##function of install lnmp

lnmp() {

check_service mysqld

check_service nginx

check_service phpfpm

echo "The lnmp done, Please use 'http://your ip/index.php' to access."

}

        echo "Only 'lamp' or 'lnmp' your can input."

第一个知识点

sed -i '/^\[mysqld\]$/a\datadir = /data/mysql' /etc/my.cnf （http://www.cnblogs.com/MYSQLZOUQI/p/5164877.html lanmp一键安装脚本）

第二个知识点

变量和字符串比较不能用-eq ，数字比较才能用-eq，要用==

if [ "$1"=="phpfpm" ]

上面mysql的安装无论5.1或5.6的shell代码都是一样的，只是下载的包不同

第三个知识点

#完全重定向

cat > /usr/local/apache2/htdocs/index.php <<EOF

<?php

phpinfo();

EOF

第四个知识点

shell的变量和函数命名不能有横杠

只能是大小写字母下划线数字

if [ "$1" == "phpfpm" ]

第五个知识点

平台可以用arch命令，获取是i686还是x86_64

[root@steven ~]# arch

x86_64

第六个知识点

curl http://www.apelearn.com/study_v2/.nginx_init -o /etc/init.d/nginx

curl 文件已存在会直接覆盖

-O大o下载文件，不需要指定名字： curl -O http://study.lishiming.net/index.html

-o小o下载文件，需要自定义名字： curl -o /tmp/index2.html http://study.lishiming.net/index.html

wget 文件已存在会直接覆盖

下载文件，不需要指定名字： wget http://www.minjieren.com/wordpress-3.1-zh_CN.zip

大写的O下载并以不同的文件名保存: wget -O wordpress.zip http://www.minjieren.com/download.aspx?id=1080

第七个知识点

#为了跟check_service保持一致，这里是phpfpm

[ -f /etc/init.d/phpfpm ] || /bin/cp sapi/fpm/init.d.php-fpm /etc/init.d/phpfpm

chmod 755 /etc/init.d/phpfpm
