修改linux环境变量

基于centos8进行测试

切换php版本

ls /usr/bin/php -al    //查看当前指向php版本路径
rm -rf /usr/bin/php    //删除当前软连接
ln -s /www/server/php/74/bin/php /usr/bin/php    //新建软连接

安装nginx并设置开机自启动

安装

yum install nignx  //安装
service nginx start  //启动nginx服务
systemctl enable nginx.service   //设置开机自启动
netstat -anp |grep :80   //查看80端口监听情况

安装目录/etc/nginx
php项目存放目录（var下新建www目录）
开放端口

//查看已开放的端口：
firewall-cmd --list-ports
//默认80端口加入防火墙访问白名单中：
firewall-cmd --permanent --zone=public --add-port=80/tcp
使用命令使其生效：
firewall-cmd --reload

常见问题

在www目录下新建项目，并新建index.php文件测试，访问端口，发现404并自动下载index.php文件：（编辑nginx.conf配置文件）

location / {
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index index.php; 
    fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name; 
    fastcgi_param PATH_INFO  $fastcgi_script_name;  
    include   fastcgi_params;
}

安装mysql5.7.31

下载并安装MySQL

[root@localhost ~]# wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

使用上面的命令就直接下载了安装用的Yum Repository，大概25KB的样子，然后就可以直接yum安装了。

[root@localhost ~]# yum -y install mysql57-community-release-el7-10.noarch.rpm

之后就开始安装MySQL服务器：

[root@localhost ~]# yum -y install mysql-community-server

注意：这步会耗费很长时间，最好手动去中科大网站下载
http://mirrors.ustc.edu.cn/mysql-ftp/Downloads/
下载完上传到/var/cache/dnf/mysql57-community-65b9ecb4cc6a2553/packages，这个文件夹可以使用find / -name mysql命令查看。上传完之后再次执行

yum -y install mysql-community-server

MySQL数据库设置

首先启动MySQL

[root@localhost ~]# systemctl start  mysqld.service

查看MySQL运行状态：

[root@localhost ~]# systemctl status mysqld.service

此时MySQL已经开始正常运行，不过要想进入MySQL还得先找出此时root用户的密码，通过如下命令可以在日志文件中找出密码：

[root@localhost ~]# grep "password" /var/log/mysqld.log

如下命令进入数据库：

[root@localhost ~]# mysql -uroot -p

输入初始密码，此时不能做任何事情，因为MySQL默认必须修改密码之后才能操作数据库：

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';

这里有个问题，新密码设置的时候如果设置的过于简单会报错，如果要允许设置简单密码需要修改mysql的配置。
更新mysql的语言
首先重新登录mysql，然后输入status：

cd /etc  //进入etc目录
vi my.conf  //打开my.conf文件,新增4行代码

[client] default-character-set=utf8

symbolic-links=0

保存更改后的my.cnf文件后，重启下mysql，然后输入status再次查看，你就会发现变化啦
service mysqld restart
最终安装目录/usr/bin/mysql

安装PHP7.3

下载

cd /usr/local/src
# wget -O 下载并重命名为
wget -O php-7.3..tar.gz http://php.net/get/php-7.3.2.tar.gz/from/a/mirror
# 解压
tar -xvzf php-7.3..tar.gz

配置

cd php-7.3.2
yum -y install libcurl-devel
yum -y install libXpm-devel
yum -y install libxml2-devel
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-pdo-mysql=/usr/bin/mysql --with-mysqli=/usr/bin/mysql_config --with-mysql-sock=/tmp/mysql.sock --with-pdo-mysql=/usr/bin/mysql --with-gd --with-png-dir=/usr/local/libpng --with-jpeg-dir=/usr/local/jpeg --with-freetype-dir=/usr/local/freetype --with-xpm-dir=/usr/ --with-zlib-dir=/usr/local/zlib --with-iconv --enable-libxml --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-opcache --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --enable-session --with-curl --enable-ctype

注意：—with-pdo-mysql=/usr/bin/mysql —with-mysqli=/usr/bin/mysql_config —with-mysql-sock=/tmp/mysql.sock —with-pdo-mysql=/usr/bin/mysql这几个目录要写对。
如果提示：configure: error: jpeglib.h not found

yum -y install libjpeg-turbo-devel.x86_64

如果提示：configure: error:png.h not found

yum install libpng-devel

如果提示：configure: error: freetype-config not found.

yum install freetype-devel

如果提示：Error: mysql_config not found

cd /usr/local
#下载mysql-community-devel
wget https://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql-community-devel-5.7.31-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.31-1.el7.x86_64.rpm

安装完发现/usr/bin下出现了mysql_config文件，继续执行./configure命令串
如果提示：configure: error: off_t undefined; check your library configuration

# 添加搜索路径到配置文件
echo '/usr/local/lib64
/usr/local/lib

/usr/lib64'>>/etc/ld.so.conf
# 更新配置
ldconfig -v

安装

make && make install
#删除临时文件
make clean
make distclean

配置PHP

到之前编译的源码包中将 php.ini-production 复制到 /usr/local/php/php.ini

cp php.ini-production /usr/local/php/php.ini

复制启动脚本

cp ./sapi/fpm/init.d.php-fpm.in /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm

修改php-fpm配置文件

cd /usr/local/php/etc
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf

去掉pid = run/php-fpm.pid前面的分号。:wq! 保存并退出。
修改/etc/init.d/php-fpm
将

php_fpm_BIN=@sbindir@/php-fpm php_fpm_CONF=@sysconfdir@/php-fpm.conf php_fpm_PID=@localstatedir@/run/php-fpm.pid

改成

php_fpm_BIN=/usr/local/php/sbin/php-fpm php_fpm_CONF=/usr/local/php/etc/php-fpm.conf php_fpm_PID=/usr/local/php/var/run/php-fpm.pid

执行

chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig php-fpm on

如果出现：
WARNING: Nothing matches the include pattern ‘/usr/local/php/etc/php-fpm.d/*.conf’ from /usr/local/php/etc/php-fpm.conf at line 143
执行：

# cd /usr/local/php/etc/php-fpm.d/
# cp www.conf.default www.conf
# /usr/local/php/sbin/php-fpm -t
[12-Oct-2017 08:33:29] NOTICE: configuration file /usr/local/php/etc/php-fpm.conf test is successful
[root@localhost php-fpm.d]# service php-fpm start
Starting php-fpm  done

建立软连接，将PHP添加到环境变量

ln -s /usr/local/php/bin/php /usr/sbin/php

安装Git

yum -y install git

yum安装git被安装在/usr/libexec/git-core目录

安装swoole

下载安装

1、wget https://github.com/swoole/swoole-src/archive/v4.4.16.tar.gz ## 下载
2、tar -zvxf v4.4.16.tar.gz  ## 解压到当前目录
3、cd swoole-src-4.4.16/ ## cd目录
4、phpize ## 使用phpize创建php编译检测脚本 ./configure
5、./configure --with-php-config=/usr/local/php/bin/php-config --enable-openssl  ## 创建编译文件,第一个--with,后面是php的安装路径/bin/php-config ,第二个--enable,是开启swoole的ssl功能
6、sudo make && make install  ## 编译swoole并把编译好的文件移动到php的扩展目录(前面的配置php版本的扩展目录) 需要root权限

这个时候已经安装成功,需要进入php.ini,在最后面增加上:

extension=swoole.so

成功安装swoole,通过php --ri swoole查看swoole扩展的信息:

swoole

Swoole => enabled Author => Swoole Team team@swoole.com Version => 4.4.16 Built => Jan 21 2021 15:22:51 coroutine => enabled epoll => enabled eventfd => enabled signalfd => enabled cpu_affinity => enabled spinlock => enabled rwlock => enabled openssl => OpenSSL 1.1.1g FIPS 21 Apr 2020 pcre => enabled zlib => 1.2.11 mutex_timedlock => enabled pthread_barrier => enabled futex => enabled async_redis => enabled

常见问题

phpize 命令不存在

yum install php-devel

Extension ‘swoole’ not present
解决：
将/usr/local/php中的php.ini文件复制到/usr/local/php/etc目录中

安装redis

安装

1.获取redis资源
　　wget http://download.redis.io/releases/redis-4.0.8.tar.gz
2.解压
　　tar xzvf redis-4.0.8.tar.gz
3.安装
　　cd redis-4.0.8
　　make
　　cd src
　　make install PREFIX=/usr/local/redis
4.移动配置文件到安装目录下
　　cd ../
　　mkdir /usr/local/redis/etc
　　mv redis.conf /usr/local/redis/etc
5.配置redis为后台启动
　　vi /usr/local/redis/etc/redis.conf //将daemonize no 改成daemonize yes
6.将redis加入到开机启动
　　vi /etc/rc.local //在里面添加内容：/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf (意思就是开机调用这段开启redis的命令)
7.开启redis
　　/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf 
8.将redis-cli,redis-server拷贝到bin下，让redis-cli指令可以在任意目录下直接使用
　　cp /usr/local/redis/bin/redis-server /usr/local/bin/
　　cp /usr/local/redis/bin/redis-cli /usr/local/bin/

设置redis密码

a.运行命令：redis-cli
b.查看现有的redis密码(可选操作，可以没有)
运行命令：config get requirepass 如果没有设置过密码的话运行结果会如下图所示
c.设置redis密码
运行命令：config set requirepass ****(为你要设置的密码)，设置成功的话会返回‘OK’字样
d.测试连接
重启redis服务
//（redis-cli -h 127.0.0.1 -p 6379 -a （为你设置的密码））
输入 redis-cli 进入命令模式，使用 auth ‘*‘ （**为你设置的密码）登录

修改linux环境变量

该方法是修改系统环境配置文件，需要管理员权限或者对该文件的写入权限：

# 如果/etc/bashrc文件不可编辑，需要修改为可编辑
chmod -v u+w /etc/environment
vim /etc/profile
# 在最后一行加上
export PATH=$PATH:/home/uusama/mysql/bin

注意事项：

生效时间：新开终端生效，或者手动source /etc/environment生效
生效期限：永久有效
生效范围：对所有用户有效
