這篇文章給大家分享的是有關(guān)CentOS7如何安裝mysql5.7解壓縮版的內(nèi)容。小編覺得挺實(shí)用的,因此分享給大家做個(gè)參考,一起跟隨小編過來看看吧。
1.下載安裝包
http://dev.mysql.com/downloads/mysql/#downloads
2.檢查庫文件是否存在,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組和用戶是否存在,如無創(chuàng)建。
[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 以上為默認(rèn)存在的情況,如無,執(zhí)行添加命令: [root@localhost ~]$groupadd mysql [root@localhost ~]$useradd -r -g mysql mysql //useradd -r參數(shù)表示mysql用戶是系統(tǒng)用戶,不可用于登錄系統(tǒng)。
4.解壓TAR包,更改所屬的組和用戶
[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.安裝和初始化數(shù)據(jù)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)
如果改變默認(rèn)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)創(chuàng)建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(shè)置開機(jī)啟動(dòng) [root@localhost bin]$ chkconfig --level 35 mysqld on [root@localhost bin]$
6.初始化密碼
mysql5.7會(huì)生成一個(gè)初始化密碼,而在之前的版本首次登陸不需要登錄。
[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.添加遠(yuǎn)程訪問權(quán)限
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(huì)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
連接Mysql時(shí),機(jī)器上找不到mysql.sock文件你可以簡單地通過重啟服務(wù)器重新創(chuàng)建得到它。因?yàn)榉?wù)器在啟動(dòng)時(shí)重新創(chuàng)建它。
[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(在非默認(rèn)目錄時(shí)需要指定,默認(rèn)路徑:/usr/local/mysql,同時(shí)需要指定./support-files/mysql.server中的basedir和datadir為相應(yīng)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(bào)錯(cuò)均因未在mysql.server中指定自定義的路徑。
若是還提示已經(jīng)有data文件了 刪除了它,新建即可
