centos6.8下安装部署LNMP（备注：nginx1.8.0+php5.6.10+mysql5.6.12）

在平时运维工作中，经常需要用到LNMP应用框架。
以下对LNMP环境部署记录下：

1）前期准备：为了安装顺利，建议先使用yum安装依赖库
[root@opd ~]#yum install -y make cmake gcc gcc-c++ autoconf automake libpng-devel libjpeg-devel zlib libxml2-devel ncurses-devel bison libtool-ltdl-devel libiconv libmcrypt mhash mcrypt libmcrypt-devel pcre-devel openssl-devel freetype-devel libcurl-devel

2）安装nginx
[root@opd ~]#cd /opt/src
[root@src ~]#wget http://nginx.org/download/nginx-1.8.0.tar.gz
[root@src ~]#tar -zxvf nginx-1.8.0.tar.gz
[root@src ~]#cd nginx-1.8.0
添加www用户，其中-M参数表示不添加用户家目录，-s参数表示指定shell类型
[root@nginx-1.8.0 ~]#useradd www -M -s /sbin/nologin
[root@nginx-1.8.0 ~]#vim auto/cc/gcc
将这句注释掉取消Debug编译模式 大概在179行
#CFLAGS="$CFLAGS -g"

我们再配置下nginx编译参数
[root@nginx-1.8.0 ~]#./configure --prefix=/opt/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module
[root@nginx-1.8.0 ~]#make
[root@nginx-1.8.0 ~]#make install clean
添加开机自启动
[root@nginx-1.8.0 ~]#vim /etc/rc.local
在这个文件里面添加：/opt/nginx/sbin/nginx
[root@nginx-1.8.0 ~]#/opt/nginx/sbin/nginx

----------------------------------顺便说下：Centos7采用yum方式安装nginx-----------------------------------
centos7系统库中默认是没有nginx的rpm包的，所以我们自己需要先更新下rpm依赖库
1）使用yum安装nginx需要包括Nginx的库，安装Nginx的库
# rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2）使用下面命令安装nginx
# yum install nginx

3）启动Nginx
# service nginx start
或
# systemctl start nginx.service
---------------------------------------------------------------------------------------------------------

3）安装PHP
由于PHP需要这些类库的支撑
先下载PHP
[root@opd ~]#cd /opt/src/
[root@src ~]#wget http://cn2.php.net/distributions/php-5.6.10.tar.gz
[root@src ~]#tar -zxvf php-5.6.10.tar.gz
[root@src ~]#cd php-5.6.10
我们先配置下PHP的编译参数
[root@php-5.6.10 ~]#./configure --prefix=/opt/php --with-mysql --with-mysqli --with-iconv-dir --with-zlib --with-libxml-dir --enable-xml --with-curl --enable-fpm --enable-mbstring --with-gd --with-openssl --with-mhash --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-libdir=/usr/lib64 --with-jpeg-dir=/usr/lib64 --with-freetype-dir=/usr/lib64 --with-png-dir=/usr/lib64
[root@php-5.6.10 ~]#make
[root@php-5.6.10 ~]#make install clean
复制php.ini
[root@php-5.6.10 ~]#cp php.ini-development /opt/php/lib/php.ini
[root@php-5.6.10 ~]#cd /opt/php/etc/
[root@php-5.6.10 ~]#cp php-fpm.conf.default php-fpm.conf        //在php-fpm.conf文件中可以定义php的服务端口、进程启动的用户和组权限（最好和nginx服务启动权限一直）等。
使用PHP-FPM管理脚本，在编译包里面已经配置好了，只需要复制到/etc/init.d/中即可
[root@php-5.6.10 ~]#cd /opt/src/php-5.6.10/sapi/fpm/
[root@php-5.6.10 ~]#cp init.d.php-fpm /etc/init.d/php-fpm
[root@php-5.6.10 ~]#chmod +x /etc/init.d/php-fpm
启动php-fpm
[root@php-5.6.10 ~]#service php-fpm start   or   /etc/init.d/php-fpm restart
加入开机启动策略
[root@php-5.6.10 ~]#chkconfig --add php-fpm
[root@php-5.6.10 ~]#chkconfig php-fpm on
