centos下编译安装lnmp

centos下编译安装lnmp

本文以centos为背景在其中编译安装nginx搭建lnmp环境。

编译安装nginx时，需要事先安装 开发包组"Development Tools"和"Server Platform Development"，同时还需专门安装pcre-devel包。

安装命令

        yum -y groupinstall "Development Tools"
        yum -y groupinstall "Development Tools"
        yum -y groupinstall "Server Platform Development"

创建nginx运行的用户和用户组

        groupadd -r nginx
        useradd -g nginx -r nginx

创建编译安装时需要的目录( --http-client-body-temp-path=)

        mkdir -pv /var/tmp/nginx/client

下载nginx源码 此处我下载的是nginx-1.4.7

        cd /usr/local/src
        wget http://mirrors.sohu.com/nginx/nginx-1.4.7.tar.gz
        tar xf nginx-1.4.7.tar.gz
        cd nginx-1.4.7
        ./configure \--prefix=/usr/local/nginx \--sbin-path=/usr/local/nginx/sbin/nginx \--conf-path=/etc/nginx/nginx.conf \--error-log-path=/var/log/nginx/error.log \--http-log-path=/var/log/nginx/access.log \--pid-path=/var/run/nginx/nginx.pid  \--lock-path=/var/lock/nginx.lock \--user=nginx \--group=nginx \ --with-http_ssl_module \--with-http_flv_module \--with-http_stub_status_module \--with-http_gzip_static_module \--http-client-body-temp-path=/var/tmp/nginx/client/ \--http-proxy-temp-path=/var/tmp/nginx/proxy/ \--http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \--http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \--http-scgi-temp-path=/var/tmp/nginx/scgi \--with-pcre
        make && make install

创建nginx SysVinit脚本

	#!/bin/sh
	#
	# nginx - this script starts and stops the nginx daemon
	#
	# chkconfig:   - 85 15
	# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \

	# Source networking configuration.
	. /etc/sysconfig/network  

	# Check that networking is up.
	[ "$NETWORKING" = "no" ] && exit 0   

	nginx="/usr/local/nginx/sbin/nginx"
	prog=$(basename $nginx)   

	NGINX_CONF_FILE="/etc/nginx/nginx.conf" 

	[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx  

	lockfile=/var/lock/subsys/nginx  

	make_dirs() {
	   # make required directories
	   user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
	   options=`$nginx -V 2>&1 | grep 'configure arguments:'`
	   for opt in $options; do
	       if [ `echo $opt | grep '.*-temp-path'` ]; then
	           value=`echo $opt | cut -d "=" -f 2`
	           if [ ! -d "$value" ]; then
	               # echo "creating" $value
	               mkdir -p $value && chown -R $user $value
	           fi
	       fi
	   done
	}   

	start() {
	    [ -x $nginx ] || exit 5
	    [ -f $NGINX_CONF_FILE ] || exit 6
	    make_dirs
	    echo -n $"Starting $prog: "
	    daemon $nginx -c $NGINX_CONF_FILE
	    retval=$?
	    echo
	    [ $retval -eq 0 ] && touch $lockfile
	    return $retval
	}   

	stop() {
	    echo -n $"Stopping $prog: "
	    killproc $prog -QUIT
	    retval=$?
	    echo
	    [ $retval -eq 0 ] && rm -f $lockfile
	    return $retval
	}   

	restart() {
	    configtest || return $?
	    stop
	    sleep 1
	    start
	}   

	reload() {
	    configtest || return $?
	    echo -n $"Reloading $prog: "
	    killproc $nginx -HUP
	    RETVAL=$?
	    echo
	}   

	force_reload() {
	    restart
	}   

	configtest() {
	  $nginx -t -c $NGINX_CONF_FILE
	}   

	rh_status() {
	    status $prog
	}   

	rh_status_q() {
	    rh_status >/dev/null 2>&1
	}   

	case "$1" in
	    start)
	        rh_status_q && exit 0
	        $1
	        ;;
	    stop)
	        rh_status_q || exit 0
	        $1
	        ;;

	        rh_status_q || exit 7
	        $1

	        force_reload
	        ;;

	        rh_status

	        rh_status_q || exit 0
	            ;;
	    *)
	        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
	        exit 2
	esac

为脚本添加可执行权限

chmod +x /etc/rc.d/init.d/nginx

添加nginx开机自启动

chkconfig --add nginx
chkconfig nginx on

编辑nginx配置文件

vi /etc/nginx/nginx.conf
location ~ \.php$ {
fastcgi_pass   10.170.2.90:9000;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  /var/www/html$fastcgi_script_name;
include        fastcgi_params;
}

在server内添加网站的根目录 /var/www/html

启动nginx

/etc/init.d/nginx start

测试是否启动成功

	curl 127.0.0.1

应该看到 welcome to nginx

此时nginx告一段落

安装php切换到源码目录

	cd /usr/local/src
	wget http://am1.php.net/distributions/php-5.6.28.tar.bz2
	tar xf php-5.6.28.tar.bz2
	cd php-5.6.28
	./configure --prefix=/usr/local/php5 --with-mysql=mysqlnd --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-openssl --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --enable-fpm --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2

如果有错误提示根据相应的提示安装

我这里提示了2个问题

• xml2-config not found. Please check your libxml2 installation.
  
  按如下命令安装 yum install libxml2-devel -y

• mcrypt.h not found. Please reinstall libmcrypt
  
  按照如下方法解决 源码安装libmcrypt

            cd /usr/local/src
    wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/attic/libmcrypt/libmcrypt-2.5.7.tar.gz
    tar -zxvf libmcrypt-2.5.7.tar.gz
    cd libmcrypt-2.5.7
    ./configure --prefix=/usr/local
    make
    make install
  

继续切换到php源码目录

	cd /usr/local/src/php-5.6.28
	make
	make install

有可能在make过程中出现

make: *** [ext/fileinfo/libmagic/apprentice.lo] Error 1

看网上文章解释 这是由于机器内存过小造成的 解决办法

在./configure加上选项:--disable-fileinfo

所以完整的命令为

	cd /usr/local/src/php-5.6.28
	./configure --prefix=/usr/local/php5 --with-mysql=mysqlnd --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-openssl --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --enable-fpm --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --disable-fileinfo

拷贝php.ini

cp php.ini-production /etc/php.ini

配置php-fpm

 cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm
 chmod +x /etc/rc.d/init.d/php-fpm
 chkconfig --add php-fpm
 chkconfig php-fpm on
 cp /usr/local/php5/etc/php-fpm.conf.default /usr/local/php5/etc/php-fpm.conf

编辑 /usr/local/php5/etc/php-fpm.conf

vi /usr/local/php5/etc/php-fpm.conf

修改以下值

	pm.max_children = 50
	pm.start_servers = 5
	pm.min_spare_servers = 2
	pm.max_spare_servers = 8
	pid = /usr/local/php5/var/run/php-fpm.pid

测试是否安装成功 写入php文件

	vi /var/www/html/index.php

输入如下

	<?php
	phpinfo();
	?>

启动php-fpm

	/etc/init.d/php-fpm start
	curl 127.0.0.1

此时应该得到回应

安装mysql

	yum install -y mysql-server mysql mysql-deve

初始化

	service mysqld start

设置root密码

	/usr/bin/mysqladmin -u root password '123456'

重新启动mysql

	service mysqld restart

此时root密码为123456php应该可以连接了
