[root@hsr mysql]# chown -R  mysql.mysql /usr/local/mysql

  二.三 新环境安装libaio包 mysql 信赖于libaio

[root@hsr mysqld]# yum search libaio

三 步骤3:  

  安装mysql,使用 –initialize,basedir
基础目录,datadir 为数据目录。

[root@hsr ~]# cd /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/bin
[root@hsr bin]# ./mysqld  --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
2018-08-23T06:56:21.157088Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2018-08-23T06:56:21.157246Z 0 [ERROR] Can't find error-message file '/usr/local/mysql/share/errmsg.sys'. Check error-message file location and 'lc-messages-dir' configuration directive.
2018-08-23T06:56:26.287087Z 0 [Warning] InnoDB: New log files created, LSN=45790
2018-08-23T06:56:27.059913Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2018-08-23T06:56:27.138616Z 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: a7e28575-a6a1-11e8-af13-000c29affb65.
2018-08-23T06:56:27.154064Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
2018-08-23T06:56:27.155635Z 1 [Note] A temporary password is generated for root@localhost: ro0ssOGT?ocf

四步骤4:

  4.1 创建RSA
private key。

[root@hsr bin]# bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data

  图片 2

  肆.二 修改当前目录拥有者为 root 用户,修改data 目录拥有者为 mysql

[root@hsr bin]# chown -R root:root /usr/local/mysql
[root@hsr bin]# chown -R mysql:mysql /usr/local/mysql/data

 五.步骤5 配置mysql(mysql.server)和my.cnf文件

--检查 etc/my.cnf文件是否存在 (二进制安装,默认配置文件在/etc/my.cnf)
    [root@hsr etc]# find -name  my.cnf
    ./my.cnf

 --将support-files 目录下的mysql.server文件复制到etc/init.d下
    [root@hsr ~]# cd /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/support-files
    [root@hsr support-files]# cp mysql.server /etc/init.d/mysql

 -- 配置/etc/init.d/mysql服务文件 添加basedir和datadir
    [root@hsr support-files]# vim /etc/init.d/mysql

    图片 3

   修改my.cnf  配置以下多个参数(只顾:chkconfig — level 3伍 mysqld on
不要加上,后面报错,又得去掉
)
    图片 4

 六.步骤6 启动mysql

[root@hsr bin]# service mysql start
/etc/init.d/mysql: line 239: my_print_defaults: command not found
    Starting MySQL ERROR! Couldn't find MySQL server (/usr/local/mysql/bin/mysqld_safe) 

--提示未找到路径,需要把"mysql-5.7.23-linux-glibc2.12-x86_64" 文件夹去掉,使用mv 将里面的文件移到/usr/locl/mysql下,共9个文件
[root@hsr bin]# mv /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/README /usr/local/mysql
[root@hsr bin]# mv /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/COPYING /usr/local/mysql
[root@hsr bin]# mv /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/support-files /usr/local/mysql
[root@hsr bin]# mv /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/share /usr/local/mysql
[root@hsr bin]# mv /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/man /usr/local/mysql
[root@hsr bin]# mv /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/lib /usr/local/mysql
[root@hsr bin]# mv /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/include /usr/local/mysql
[root@hsr bin]# mv /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/docs /usr/local/mysql
[root@hsr bin]# mv /usr/local/mysql/mysql-5.7.23-linux-glibc2.12-x86_64/bin /usr/local/mysql

-- 再启动
[root@hsr bin]# service mysql start
Starting MySQL.2018-08-24T01:06:20.545225Z mysqld_safe error: log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.
 ERROR! The server quit without updating PID file (/usr/local/mysql/data/hsr.pid).

-- 提示/var/log/mariadb/mariadb.log 不存在, 打开my.cnf 能看到定义的默认路径
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

--创建目录 给权限
[root@hsr bin]# mkdir /var/log/mariadb 
[root@hsr bin]# touch /var/log/mariadb/mariadb.log 
[root@hsr bin]# chown -R mysql:mysql  /var/log/mariadb/

-- 再启动
[root@hsr bin]# service mysql start
Starting MySQL.... ERROR! The server quit without updating PID file (/usr/local/mysql/data/hsr.pid).

-- 错误信息是hsr.pid进程出问题,先查看下日志
[root@hsr ~]# cat /var/log/mariadb/mariadb.log

  图片 5
   在my.cnf中注释上边参数(#chkconfig –level 35 mysqld on),再启动
  图片 6
  上海体育场面意思是不能够创建mysql.sock.lock
文件,一般是权力不足,如下设置好权力,运营成功
  图片 7

七 登录mysql

[root@hsr ~]# mysql -u root -p
bash: mysql: 未找到命令

  未找到命令,是出于系统私下认可会查找/usr/bin下的授命,若是这么些命令不在这些目录下,就会找不到命令,必要映射一个链接到/usr/bin目录下,也便是建立多少个链接文件。

[root@hsr ~]#  ln -s /usr/local/mysql/bin/mysql /usr/bin
[root@hsr ~]# mysql -u -root -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

--错误信息是不能连接到本地的socket ,系统默认找到了/tmp目录下,需要设置链接文件
[root@hsr tmp]# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

[root@hsr ~]# mysql -u -root -p
Enter password:

 八. 设置密码  

  8.一 打开my.cnf文件,添加skip-grant-tables,来重置密码,如下所示
    图片 8
  八.二 运行服务,再度登录,在输入密码处按回车键进入。

[root@hsr ~]# vim /etc/my.cnf
[root@hsr ~]# service mysql restart
Shutting down MySQL.. SUCCESS! 
Starting MySQL. SUCCESS! 
[root@hsr ~]# mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.7.23

  八.叁 进入mysql后,修改密码

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed

mysql> update user set authentication_string=password('123456') where user='root';
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 1

  退出mysql>quit;  编辑 my.cnf 注释掉#skip-grant-tables

 8.四 重启mysql服务,输入修改后的密码(12345陆)进入

[root@hsr ~]# service mysql restart
Shutting down MySQL.. SUCCESS! 
Starting MySQL. SUCCESS! 
[root@hsr ~]# mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.7.23

 9 远程登录

-- 登录到mysql后设置权限
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; 
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
--  再设置密码
mysql> SET PASSWORD = PASSWORD('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)
-- 设置权限
mysql> ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.00 sec)
-- 刷新权限 
mysql>  flush privileges;
Query OK, 0 rows affected (0.01 sec)
-- 设置远程登录权限
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; 
Query OK, 0 rows affected, 1 warning (0.00 sec)

  – 在my.cnf中 添加端口,重启服务
  图片 9

-- 测试端口是否打开
[root@hsr ~]#  firewall-cmd    --query-port=3306/tcp
no
-- 防火墙设置
[root@hsr ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
-- 重新加载
[root@hsr ~]# firewall-cmd --reload
success
-- 再次测试端口
[root@hsr ~]# firewall-cmd    --query-port=3306/tcp
yes

  – 在windows端拼通成功
