CentOS7安裝mysql5.7解壓縮版簡明教程
阿新 • • 發佈:2020-01-09
本文例項講述了CentOS7安裝mysql5.7解壓縮版的方法。分享給大家供大家參考,具體如下:
1.下載安裝包
http://dev.mysql.com/downloads/mysql/#downloads
推薦下載通用安裝方法的TAR包
2.檢查庫檔案是否存在,如有刪除。
[root@localhost Desktop]$ rpm -qa | grep mysql mysql-libs-5.1.52-1.el6_0.1.x86_64 [root@localhost ~]$ rpm -e mysql-libs-5.1.52.x86_64 --nodeps [root@localhost ~]$
3.檢查mysql組和使用者是否存在,如無建立。
[root@localhost ~]$ cat /etc/group | grep mysql mysql:x:490: [root@localhost ~]$ cat /etc/passwd | grep mysql mysql:x:496:490::/home/mysql:/bin/bash 以上為預設存在的情況,如無,執行新增命令: [root@localhost ~]$groupadd mysql [root@localhost ~]$useradd -r -g mysql mysql //useradd -r引數表示mysql使用者是系統使用者,不可用於登入系統。
4.解壓TAR包,更改所屬的組和使用者
[root@localhost ~]$ cd /usr/local/ [root@localhost local]$ tar xvf mysql-5.7.12-linux-glibc2.5-x86_64.tar [root@localhost local]$ ls -l total 1306432 -rwxr--r--. 1 root root 668866560 Jun 1 15:07 mysql-5.7.12-linux-glibc2.5-x86_64.tar -rw-r--r--. 1 7161 wheel 638960236 Mar 28 12:54 mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz -rw-r--r--. 1 7161 wheel 29903372 Mar 28 12:48 mysql-test-5.7.12-linux-glibc2.5-x86_64.tar.gz [root@localhost local]$ tar xvfz mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz [root@localhost local]$ mv mysql-5.7.12-linux-glibc2.5-x86_64 mysql [root@localhost local]$ ls -l total 1306436 drwxr-xr-x. 2 root root 4096 Dec 4 2009 bin drwxr-xr-x. 2 root root 4096 Dec 4 2009 etc drwxr-xr-x. 2 root root 4096 Dec 4 2009 games drwxr-xr-x. 2 root root 4096 Dec 4 2009 include drwxr-xr-x. 2 root root 4096 Dec 4 2009 lib drwxr-xr-x. 3 root root 4096 Dec 2 14:36 lib64 drwxr-xr-x. 2 root root 4096 Dec 4 2009 libexec drwxr-xr-x. 9 7161 wheel 4096 Mar 28 12:51 mysql -rwxr--r--. 1 root root 668866560 Jun 1 15:07 mysql-5.7.12-linux-glibc2.5-x86_64.tar -rw-r--r--. 1 7161 wheel 638960236 Mar 28 12:54 mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz -rw-r--r--. 1 7161 wheel 29903372 Mar 28 12:48 mysql-test-5.7.12-linux-glibc2.5-x86_64.tar.gz drwxr-xr-x. 2 root root 4096 Dec 4 2009 sbin drwxr-xr-x. 6 root root 4096 Dec 2 14:36 share drwxr-xr-x. 2 root root 4096 Dec 4 2009 src [root@localhost local]$ chown -R mysql mysql/ [root@localhost local]$ chgrp -R mysql mysql/ [root@localhost local]$ cd mysql/
5.安裝和初始化資料庫
[root@localhost mysql]$ bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ 2016-06-01 15:23:25 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize 2016-06-01 15:23:30 [WARNING] The bootstrap log isn't empty: 2016-06-01 15:23:30 [WARNING] 2016-06-01T22:23:25.491840Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead 2016-06-01T22:23:25.492256Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000) 2016-06-01T22:23:25.492260Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)
如果改變預設安裝路徑,則需要 1)/etc/my.cnf、/etc/init.d/mysqld中修改 basedir='/apps/mysql' datadir='/apps/mysql/data' 2)建立ln mkdir -p /usr/local/mysql/bin ln -s /apps/mysql/bin/mysqld /usr/local/mysql/bin/mysqld
[root@localhost mysql]$ [root@localhost mysql]$ cp -a ./support-files/my-default.cnf /etc/my.cnf [root@localhost mysql]$ cp -a ./support-files/mysql.server /etc/init.d/mysqld [root@localhost mysql]$ cd bin/ [root@localhost bin]# ./mysqld_safe --user=mysql & [1] 2932 [root@localhost bin]# 2016-06-01T22:27:09.708557Z mysqld_safe Logging to '/usr/local/mysql/data/localhost.localdomain.err'. 2016-06-01T22:27:09.854913Z mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data [root@localhost bin]# /etc/init.d/mysqld restart Shutting down MySQL..2016-06-01T22:27:50.498694Z mysqld_safe mysqld from pid file /usr/local/mysql/data/localhost.localdomain.pid ended SUCCESS! Starting MySQL. SUCCESS! [1]+ Done ./mysqld_safe --user=mysql [root@localhost bin]$ //設定開機啟動 [root@localhost bin]$ chkconfig --level 35 mysqld on [root@localhost bin]$
6.初始化密碼
mysql5.7會生成一個初始化密碼,而在之前的版本首次登陸不需要登入。
[root@localhost bin]$ cat /root/.mysql_secret # Password set for user 'root@localhost' at 2016-06-01 15:23:25,xxxxxR5H9 [root@localhost bin]$./mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.12 Copyright (c) 2000,2016,Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> SET PASSWORD = PASSWORD('123456'); Query OK,0 rows affected,1 warning (0.00 sec) mysql> flush privileges; Query OK,0 rows affected (0.00 sec)
7.新增遠端訪問許可權
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 host = '%' where user = 'root'; Query OK,1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> select host,user from user; +-----------+-----------+ | host | user | +-----------+-----------+ | % | root | | localhost | mysql.sys | +-----------+-----------+ //一定要重啟才會生效。 /etc/init.d/mysqld restart
遇到的問題:
找不到mysql.sock,mysql.sock丟失問題解決方法
連線Mysql時,機器上找不到mysql.sock檔案你可以簡單地通過重啟伺服器重新建立得到它。因為伺服器在啟動時重新建立它。
[root@localhost mysql-5.7.13]# ./bin/mysql_install_db --user=mysql 2016-06-26 02:47:09 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize 2016-06-26 02:47:09 [ERROR] The data directory needs to be specified.
解決:需要新建data目錄,指定安裝目錄(在非預設目錄時需要指定,預設路徑:/usr/local/mysql,同時需要指定./support-files/mysql.server中的basedir和datadir為相應路徑)。
[root@localhost mysql-5.7.13]# ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql-5.7.13/ --datadir=/usr/local/mysql-5.7.13/data/ 2016-06-26 02:48:47 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize 2016-06-26 02:49:19 [WARNING] The bootstrap log isn't empty: 2016-06-26 02:49:19 [WARNING] 2016-06-26T09:48:50.798592Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead 2016-06-26T09:48:50.898732Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000) 2016-06-26T09:48:50.898778Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)
以上報錯均因未在mysql.server中指定自定義的路徑。
若是還提示已經有data檔案了 刪除了它,新建即可
希望本文所述對大家CentOS伺服器維護有所幫助。
