CentOS6.x/CentOS7.x一鍵安裝mysql5.

一、系統環境及說明

????系統：CentOS6.x_x64? mysql:社區版5.6.21,開源數據庫用的最多的mysql，編譯安裝比較繁瑣，yum安裝版本比較低且默認安裝的位置是/var/下，本次采用官方下載的rpm包，通過腳本自動化安裝并定制數據目錄到獨立分區中(本次為/data1目錄)

另外補充部分是給出針對Ubuntu/CentOS7的實際配置;最后提供了腳本一鍵安裝;注意的是glibc版本要大于2.12

二、準備安裝包

1、官方下載

#https://dev.mysql.com/downloads/mysql/5.6.html#downloads?選擇對應的版本和平臺軟件包：

MySQL-shared-compat-5.6.x-1.el6.x86_64.rpm???? #x就是你下的版本號以下類同
MySQL-devel-5.6.x-1.el6.x86_64.rpm
MySQL-shared-5.6.x-1.el6.x86_64.rpm
MySQL-client-5.6.x-1.el6.x86_64.rpm
MySQL-test-5.6.x-1.el6.x86_64.rpm
MySQL-server-5.6.x-1.el6.x86_64.rpm

2、本實驗用到的包

http://pan.baidu.com/s/1nvn0nUx包含了以下軟件包(也是從官方下載)：

MySQL-shared-compat-5.6.21-1.el6.x86_64.rpm
MySQL-devel-5.6.21-1.el6.x86_64.rpm
MySQL-shared-5.6.21-1.el6.x86_64.rpm
MySQL-client-5.6.21-1.el6.x86_64.rpm
MySQL-test-5.6.21-1.el6.x86_64.rpm
MySQL-server-5.6.21-1.el6.x86_64.rpm

三、安裝mysql5.6

1、如果是官方下載的請直接執行下面操作

#rpm?-ivh?MySQL-shared-compat-5.6.x-1.el6.x86_64.rpm???????#提供基礎依賴組件，需要第一個安裝?
#yum?remove?mysql-libs?-y??????????????#御載默認自帶的mysql-lib
#yum?install?libaio?-y?????????????????????????#安裝libiao
#rpm?-ivh?MySQL-devel-5.6.x-1.el6.x86_64.rpm
#rpm?-ivh?MySQL-shared-5.6.x-1.el6.x86_64.rpm
#rpm?-ivh?MySQL-client-5.6.x-1.el6.x86_64.rpm
#rpm?-ivh?MySQL-test-5.6.x-1.el6.x86_64.rpm
#rpm?-ivh?MySQL-server-5.6.x-1.el6.x86_64.rpm

說明:以上直接安裝的數據目錄在/var/lib/mysql下?但有時你并不希望?數據目錄和/目錄在一個分區(磁盤)上
因此可通過腳本重重新初始化安裝到別的目錄;完成自定制;

2、本實驗腳本如下：

將以上rpm包放到一個目錄,創建my.cnf文件(公供參考)

cat my.cnf

[mysqld]

#?GENERAL?#

default-storage-engine?????????=?InnoDB

注意:生產環境有些優化參數請按需修改;以上僅供參考;您也可以到https://tools.percona.com/ ? 網站填寫相關參數生成配置文件;

并在目錄中創建一個install.sh腳本內容如下:

cat install.sh

#!/bin/bash
src_dir=$(pwd)
cd?$src_dir
rpm?-ivh?MySQL-shared-compat-5.6.21-1.el6.x86_64.rpm
yum?remove?mysql-libs?-y
yum?install?libaio?-y
rpm?-ivh?MySQL-devel-5.6.21-1.el6.x86_64.rpm
rpm?-ivh?MySQL-shared-5.6.21-1.el6.x86_64.rpm
rpm?-ivh?MySQL-client-5.6.21-1.el6.x86_64.rpm
rpm?-ivh?MySQL-test-5.6.21-1.el6.x86_64.rpm
rpm?-ivh?MySQL-server-5.6.21-1.el6.x86_64.rpm

#service?mysql?start?&&?echo?"mysql5.6.21?has?installes?sucess!"
#mysql_root_pwd=`gawk?-F?:?'{?print?$4?}'?/root/.mysql_secret`
#echo?"A?random?root?password?has?been?set.?You?will?find?it?in?'/root/.mysql_secret'."
#echo?"The?random?root?password?was:'${mysql_root_pwd//?}'"

service?mysql?stop
[?-d?/data1/mysqldb/data?]?||?mkdir?-p?/data1/mysqldb/data
[?-d?/data1/mysqldb/log?]?||?mkdir?-p?/data1/mysqldb/log
chown?mysql.mysql?/data1/mysqldb?-R
cd?$src_dir
cp?${src_dir}/my.cnf?/etc
cd?/usr/bin
./mysql_install_db?--user=mysql?--basedir=/usr?--datadir=/data1/mysqldb/data???#遷移數據目錄到/data1/mysqldb/data下可自行定制
cd?/var/lib
mv?mysql?/tmp
mkdir?mysql
chown?mysql.mysql?mysql

service?mysql?start?&&?echo?"Mysql?root?password?was?empty.Please?change?when?you?login?mysql."
ln?-s?/data1/mysqldb/data/mysql.sock???/var/lib/mysql/mysql.sock???????#由于一些mysql工具默認到這里找mysql.sock所以做個軟鏈

??四、注意問題

1、關閉selinux否則腳本安裝不成功

2、安裝后系統自帶的postfix和crontab工具被御了，重新yum安裝 一次即可

3、mysql服務的root密碼為空，請自行修改root密碼

或在腳本中添加以下行 在mysql遷移好目錄啟動后自動修改mysql root密碼

mysqladmin -u root password "123.com"??????

補充部分:

CentOS7.x安裝 mysql 5.7.21

到mysql官方下載Linux通用包wget https://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz

解壓：

#yum?install?libaio1?numactl?-y
#tar?-xvf?mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz??-C?/usr/local
#ln?-sv?mysql-5.7.21-linux-glibc2.12-x86_64??mysql

添加環境變量

cat?/etc/profile.d/mysql.sh
export?PATH=/usr/local/mysql/bin:$PATH

初始化:

#useradd?-r?mysql
#mkdir?-pv?/data/mysql
#chown?mysql.mysql?/data/mysql?
#mysqld?--initialize-insecure??--datadir=/data/mysql?--user=mysql?--basedir=/usr/local/mysql/
#mkdir?/usr/local/mysql/etc/my.cnf.d
#chown?mysql.mysql?-R?/usr/local/mysql/etc
#cp?/etc/my.cnf?/usr/local/mysql/etc/
#cat?/usr/local/mysql/etc/my.cnf

[mysqld]
datadir=/data/mysql
socket=/tmp/mysql.sock
[mysqld_safe]
log-error=/usr/local/mysql/log/error.log
pid-file=/var/run/mysql/mysql.pid
!includedir?/usr/local/mysql/etc/my.cnf.d

??????????????????????
復制啟動腳本：

#cp?/usr/local/mysql/suppor-files/mysql.server?/etc/init.d/mysqld
#touch?/usr/local/mysql/log/error.log???
#chwon?mysql.mysql?/usr/local/mysql/log/error.log
#chmod?755?/usr/local/mysql/log/error.log
#chkconfig?--add?mysqld
#chkconfig?mysqld?on
#service?mysqld?start

Ubuntu 16.04上安裝

下載同樣的包

安裝的步驟與上面CentOS7類似，不同的是ubuntu 16.04上不支持service 方式管理

因此需要復制

#apt-get?install?libaio1?numactl??##?安裝依賴包
#cp?/usr/local/mysql/suppor-files/mysql.server?/etc/init.d/mysqld
#sudo?systemctl?daemon-reload
#chown?root.mysql?/usr/local/mysql?-R
#chmod?775?/usr/local/mysql?-R

#systemctl?enable?mysqld
#systemctl?start?mysqld
#systemctl?status?mysqld

如圖:

mysql -uroot -p

如圖：

注意安裝后mysql root密碼為空;請自行設置 root密碼;以下腳本一鍵安裝亦是如此！

一鍵安裝腳本

以上在CentOS7上安裝和Ubuntu 16.04下安裝大同小異,均可以安裝成功;因此整理成一鍵安裝腳本!

補充：

python pip install MySQL-python 時報錯

mysql_config 找不到問題

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

以及error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

ubuntu 執行如下命令

sudo apt-get install python-dev? \

build-essential libssl-dev libffi-dev \

libxml2-dev libxslt1-dev zlib1g-dev \
