centos7安裝mysql5.7筆記

一、首先安裝依賴包,避免在安裝過程當中出現問題mysql

# yum install gcc gcc-c++ kernel-devel ncurses-devel bison cmake
# tar -zxvf boost_1_62_0.tar.gz  
# cp -r /opt/soft/boost_1_62_0 /usr/local/boost


二、建立mysql用戶及用戶組c++

# groupadd mysql
# useradd -g mysql mysql


三、安裝mysqlsql

# tar zxvf mysql-5.7.16.tar.gz
# cd mysql-5.7.16
# cmake . -DCMAKE_INSTALL_PREFIX=/opt/mysql-5.7.16 -DMYSQL_DATADIR=/data/mysqldata -DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_BOOST=/usr/local/boost
# make
# make install


CMAKE參數說明:
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql //默認安裝目錄
-DINSTALL_DATADIR=/usr/local/mysql/data //數據庫存放目錄
-DDEFAULT_CHARSET=utf8 //使用utf8字符
-DDEFAULT_COLLATION=utf8_general_ci //校驗字符
-DEXTRA_CHARSETS=all //安裝全部擴展字符集
-DENABLED_LOCAL_INFILE=1 //容許從本地導入數據
-DMYSQL_USER=mysql
-DMYSQL_TCP_PORT=3306
注意事項:
如安裝失敗從新編譯時,須要清除舊的對象文件和緩存信息。數據庫

# make clean
# rm -f CMakeCache.txt
# rm -rf /etc/my.cnf


四、設置目錄權限並初始化數據庫緩存

# chown -R mysql.mysql /opt/mysql-5.7.16
# cp /opt/mysql-5.7.16/support-files/my-default.cnf /etc/my.cnf                           
# cp /opt/mysql-5.7.16/support-files/mysql.server /etc/rc.d/init.d/mysqld(將mysql的啓動服務添加到系統服務中)
# /opt/mysql-5.7.16/bin/mysqld --initialize --user=mysql --basedir=/opt/mysql-5.7.16 --datadir=/data/mysqldata(初始化數據庫)


五、開啓mysql服務bash

# service mysqld start
# chkconfig --add mysqld(加入開機啓動服務)
# chkconfig mysqld on


七、登錄修改root密碼服務器

# /opt/mysql-5.7.16/bin/mysql -uroot -p(鏈接mysql,輸入初始化時生成的隨機密碼)
mysql>alter user 'root'@'localhost' identified by 'abc123';


八、修改MySQL的root用戶密碼和受權用戶管理某個數據庫網絡

grant all on db_book.* to jack@'%' identified by 'abc123';(新建用戶帳號和密碼並受權用戶來管理某個數據庫)
 flush privileges;
 exit
 \s  (查看服務器狀態)


#mysql的一些簡單命令:
show databases;
 use database;
show tables;
create database lufee;
create table users(userid varchar(8),username varchar(8));
 insert into users values('001','zhen');
insert into users values('002','jack');
select * from users;
desc users;

備份:/opt/mysql/bin/mysqldump -uroot -p密碼 數據庫名 > data.bak
恢復:/opt/mysql/bin/mysql -uroot -p密碼 數據庫名 < data.bakdom

 

120726 11:57:22 [Warning] 'user' entry '@localhost.localdomain' ignored in --skip-name-resolve mode.
skip-name-resolve是禁用dns解析,避免網絡DNS解析服務引起訪問MYSQL的錯誤,通常應當啓用。
啓用後,在mysql的受權表中就不能使用主機名了,只能使用IP ,出現此警告是因爲mysql 表中已經存在有 localhost.localdomain 賬號信息。
 咱們把它刪除就行了。socket

use mysql;
delete from user where HOST='localhost.localdomain';


 Query OK, 2 rows affected (0.00 sec)
重啓MYSQL ,發現警告已經沒有啦。

數據庫配置文件/etc/my.cnf 參考內容:
