Linux下php5.4启动脚本,linuxphp5.4脚本
废话不多说,直接上步骤
1、修改php-fpm.conf配置文件
修改/usr/local/php/etc/php-fpm.conf(当然这个跟你配置的php路径相关)配置文件
启动pid=run/php-fpm.pid
; Pid file ; Note: the default prefix is /usr/local/php/var ; Default Value: none pid = run/php-fpm.pid
启动error_log=log/php-fpm.log
; Error log file ; If it's set to "syslog", log is sent to syslogd instead of being written ; in a local file. ; Note: the default prefix is /usr/local/php/var ; Default Value: log/php-fpm.log error_log = log/php-fpm.log
2、创建/etc/init.d/php文件
root@aliyun:~# cat /etc/init.d/php #!/bin/bash #Author:iranw #E-mail:wang_wenguan#yeah.net #Website:http://www.phpno.com # pid file pid="/usr/local/php/var/run/php-fpm.pid" # php-fpm path&file phpfpm="/usr/local/php/sbin/php-fpm" param=$1 phpnum=`ps -ef | grep php-fpm | wc -l` if [ "$param" = "stop" ]; then if [ "$phpnum" = "1" ]; then echo "Php process does not exist." exit 1 fi kill `cat $pid` echo "Close php processes. OK" exit 1 fi if [ "$param" = "start" ]; then if [ "$phpnum" != "1" ]; then echo "Php process exist." exit 1 fi $phpfpm echo "Open php processes. OK" exit 1 fi if [ "$param" = "restart" ]; then if [ "$phpnum" = "1" ]; then echo "Php process does not exist. Stop Failed." else kill `cat $pid` for i in `ps -ef | grep php-fpm | grep -v grep | awk {'print $2'}` do kill -9 $i echo "Kill $i successed." done echo "Close php processes. OK" fi $phpfpm if [ "$phpnum" != "1" ]; then echo "Open php processes. OK" else echo "Open php processes. Failed." fi exit 1 fi
3、修改权限
#chmod +x /etc/init.d/php
4、执行结果
假设你保存的文件名是: smple.sh
那么就:
chmod 755 smple.sh这是为了给他赋予运行权限
然后直接运行即可.
sh smple.sh
或者
./smple.sh
或者
source smple.sh
取决于你使用的是哪个Linux发行版,通常在/etc/rc.d /etc/init.d等目录下

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
