一直想用NGINX替換現有的APACHE,最近終於開始做了。

負載均衡+7臺NGINX伺服器作為後端。挺爽的，呵呵。開始做吧 。。。

一，安裝NGINX

# yum install -y pcre pcre-devel
# yum install -y zlib zlib-devel
# yum install -y openssl openssl-devel

# mkdir nginx-src && cd nginx-src
# wget http://nginx.org/download/nginx-1.7.3.tar.gz
# tar xzf nginx-1.7.3.tar.gz 
# cd nginx-1.7.3
 

./configure \
--prefix=/usr/local/nginx \
--with-http_realip_module \
--with-http_sub_module \
--with-http_gzip_static_module \
--with-http_stub_status_module  \
--with-pcre

#make install

#ln-sf /usr/local/nginx/sbin/nginx/usr/sbin

#nginx -t //成功了

修改nginx配置檔案

“>” 這個符號之前阿銘介紹過，為重定向的意思，單獨用它，可以把一個文字文件快速清空。

安裝PHP  和 php-fpm

請檢視http://heilinux.blog.51cto.com/6123663/1575582

其中的配置：

 ./configure \
--prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--enable-fpm \
--with-fpm-user=php-fpm \
--with-fpm-group=php-fpm \
--with-mysql=mysqlnd \
--with-mysql-sock=/tmp/mysql.sock \
--with-libxml-dir \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-iconv-dir \
--with-zlib-dir \
--with-mcrypt \
--enable-soap \
--enable-gd-native-ttf \
--enable-ftp \
--enable-mbstring \
--enable-exif \
--disable-ipv6 \
--with-pear \
--with-curl \
--with-openssl

配置php.ini以及php-fpm,並新增為啟動項

cp php.ini-production /usr/local/php/etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default.conf  php-fpm.conf

儲存配置檔案後，檢驗配置是否正確的方法為:

/usr/local/php/sbin/php-fpm -t

如果出現諸如 “test is successful” 字樣，說明配置沒有問題。

啟動php-fpm

vim /etc/init.d/php-fpm

輸入一下內容：

[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
user = nobody
group = nobody
listen.owner = nobody
listen.group = nobody
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

設定

chmod 755 /etc/init.d/php-fpm
service php-fpm start

如果想讓它開機啟動，執行:

chkconfig php-fpm on

檢測是否啟動:

ps aux |grep php-fpm

netstat -ant |grep 9000

新增 PHP 命令到環境變數

編輯 ~/.bash_profile，將：

PATH=$PATH:$HOME/bin
改為：
PATH=$PATH:$HOME/bin:/usr/local/php56/bin

使 PHP 環境變數生效：

# . ~/.bash_profile

thinkphp關鍵的配置是在nginx的配置中的路由設定。
