本次实验用Nginx+Mysql+PHP的源码包来编译安装一个LNMP系统,实验之前先做一些准备工作.
前期准备工作:
- 下载对应的源码包"
可以将源码包统一放在一个文件路径下方便管理,这个选/usr/local/src,直接用wget命令下载源码包即可,
Mysql源码包地址:
http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
PHP源码包的下载地址:
http://cn2.php.net/distributions/php-5.6.30.tar.gz
Nginx源码包的下载地址:
http://nginx.org/download/nginx-1.12.1.tar.gz
2.安装环境及依赖关系:
这里先提供一些环境按键是需要的一下服务,比如:gcc,prec-devel等等,在编译./configure的时候配置不一样所需要依赖的包有可能也不一样,这里不一一列举了,提供一个解决依赖问题的思路.
在./configure配置好选项后检查时如果缺少了哪一个依赖包会有一个configure:error:please reinstall XXXX distribution 的语句,看到这个你就可以yum -yinstall XXXX或XXXX.devel,然后再重新./configure编译一次,遇到依赖问题在安装在编译直到成功就ok了
这个就是编译安装时遇上依赖问题的一种排错方法.
这里简单列举一些依赖文件,
Mysql:
perl-Module-Install.noarch
libaio*
PHP:
libcurl-devel
Nginx:
pcre-devel
下载好源码包和依赖关系之后就可以开始配置了.
1. Mysql安装配置
解压缩源码包:
tar -zxvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
移动目录并进入:
mv mysql-5.6.35-linux-glibc2.5-x86_64 /usr/local/mysql
cd /usr/local/mysql
创建数据目录及用户名:
mkdir /data/
useradd mysql
执行初始化脚本:
./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
copy配置文件并配置:
cp support-files/my-default.cnf /etc/my.cnf
--------------分割线--------------
在vim /etc/my.cnf配置如下:
[root@localhost mysql]# vim /etc/my.cnf
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
datadir =/data/mysql #添加这个数据存放路径
# port = .....
# server_id = .....
# socket = .....
socket = /tmp/mysql.sock #还有这个,其他暂时不用动
...省略...
完成以上操作就可以启动Mysql服务了:
/etc/init.d/mysqld start
检查服务是否启动:
[root@localhost mysql]# netstat -lntp
Active Internet connections (only servers)

tcp6 0 0 :::3306 :::* LISTEN 5939/mysqld
#看到服务已经启动了
加入开机启动:
chkconfig --add mysqld
chkconfig mysqld on
2. PHP安装及配置
编译之前在此提醒一下,准备工作中的依赖问题提醒,这里并没有全部列出所有的依赖包,授人鱼不如授人与渔,试验环境及要安装的选项不同请按需自行安装缺少的依赖包.
解压并进入目录:
tar -zxvf php-5.6.30.tar.gz
cd php-5.6.30
创建 php-fpm用户:
useradd -s /sbin/nologin php-fpm
./configure:这里的选项很多,报错缺那个包就装那个包就ok了.
./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --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 --with-pear --with-curl
执行编译安装:
make && make install
copy配置文件
cp php.ini-production /usr/local/php-fpm/etc/php.ini
创建vim /usr/local/php-fpm/etc/php-fpm.conf:
[root@localhost php-5.6.30]# vim /usr/local/php-fpm/etc/php-fpm.conf
[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock #监听ip和端口，端口默认为9000
listen.mode = 666 #用来定义php-fcgi.sock文件的权限
user = php-fpm
group = php-fpm
pm = dynamic #后面这些都是关于进程的信息
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
~
:wq
拷贝启动脚本并修改权限:
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
设置开机启动:
chkconfig --add php-fpm
chkconfig php-fpm on
检查配置服务:
/usr/local/php-fpm/sbin/php-fpm -t
启动服务:
service php-fpm start
检查是否启动:
[root@localhost conf]# ps aux | grep php
root 42351 0.0 0.2 123448 4736 ? Ss 15:39 0:00 php-fpm: master process (/usr/local/php-fpm/etc/php-fpm.conf)
php-fpm 42352 0.0 0.2 125532 4900 ? S 15:39 0:00 php-fpm: pool www
php-fpm 42353 0.0 0.3 125532 6476 ? S 15:39 0:00 php-fpm: pool www
php-fpm 42354 0.0 0.2 125532 4904 ? S 15:39 0:00 php-fpm: pool www
php-fpm 42355 0.0 0.2 125532 4904 ? S 15:39 0:00 php-fpm: pool www
php-fpm 42356 0.0 0.2 125532 4908 ? S 15:39 0:00 php-fpm: pool www
php-fpm 42357 0.0 0.2 125532 4908 ? S 15:39 0:00 php-fpm: pool www
...省略...
服务启动成功了.
3. Nginx安装配置
解压缩并进入目录:
tar -zxvf nginx-1.12.1.tar.gz
cd nginx-1.12.1/
执行configure 检查编译环境:参数方面根据自己的需求去配置,依赖问题还是缺哪个包就装哪个包
./configure --prefix=/usr/local/nginx
执行编译:
make && make install
创建启动脚本: 在vim /etc/init.d/nginx中创建
#!/bin/bash
# chkconfig: - 30 21 #这个和下面的选项好正确,否则会报service nginx does not support chkconfig的错误,
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start()
{
echo -n $"Starting $prog: "
mkdir -p /dev/shm/nginx_temp
daemon $NGINX_SBIN -c $NGINX_CONF
RETVAL=$?
echo
return $RETVAL
}
stop()
{
echo -n $"Stopping $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -TERM
rm -rf /dev/shm/nginx_temp
RETVAL=$?
echo
return $RETVAL
}
reload()
{
echo -n $"Reloading $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -HUP
RETVAL=$?
echo
return $RETVAL
}
restart()
{
stop
start
}
configtest()
{
$NGINX_SBIN -c $NGINX_CONF -t
return 0
}
case "$1" in
start)
start

;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo $"Usage: $0 {start|stop|reload|restart|configtest}"
RETVAL=1
esac
exit $RETVAL
修改权限:
chmod 755 /etc/init.d/nginx
加入服务列表并开机启动:
chkconfig --add nginx
chkconfig nginx on
修改nginx.conf文件:文件路径在/usr/local/nginx/conf下,备份原来conf文件并创建新的配置文件,格式如下;
user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;

fastcgi_pass unix:/tmp/php-fcgi.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
}
}
}
检查错误:
[root@localhost mysql]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
启动Nginx:
service nginx start
检查服务是否启动:
[root@localhost mysql]# netstat -lntp |grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 46168/nginx: master
到这里LNMP服务已经搭建好了,现在来检查一下nginx是否能解析php,只要在在nginx的/usr/local/nginx/html目录下创建一个php文件,然后通过浏览器访问就能看到效果了.
[root@localhost php-5.6.30]# vim /usr/local/nginx/html/test.php
<?php
phpinfo();
?>
~
:wq
如果php生效了会出现如下图片:
