LNMP架構二(Mysql資料庫安裝)
二、Mysql資料庫安裝
1、下載mysql二進位制包
[[email protected] src]# wget http://mirrors.163.com/mysql/Downloads/MySQL-5.7/mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz
2、解壓縮
[[email protected] src]# tar -zxvf mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz
[[email protected] src]# mv mysql-5.7.23-linux-glibc2.12-x86_64 /usr/local/mysql
3、修改配置檔案
vi /etc/my,cnf
[mysqld]
port=3306
character-set-server=utf8
basedir=/usr/local/mysql
datadir=/data
#innodb_buffer_pool_size=8M[mysqld_safe]
log-error=/data/error.log
pid-file=/data/mysql.pid
tmpdir = /tmp
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
4、建立使用者及使用者組
新增mysql使用者組
#groupadd mysql
給mysql組下新增mysql使用者
#useradd -r -g mysql -s /sbin/nologin mysql
改變檔案所有者和所屬組
#chown -R mysql /usr/local/mysql/
#chgrp -R mysql /usr/local/mysql/
5、解除安裝mariadb
#列出所有被安裝的rpm package
# rpm -qa | grep maria*
mariadb-libs-5.5.56-2.el7.x86_64
# yum -y remove mari*
已載入外掛:fastestmirror
正在解決依賴關係
--> 正在檢查事務
---> 軟體包 mariadb-libs.x86_64.1.5.5.56-2.el7 將被 刪除
......
...
刪除:
mariadb-libs.x86_64 1:5.5.56-2.el7作為依賴被刪除:
postfix.x86_64 2:2.10.1-6.el7完畢!
# rm -rf /var/lib/mysql/*
6、將mysql放入系統服務,並修改對應檔案
[[email protected] support-files]# cp mysql.server /etc/init.d/mysqld
7、初始化安裝
yum install libaio -y
[[email protected] /]# mkdir /data
[[email protected] /]# chown -R mysql:mysql /data
[[email protected] bin]# ./mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data
出現上圖,說明已經安裝成功!
8、啟動mysql
[[email protected] bin]# service mysqld start
9、登陸mysql並輸入5.7初始化時列印的密碼:
10、修改root密碼
mysql>SET PASSWORD FOR 'root'@localhost=PASSWORD('123456');
11、設定root允許遠端連線
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 -ADatabase changed
mysql> update user set host='%' where user='root' limit 1;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
12、mysql加入環境變數並設定mysql為自啟服務
[[email protected] bin]# vi /etc/profile
新增到最後
export MYSQL_HOME=/usr/local/mysql
export PATH=$MYSQL_HOME/bin:$PATH
[[email protected] bin]# source /etc/profile (立即生效)
[[email protected] bin]# chmod +x /etc/rc.d/init.d/mysqld (新增可執行許可權)
[[email protected] bin]# chkconfig --add mysqld (新增到開機自啟)
