lnmp shell安装脚本

Posted 2020-10-24

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。

#!/bin/bash

接下来来解释下脚本代码

clear

                    3) Install mysql
                    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。

installnginx(){

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

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

        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-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

    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。

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。
