CentOs7 急速安裝 MySQL

CentOs7 急速安裝 MySQL，獻給還在爲裝機浪費生命的同窗。

準備工做：

Centos7 最小化安裝（或者更高）

Oracle 官網下載 MySQL 安裝包 (https://dev.mysql.com/downloads/mysql/)

這裏演示安裝 5.6 版本, 下載的包爲 MySQL-5.6.37-1.el7.x86_64.rpm-bundle.tar

開始：

把文件上傳到服務器，我這是上傳到 /root/ 路徑，mysql 版本爲 5.6.37

[root@localhost ~]# ll
total 237944
-rw-------. 1 root root      1320 Aug 14 13:48 anaconda-ks.cfg
-rwxr-xr-x. 1 root root 243650560 Aug 14 14:28 MySQL-5.6.37-1.el7.x86_64.rpm-bundle.tar
[root@localhost ~]#

登錄到服務器新建一個腳本文件

vi mysql_secure_installation.exp

將如下內容複製到腳本文件， 輸入 :wq 退出

#!/usr/bin/expect

set pwd [lindex $argv 0]

spawn /usr/bin/mysql_secure_installation

expect {
  "none\):" { send "$pwd\r" }
}
expect {
  "*Y/n*" { send "y\r" }
}
expect {
  "password:" { send "123456\r" }
}
expect {
  "password:" { send "123456\r" }
}
expect {
  "*Y/n*" { send "y\r" }
}
expect {
  "*Y/n*" { send "n\r" }
}
expect {
  "*Y/n*" { send "y\r" }
}
expect {
  "*Y/n*" { send "y\r" }
}
expect {
  "*Y/n*" { send "y\r" }
}

這裏設置 mysql 的默認密碼爲 123456， 也能夠改成其餘的。

接下來執行安裝

export MYSQL_VERSION=5.6.37-1.el7.x86_64 && \
yum install -y expect && \
yum install -y libaio.x86_64 && \
yum install -y perl perl-devel perl-Data-Dumper && \
rpm -qa|grep -i mysql|xargs rpm -e --nodeps|date && \
rpm -qa|grep -i mariadb|xargs rpm -e --nodeps|date && \
rm -rf /etc/my.cnf && \
rm -rf /usr/my.cnf && \
rm -rf /var/log/mysql && \
tar -xvf MySQL-$MYSQL_VERSION.rpm-bundle.tar && \
rpm -ivh MySQL-server-$MYSQL_VERSION.rpm && \
rpm -ivh MySQL-devel-$MYSQL_VERSION.rpm && \
rpm -ivh MySQL-client-$MYSQL_VERSION.rpm && \
mysql_install_db --user=mysql && \
service mysql start && \
expect mysql_secure_installation.exp `cat /root/.mysql_secret | awk -F '):' '{print $2}'|sed s/[[:space:]]//g` && \
cp /usr/share/mysql/my-default.cnf /etc/my.cnf && \
echo 'port=3306' >> /etc/my.cnf && \
echo 'max_allowed_packet=1G' >> /etc/my.cnf && \
echo 'default-storage-engine=innodb' >> /etc/my.cnf && \
echo 'character_set_server=utf8' >> /etc/my.cnf && \
echo 'innodb_strict_mode=0' >> /etc/my.cnf && \
echo 'lower_case_table_names=1' >> /etc/my.cnf && \
service mysql restart && \
mysql -uroot -p123456 -e "grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;";

第一行 MYSQL_VERSION 改成當前 mysql 的版本。

在命令行輸入 mysql --version

[root@localhost ~]# mysql --version
mysql  Ver 14.14 Distrib 5.6.37, for Linux (x86_64) using  EditLine wrapper

這裏爲了方便演示遠程鏈接先將防火牆關閉

systemctl stop firewalld && setenforce 0;

查看 ip

[root@localhost ~]# ifconfig 
enp0s3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.0.33  netmask 255.255.254.0  broadcast 192.168.1.255
        inet6 fe80::386e:65ac:d4eb:679  prefixlen 64  scopeid 0x20<link>

使用 mysql 客戶端遠程鏈接數據庫， 默認密碼爲 123456

bingaos-MacBook-Pro:Downloads bingao$ mysql -h192.168.0.33 -uroot -p
Enter password:

鏈接成功。

 

解釋如下作了什麼事情：

使用yum安裝了 expect libaio.x86_64 perl perl-devel perl-Data-Dumper

檢查系統是否有安裝過 mysql 若是有就刪除

刪除系統自帶的 mariadb

刪除 /etc/my.cnf /usr/my.cnf 配置文件

刪除 默認數據 /var/log/mysql

rpm 安裝 MySQL-server-5.6.37-1.el7.x86_64.rpm

rpm 安裝 MySQL-devel-5.6.37-1.el7.x86_64.rpm

rpm 安裝 MySQL-client-5.6.37-1.el7.x86_64.rpm

使用 mysql_install_db --user=mysql 命令初始化數據庫

使用 /usr/bin/mysql_secure_installation 初始化數據庫配置

新建了 /etc/my.cnf， 增長了幾個參數 （這裏能夠根據我的須要修改）

max_allowed_packet=1G

default-storage-engine=innodb 

character_set_server=utf8 

innodb_strict_mode=0 

lower_case_table_names=1
