PHP 5.5 Redis Memcache Supervisor Beanstalk
MySQL 5.6（略，裝在Windows7 host機上 ）
開機自動啟動eth0網路
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
ONBOOT=yes
6.9 yum預設安裝的php是5.3.3版本
因為CentOS通常提供7-10年的生命週期，所以這很難讓php（和其他packages）維持在最新的版本，你能這麼做：
1. 裝5.3.3版
2. 使用源碼(source)去編譯安裝(build)
3. 使用有提供可選擇的三方源( 3rd party repository )
我選擇#3
使用webtatic.com源
https://webtatic.com/packages/php55/
Webtatic has now ended support for PHP 5.5
Webtatic 已終止PHP 5.5的支持
使用remirepo源
https://blog.remirepo.net/post/2016/09/10/PHP-5.5-is-dead
安裝remirepo源
# wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
# rpm -Uvh remi-release-6*.rpm
warning: remi-release-6.rpm: Header V4 DSA/SHA1 Signature, key ID 00f97f56: NOKEY

1:remi-release ########################################### [100%]
查remirepo源版本
# yum info remi-release
...
Name : remi-release
Version : 6.9
如果你要最新的php 5.5.x，必須這樣做
# yum --enablerepo=remi,remi-php55 update -y
安裝PHP 5.5
# yum install php55-php
因為安裝的是remi源的php 5.5，所以命令行直接輸入php會找不到指令，要輸入php55
解法
# source /opt/remi/php55/enable
安裝php-fpm（yum預設的php-fpm是5.3.3的，所以要照下面這樣裝）
# yum install php55-php-fpm
安裝nginx
# yum install nginx
安裝memcached
# yum install memcached
安裝redis
# yum install redis
安裝supervisor
# yum install supervisor
啟動supervisor
# supervisord -c /etc/supervisord.conf
只有supervisor比較特殊，如果用service supervisor start的話，只會執行php artisan queue:listen tube-name 但不會生成 php artisan queue:work tube-name
安裝beanstalk
# yum install beanstalkd
配置nignx
/etc/nginx/conf.d/default.conf
server {
...
location / {
index index.php index.html index.htm;
}
...
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
s啟動php-fpm、nginx、memcached、redis、beanstalkd
# service php55-php-fpm start
# service nginx start
# service memcached start
# service redis start
# service beanstalkd start
開啟80 port
# iptables -I INPUT 5 -i eth0 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT
# service iptables save
如不開啟 Windows chrome訪問 VM會報錯 ERR_CONNECTION_TIMED_OUT
telnet 會不通，但是在VM上 curl http://localhost 能訪問
配置後，記得換瀏覽器試試，不然chrome配置前訪問過，配置後仍然會卡住
看iptables有哪些規則
# iptables -S
# iptables --line -vnL
開機自動啟動php-fpm、nginx、memcached、redis、beanstalkd
# chkconfig nginx on
# chkconfig php55-php-fpm on
# chkconfig memcached on
# chkconfig redis on
# chkconfig beanstalkd on
檢查
# chkconfig --list nginx
nginx 0:off 1:off 2:on 3:on 4:on 5:on 6:off
0~6是linux的runlevel
Virtualbox降版本
原本使用最新版Virtualbox 5.2.8
因為重裝一台Virtualbox也會遇到開機卡在creating process for virtual machine (gui/qt) ... (1/2) 的問題
https://www.youtube.com/watch?v=20p-r5WzYXg
這邊說要降版本到4.3.10
降到4.3.10後打開虛擬機會有連不上網路的問題
# ifup eth0
Determining IP information for eth0... failed; no link present. Check cable?
解法
Virtualbox選你的虛擬機 => 設置 => 網路 => 選你的網卡 => 高級 => 勾選"接入網線"
Virtualbox選你的虛擬機 => 設置 =>聲音 => 取消勾選"啟用聲音"
安裝php所需擴展
# yum install php55-php-mcrypt
# yum install php55-php-pdo
# yum install php55-php-pecl-memcached
# yum install php55-php-gd //防止圖片驗證碼報錯：Call to undefined function Johntaa\Captcha\imagecreatefrompng()
# yum install php55-php-pecl-xdebug
# service php55-php-fpm restart
laravel 連不上redis
網頁報錯 Permission denied [tcp://127.0.0.1:6379]
但是 telnet 127.0.0.1 6379 和 redis-cli 可以通
因為
# getsebool httpd_can_network_connect
httpd_can_network_connect --> off
解法
# /usr/sbin/setsebool httpd_can_network_connect=1
Use -P option makes the change permanent. Without this option, the boolean would be reset to 0 at reboot.
使用-P選項使其永久更改，否則重開機設定會被重置
解法2
把它寫到 /etc/rc.d/rc.local 下 => 解決
laravel虛擬域名千萬不能配置有底線（_） 否則會被轉跳到
http://x_web.centos/http://x_web.centos/auth/signin
讓php能在command line使用
因為用remi裝的php55，所以命令行輸入php會找不到，只能用php55
解法：
# source /opt/remi/php55/enable
因為supervisor執行時吃不到這句，所以command路徑要寫完全
command = /opt/remi/php55/root/usr/bin/php /path/artisan queue:listen ga2-xxx
查remi裝的php.ini在哪
# php -i | grep "Loaded Configuration File"
Loaded Configuration File => /opt/remi/php55/root/etc/php.ini
解決 could not find driver 錯誤
# php -m | grep pdo
pdo_sqlite // 只有這個，沒有pdo_mysql所以出錯
安裝php55-php-mysqlnd（其實我安裝的是php55-php-pecl-mysqlnd-qc，但是會一起裝php55-php-mysqlnd）
# yum install php55-php-pecl-mysqlnd-qc
為什麼會裝php55-php-pecl-mysqlnd-qc？
因為
# yum search pdo_mysql
...
php55-php-pecl-mysqlnd-qc.x86_64 : A query cache plugin for mysqlnd
