lnmp shell安装脚本

LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构。LNMP是现在大多数大型公司在用的web环境,nginx小巧高效的web服务器和反向代理服务器，相对于apach占用资源更少，抗并发力更强，而且处理静态文件速度非常快。Mysql是一个小型关系型数据库管理系统。PHP是一种 HTML 内嵌式的语言，是一种在服务器端执行的嵌入HTML文档的脚本语言。这四种软件均为免费软件，组合到一起，成为一个免费、高效的网站服务系统。接近过年，笔者在家闲着没事写了个LNMP的Shell安装脚本，笔者现在还是个在学校学习的菜鸟，有可以优化的地方，希望大家能提出来，感谢。

接下来来解释下脚本代码

                    4) Install nginx and php
                    5) Install lnmp(linux nginx,mysql,php)

EOF
echo -n "Please you enter (1-5):"
read  enter

首先用eof将我们想要显示的界面给cat打印出来，然后用read读取一个输入的变量给enter这个变量。

#install pcre

#install nginx

then1=‘./configure --user=www --group=www --prefix=/usr/local/nginx‘
nginxinstall=‘make‘
nginxinstall2=‘make install‘
setnginx1=‘sed -i "s/\/scripts/$document_root/g" /usr/local/nginx/conf/nginx.conf‘
startnginx1=‘/usr/local/nginx/sbin/nginx‘

installnginx(){
$zlib
$downloadpcre
$tarpcre1
$cdpcredir
$install2
$install3
$install4
$cplibpcre
$addgroup

$addlogdir
$httpdstop
$dirmod
$downloadnginx
$sec
$then0
$then1
$nginxinstall
$nginxinstall2
$setnginx1
$startnginx1
}

我们将安装nginx的需要的pcre先编译安装了，定义好变量名，直接用$加变量名，使用这些命令就行了，然后再安装nginx。

installmysql()
{
rm -rf /etc/my.cnf
touch /etc/my.cnf
cat >> /etc/my.cnf << EOF
[mysqld]

character-set-server = utf8mb4
default_storage_engine = innodb
log_timestamps = SYSTEM
socket=/tmp/mysql.sock
basedir=/usr/local/mysql

max_connections = 1000
max_connect_errors = 1000
table_open_cache = 1024
max_allowed_packet = 128M
open_files_limit = 65535
explicit_defaults_for_timestamp=true

[mysqld_safe]

pid-file=/usr/local/mysql/data/fzjh.pid

[log]

EOF

    if [ $(uname -p) == x86_64 ]
        then
        wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
        tar -zvxf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
        mv  mysql-5.7.20-linux-glibc2.12-x86_64 /usr/local/mysql
        rm -rf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
    else
        wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.20-linux-glibc2.12-i686.tar.gz
        tar -zvxf mysql-5.7.20-linux-glibc2.12-i686.tar.gz
        mv  mysql-5.7.20-linux-glibc2.12-i686 /usr/local/mysql
        rm -rf mysql-5.7.20-linux-glibc2.12-i686.tar.gz
    fi

addmysqluser=‘useradd mysql -s /sbin/nologin‘
createdatadir=‘mkdir /usr/local/mysql/data‘
installmysql=‘/usr/local/mysql/bin/mysql_install_db  --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data‘
startmysql=‘/usr/local/mysql/support-files/mysql.server restart‘

$addmysqluser
$createdatadir
$installmysql
$startmysql

dbpasswd=$(cat /root/.mysql_secret | grep -v ‘#‘)
}

然后是mysql，首先删除掉系统内的my.cnf，用touch加EOF将我们自己的my.cnf创建好，然后使用uname -p 来检测我们的系统是多少位的，在下载相应的mysql安装包。

chajian(){
if [ $(rpm -qa | grep libxml2-devel | wc -l) != 0 ];then
echo libxml2 libxml2-devel is installed
else
yum install libxml2 libxml2-devel -y
fi
if [ $(rpm -qa | grep curl-devel | wc -l) != 0 ];then
 echo curl-devel is installed
else
yum install -y curl-devel
fi

if [ $(rpm -qa | grep wget | wc -l) != 0 ]
then
 if [ $(rpm -qa | grep gcc-c++ | wc -l) != 0 ];then
echo "wget and gcc gcc-c++ is installed"
else
yum install -y gcc gcc-c++
fi
else
yum install -y wget
fi

if [ $(rpm -qa | grep zlib-devel | wc -l) != 0 ];then
  echo  "zlib-devel is install"
else
  yum install -y zlib-devel

fi

PS:这些是用if语句检测一些要依赖的包

#installphp

downloadphp=‘wget http://au1.php.net/get/php-7.1.10.tar.gz/from/this/mirror -O php-7.1.10.tar.gz‘

set2=‘mv /usr/local/php/etc/php-fpm.d/www.conf.default  /usr/local/php/etc/php-fpm.d/www.conf‘
set3=‘mv php.ini-development /usr/local/php/bin/php.ini‘

installphp(){
$downloadphp
$tarphp
$gophpdir
if [ enter == 5 ]
    then
./configure --prefix=/usr/local/php --enable-fpm --with-curl --with-mysql=/usr/local/mysql --with-pdo-mysql
    else
./configure --prefix=/usr/local/php --enable-fpm --with-curl
fi
$maketest
$makeinstall
$set1
$set2
$set3
}

此为php的安装方法，和上面几个差不多一个样。笔者觉得入股安装lnmp必须使用pod-mysql来使mysql和php可以链接在一起。

case $enter in
1)
chajian

clear
echo ‘nginx file:/usr/local/nginx‘
echo ‘html file:/usr/local/nginx/html‘

echo ‘php file:/usr/local/php‘
echo ‘mysql file:=/usr/local/mysql‘
echo ‘you mysql_user:root‘
echo  you mysql_password:$dbpasswd
esac

最后使用case多选来通过enter变量输入的值来，根据case来进行相对应的安装。
最后感谢各位的阅读，希望各位有可以优化的地方提出来，互相学习。

python3自动安装脚本，python3.x与python2.x共存

1.前言: python3过程中,通过搜索一些文章参考安装过程发现比较麻烦,而且还出现一些不可预期的报错.python3环境需要升级openssl,所以为了部署到其他环境更方便,写自动安装脚本方式,且安装模式为python3.x与python2.x共存,防止可能发生原有环境异常的情况. 现在我把脚本分享出来,希望可以帮助到有需要的人,业务采集监控python脚本文件不提供,因为那些跟实际业务开发关联比较紧,比较没有参考意义也不方便公开. shell自动安装脚本,只需按说明简单修改配置,和调用集成
