--背景雲端
以前都喜歡了源碼安裝MySQL，總覺得源碼是高大上的事情，不過源碼也需要時間，特別是make的時候，如果磁盤和cpu差的話，時間很長很長，在虛擬機上安裝mysql尤其甚慢了。
現在業務發展了，開始在雲上部署了，需要經常安裝mysql，有的時候一次部署很多台，如果還是源碼安裝一個個去執行，效率就比較差了，所以准備采用更快效率的二進制來實現一鍵式自動化安裝mysql。
1，mysql二進制安裝包下載地址
下載地址：http://download.csdn.net/detail/mchdba/9488918，包括
1） 一鍵式自動安裝腳本：auto_install_mysql5.7.sh;
2） Mysql參數文件my.cnf
3） Mysql5.7二進制安裝包，在readme_mysql5.7_down_address.txt文件里面有下載地址連接，比mysql官網下載速度快很多倍。
PS：下載之后，將腳本已經所有軟件放在同一個目錄比如/soft目錄下面。

2，自動化初始化linux服務器腳本
執行bash -x init_linux.sh就開始自動初始化linux服務器了， 自動化安裝腳本init_linux.sh如下，下載地址為http://download.csdn.net/detail/mchdba/9488929：
| #1 instal jdk , add tomcat user sh init_jdk.sh
useradd tomcat mkdir -p /usr/local/app/ chown -R tomcat.tomcat /usr/local/app
#2 # vim /etc/sudoers echo "tomcat ALL=(ALL) ALL" >> /etc/sudoers

3，自動化安裝腳本
執行腳本bash -x auto_install_mysql5.7.sh，開始一鍵式安裝，自動化安裝腳本如下：
| # install the basie lib yum install cmake -y groupadd mysql useradd -g mysql mysql autoreconf --force --install libtoolize --automake --force automake --force --add-missing yum install -y libtoolize yum install gcc gcc-c++ -y yum install -y ncurses-devel.x86_64 yum install -y cmake.x86_64 yum install -y libaio.x86_64 yum install -y bison.x86_64 yum install -y gcc-c++.x86_64 yum install make -y
# add mysql account,create the basic directory mkdir -p /data/mysql/data cd /data/mysql/data chown -R mysql.mysql /data chown -R mysql.mysql /usr/local/mysql5711 mkdir -p /data/mysql/binlog/ chown -R mysql.mysql /data/mysql/binlog/ cd /usr/local/mysql5711/
# init databases rm -rf /data/mysql/data/* cp my.cnf /usr/local/mysql5711/my.cnf time bin/mysqld --defaults-file=/usr/local/mysql5711/my.cnf --initialize --user=mysql
# set the auto start on linux server started cp support-files/mysql.server /etc/init.d/mysql chmod 700 /etc/init.d/mysql echo "export PATH=$PATH:/usr/local/mysql5711/bin">>/etc/profile source /etc/profile chkconfig --add mysql
# do a soft link to start mysql cd /usr/local/ ln -s /usr/local/mysql5711 mysql
# remove default my.cnf mv /etc/my.cnf /tmp/
# set the default password /usr/local/mysql/bin/mysqld_safe --skip-grant-tables --skip-networking & /usr/local/mysql/bin/mysql -uroot --password='' --socket='/usr/local/mysql/mysql.sock' -e " update mysql.user set authentication_string=password('dns_yuerld') where user='root' and Host = 'localhost'; flush privileges;" /usr/local/mysql/bin/mysql -uroot --password='dns_yuerld' --socket='/usr/local/mysql/mysql.sock' -e " set PASSWORD=PASSWORD('dns_yuerld'); create database t; create table t1 select 1 as a; select * from t1;"
# restart the mysql server service mysql restart
# check the test /usr/local/mysql/bin/mysql -uroot --password='dns_yuerld' --socket='/usr/local/mysql/mysql.sock' -e " select * from t1;" |
4，批量安裝很多mysql實例
5，why？采用二進制安裝而不采用源碼安裝
主要是源碼安裝在make環節需要消耗太多時間，一次源碼安裝mysql需要很久，而二進制安裝免去了configure、make、make install這一步驟，大大縮減了安裝時間提升了效率，單台安裝mysql感覺不大，如果一次性安裝成千上萬台，這個差距就是天上地下咯。
另外：安裝過程中要實時查看控制台信息，如果有詭異的錯誤信息，要及時排查。
