Centos7 - mysql 5.5.62 tar.gz 方式安裝

安裝準備

Mariadb 去除

因爲CentOS7自帶的是 Mariadb, 因此先來刪除他吧...

1. 查找版本

# rpm -qa|grep mariadb

執行命令後會出現相似 MariaDB-server-5.5.49-1.el7.centos.x86_64 之類的鬼..記住名字就好了.

2. 刪除

# rpm -e --nodeps 上面查出來的文件名

3. 刪除配置文件

# rm /etc/my.cnf

安裝包獲取

在官方直接找吧 　　MySQL Community Server 5.5.62

選擇 Linux - Generic 注意

推送壓縮包

推送到虛擬機或者遠程服務器, ftp 或者  rz, 或者直接圖形界面拖動隨你, 總之推上去就好了

開始安裝

解壓

解壓中注意若是出現EOF 報錯之類的須要考慮是否壓縮包文件損壞

嘗試更換壓縮包或者從新推送壓縮包

tar -xvf mysql-5.5.62-linux-glibc2.12-x86_64.tar.gz

複製到 local 

mv mysql-5.5.62-linux-glibc2.12-x86_64 /usr/local

修改文件夾

cd /usr/local
mv mysql-5.5.62-linux-glibc2.12-x86_64 mysql-5.5.62

 修改配置文件

vi /etc/my.cnf

[mysql]
# 設置mysql客戶端默認字符集
default-character-set=utf8 
socket=/var/lib/mysql/mysql.sock

[mysqld]
skip-name-resolve
#設置3306端口
port = 3306 

socket=/var/lib/mysql/mysql.sock
# 設置mysql的安裝目錄, 這裏的目錄必定要是你解壓後而且改了名的目錄喲..

basedir=/usr/local/mysql-5.5.62
# 設置mysql數據庫的數據的存放目錄, 這裏的目錄必定要是你解壓後而且改了名的目錄喲..

datadir=/usr/local/mysql-5.5.62/data

# 容許最大鏈接數
max_connections=200

# 服務端使用的字符集默認爲8比特編碼的latin1字符集
character-set-server=utf8

# 建立新表時將使用的默認存儲引擎
default-storage-engine=INNODB

lower_case_table_name=1
max_allowed_packet=16M

切換目錄到mysql中

cd /usr/local/mysql-5.5.62

添加用戶組與用戶

注意 : 這裏須要將目錄切換到mysql目錄下 也就是上一步的操做

groupadd mysql

useradd -g mysql mysql

chown -R mysql:mysql ./

安裝mysql

./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql-5.5.62/ --datadir=/usr/local/mysql-5.5.62/data/

 安裝後會有以下的打印

[root@yangtuo mysql-5.5.62]# ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql-5.5.62/ --datadir=/usr/local/mysql-5.5.62/data/

OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/local/mysql-5.5.62//bin/mysqladmin -u root password 'new-password'
/usr/local/mysql-5.5.62//bin/mysqladmin -u root -h 172.20.10.7
192.168.122.1 password 'new-password'

Alternatively you can run:
/usr/local/mysql-5.5.62//bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr/local/mysql-5.5.62/ ; /usr/local/mysql-5.5.62//bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/local/mysql-5.5.62//mysql-test ; perl mysql-test-run.pl

 以上到此已經安裝成功了 mysql 還須要一些設置才能夠正常運行

安裝配置

配置Mysql

chown -R mysql:mysql data

chown 777 /etc.my.cnf

cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld

chmod +x /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

chkconfig --list mysqld

mkdir /var/lib/mysql

chmod 777 /var/lib/mysql

 

開啓服務

service mysqld start

 

設置PATH

vi ~/.bash_profile

 在文件最後面加入如下內容,並使用:wq保存

export PATH=$PATH:/usr/local/mysql-5.5.62/bin

刷新PATH

source ~/.bash_profile

以上操做完成就既能夠正常使用 mysql 了, 爲了後期的方便使用, 咱們還要進行必定的優化設置已經安全性設置等

mysql 基本使用及設置

登陸mysql

這時mysql沒有密碼, 當出現Enter password:時直接回車

mysql -uroot -p

 

修改root密碼

mysql> use mysql
mysql> update user set password=password('須要設置的密碼') where user='root' and host='localhost';
mysql> flush privileges;

 

配置遠程登陸

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '剛纔設置的root密碼' WITH GRANT OPTION;

到此全部配置所有完畢. 可使用遠程工具進行登陸了
