Linux安裝mysql5.7

  搭建服務器第一步:安裝數據庫html

 我這裏選擇的是比較通用的mysql,知足大部分的市場需求了。mysql

  首先準備好mysql壓縮包Xshell和Xftp這裏給個地址:https://pan.baidu.com/s/1DHZaroNWV78TYnob5kOTgglinux

一、在上面的連接下載tar包,或者使用wget從官網下載
sql

  wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gzshell

二、將mysql安裝到/usr/local/mysql下數據庫

  # 解壓bootstrap

  tar -xvf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz服務器

  # 移動socket

  mv mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/ide

  # 重命名

  mv /usr/local/mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/mysql

三、新建data目錄

  mkdir /usr/local/mysql/data

四、新建mysql用戶、mysql用戶組

  # mysql用戶組

  groupadd mysql

  # mysql用戶

  useradd mysql -g mysql

五、將/usr/local/mysql的全部者及所屬組改成mysql

  chown -R mysql.mysql /usr/local/mysql

六、配置

  /usr/local/mysql/bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data

  # 若是出現如下錯誤:

2018-07-14 06:40:32 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2018-07-14 06:40:32 [ERROR]   Child process: /usr/local/mysql/bin/mysqldterminated prematurely with errno= 32
2018-07-14 06:40:32 [ERROR]   Failed to execute /usr/local/mysql/bin/mysqld --bootstrap --datadir=/usr/local/mysql/data --lc-messages-dir=/usr/local/mysql/share --lc-messages=en_US --basedir=/usr/local/mysql
-- server log begin --

-- server log end --

  # 則使用如下命令:

/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize

  # 若是出現如下錯誤:

/usr/local/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

  # 則執行如下命令:

  yum -y install numactl

  # 完成後繼續安裝:

/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize

  # 編輯/etc/my.cnf

[mysqld]
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
socket=/tmp/mysql.sock
user=mysql
port=3306
character-set-server=utf8
# 取消密碼驗證
skip-grant-tables
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# skip-grant-tables
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

  七、開啓服務

  # 將mysql加入服務

  cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

  # 開機自啓

  chkconfig mysql on

  # 開啓

  service mysql start

  八、設置密碼

  # 登陸(因爲/etc/my.cnf中設置了取消密碼驗證,因此此處密碼任意)

  /usr/local/mysql/bin/mysql -u root -p

  # 操做mysql數據庫

  >>use mysql;

  # 修改密碼

  >>update user set authentication_string=password('你的密碼') where user='root';

  >>flush privileges;

  >>exit;

  九、將/etc/my.cnf中的skip-grant-tables刪除

  十、登陸再次設置密碼(不知道爲啥若是再也不次設置密碼就操做不了數據庫了)

  /usr/local/mysql/bin/mysql -u root -p

   >>ALTER USER 'root'@'localhost' IDENTIFIED BY '修改後的密碼';

  >>exit;

  十一、容許遠程鏈接

  /usr/local/mysql/bin/mysql -u root -p

  >>use mysql;

  >>update user set host='%' where user = 'root';

  >>flush privileges;

  >>eixt;

  十二、添加快捷方式

  ln -s /usr/local/mysql/bin/mysql /usr/bin
