由于公司要求需要最新版的ZABBIX2.4.4需要最新版的系统CENTOS7和新版的LNMP环境,所以本人摸索着使用新版的环境搭建了LNMP系统,环境版本如下:

  • 系统:CentOS 7 x86_64
  • NGINX:nginx-1.7.12
  • 数据库:mariadb-10.0.13
  • PHP:php-5.5.23

首先做一些准备工作,先把centos7的防火墙更换成iptables,可以参见如下链接

centos7防火墙设置iptables

修改成iptables之后就可以清空iptables里面的过滤规则了,然后再关闭selinux服务。记得不要忘了先安装gcc gcc-c++ wget net-tools等功能哦。

首先安装mariadb

应为数据库编译需要很长时间,所以我这里下载的是已经编译好了的二进制包,下载版本为 mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz 

1、下载二进制包到/usr/local/src 目录下:

复制代码 代码如下:[root@centos74 ~]# cd /usr/local/src/
[root@centos74 src]# wget http://ftp.osuosl.org/pub/mariadb/mariadb-10.0.13/bintar-quantal-amd64/mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz[/code]

2、将压缩包解压到/usr/local 目录下:

[code][root@centos74 src]# tar zvxf mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz -C /usr/local/

3、创建mariadb 数据初始化目录/data/mysql:

复制代码 代码如下:[root@centos74 src]# mkdir -p /data/mysql

4、添加系统用户mysql,禁止登陆系统,同时,将mariadb 数据初始化目录所属主和组都修改为mysql:
复制代码 代码如下:[root@centos74 src]# useradd -r -s /sbin/nologin mysql ;chown -R mysql.mysql /data/mysql/

5、重命名解压出来的mariadb 目录:

复制代码 代码如下:[root@centos74 src]# mv /usr/local/mariadb-10.0.13-linux-x86_64/ /usr/local/mysql

6、进入重命名后的目录,初始化mariadb:

[root@centos74 src]# cd /usr/local/mysql/
[root@centos74 mysql]# ./scripts/mysql_install_db --datadir=/data/mysql --user=mysql
Installing MariaDB/MySQL system tables in '/data/mysql' ...
140906 2:03:19 [Note] InnoDB: Using mutexes to ref count buffer pool pages
140906 2:03:19 [Note] InnoDB: The InnoDB memory heap is disabled

报错:WARNING: The host 'test4' could not be looked up with resolveip.
解决办法:vim /etc/hosts 在最后一行添加192.168.1.242 test4

报错:./bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解决办法:yum -y install libaio-devel libaio

7、复制配置文件到/etc目录覆盖之前的my.cnf:

复制代码 代码如下:[root@centos74 mysql]# cp support-files/my-large.cnf /etc/my.cnf
cp:是否覆盖"/etc/my.cnf"? y

8、复制mysql 启动脚本文件到/etc/init.d 目录下并重命名为mysqld:
复制代码 代码如下:[root@centos74 mysql]# cp support-files/mysql.server /etc/init.d/mysqld

同时修改启动脚本的权限为755:

复制代码 代码如下:[root@centos74 mysql]# chmod 755 !$
chmod 755 /etc/init.d/mysqld

9、编辑启动脚本,定义datadir 路径:

复制代码 代码如下:[root@centos74 mysql]# vim /etc/init.d/mysqld

定义数据存放路径:
datadir=/data/mysql

10、将mariadb自带命令放入$PATH

[root@localhost ~]# PATH=$PATH:/etc/init.d/#当前有效,重启shell就失效
[root@localhost ~]# echo "export PATH=$PATH:/etc/init.d/" /etc/profile
[root@localhost ~]# echo "export PATH=$PATH:/usr/local/mysql/bin/" /etc/profile
[root@localhost ~]# source !$

11、启动mariadb:

[root@centos74 mysql]# /etc/init.d/mysqld start

Starting MySQL. SUCCESS!

第二步,开始安装php

这里要先声明一下,针对Nginx的php安装和针对apache的php安装是有区别的,因为Nginx中的php是以fastcgi的方式结合nginx的,可以理解为nginx代理了php的fastcgi,而apache是把php作为自己的模块来调用的。同样的,php官方下载地址: http://www.php.net/downloads.php

下载php

[rot@localhost src]# cd /usr/local/src
[root@localhost src]# wget http://am1.php.net/distributions/php-5.5.23.tar.gz

解压php

[root@localhost src]# tar zxf php-5.5.23.tar.gz

创建相关账户

[root@localhost src]# useradd -s /sbin/nologin php-fpm

配置编译参数

复制代码 代码如下:[root@localhost src]# cd php-5.5.23
[root@localhost src]# yum -y install gcc make gd-devel libjpeg-devel libpng-devel libxml2-devel bzip2-devel libcurl-devel
[root@localhost php-5.5.23]# ./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-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --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 --enable-bcmath --enable-mbstring --enable-sockets --with-gd --with-libxml-dir=/usr/local --with-gettext

错误:configure: error: xml2-config not found. Please check your libxml2 installation.
解决办法:yum -y install libxml2-devel

错误:configure: error: Please reinstall the libcurl distribution -easy.h should be in <curl-dir>/include/curl/
解决办法:yum -y install libcurl-devel

错误:configure: error: jpeglib.h not found.
解决办法:yum -y install libjpeg-turbo-devel

错误:configure: error: png.h not found.
解决办法:yum -y install libpng-devel

错误:configure: error: freetype-config not found.
解决办法:configure: error: mcrypt.h not found. Please reinstall libmcrypt.

错误:configure: error: mcrypt.h not found. Please reinstall libmcrypt.
解决办法:yum -y install libmcrypt-devel

安装php

[root@localhost php-5.3.27]# make && make install

以上每一个步骤,如果没有完全执行正确,那么下一步是无法进行的,使用 echo $"htmlcode">

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

把如下内容写入该文件:

[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 = php-fpm
group = php-fpm
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

保存配置文件后,检验配置是否正确的方法为:

/usr/local/php/sbin/php-fpm -t

如果出现诸如 “test is successful” 字样,说明配置没有问题。

启动php-fpm

cp /usr/local/src/php-5.5.23/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
service php-fpm start


如果想让它开机启动,执行:

chkconfig php-fpm on

检测是否启动:

ps aux |grep php-fpm

看看是不是有很多个进程(大概20多个)。

安装nginx

下载nginx

cd /usr/local/src/
wget http://nginx.org/download/nginx-1.7.12.tar.gz

解压nginx

tar zxvf nginx-1.7.12.tar.gz

配置编译参数

cd nginx-1.7.12
./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

报错:./configure: error: the HTTP rewrite module requires the PCRE library.
解决办法:yum -y install pcre-devel

报错:./configure: error: the HTTP gzip module requires the zlib library.
解决办法:yum install -y zlib-devel

编译nginx

make

安装nginx

make install

编写nginx启动脚本,并加入系统服务

vim /etc/init.d/nginx

写入如下内容:

#!/bin/bash
# chkconfig: - 30 21
# 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 $NGINX_CONF
    RETVAL=$"Stopping $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -TERM
    rm -rf /dev/shm/nginx_temp
    RETVAL=$"Reloading $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -HUP
    RETVAL=$"$1" in
 start)
    start
    ;;
 stop)
    stop
    ;;
 reload)
    reload
    ;;
 restart)
    restart
    ;;
 configtest)
    configtest
    ;;
 *)
    echo $"Usage: $0 {start|stop|reload|restart|configtest}"
    RETVAL=1
esac

exit $RETVAL

保存后,更改权限:

chmod 755 /etc/init.d/nginx
chkconfig --add nginx

如果想开机启动,请执行:

chkconfig nginx on

更改nginx配置

首先把原来的配置文件清空:

> /usr/local/nginx/conf/nginx.conf

“>” 这个符号为重定向的意思,单独用它,可以把一个文本文档快速清空。

vim /usr/local/nginx/conf/nginx.conf

写入如下内容:

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;

events
{
  use epoll;
  worker_connections 6000;
}

http
{
  include mime.types;
  default_type application/octet-stream;
  server_names_hash_bucket_size 3526;
  server_names_hash_max_size 4096;
  log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'
  '$host "$request_uri" $status'
  '"$http_referer" "$http_user_agent"';
  sendfile on;
  tcp_nopush on;
  keepalive_timeout 30;
  client_header_timeout 3m;
  client_body_timeout 3m;
  send_timeout 3m;
  connection_pool_size 256;
  client_header_buffer_size 1k;
  large_client_header_buffers 8 4k;
  request_pool_size 4k;
  output_buffers 4 32k;
  postpone_output 1460;
  client_max_body_size 10m;
  client_body_buffer_size 256k;
  client_body_temp_path /usr/local/nginx/client_body_temp;
  proxy_temp_path /usr/local/nginx/proxy_temp;
  fastcgi_temp_path /usr/local/nginx/fastcgi_temp;
  fastcgi_intercept_errors on;
  tcp_nodelay on;
  gzip on;
  gzip_min_length 1k;
  gzip_buffers 4 8k;
  gzip_comp_level 5;
  gzip_http_version 1.1;
  gzip_types text/plain application/x-javascript text/css text/htm application/xml;

server
{
  listen 80;
  server_name localhost;
  index index.html index.htm index.php;
  root /usr/local/nginx/html;

  location ~ \.php$ {
    include fastcgi_params;
    fastcgi_pass unix:/tmp/php-fcgi.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
  }

}

}

保存配置后,先检验一下配置文件是否有错误存在:

/usr/local/nginx/sbin/nginx -t

如果显示内容如下,则配置正确,否则需要根据错误提示修改配置文件:

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

如果不能启动,请查看 “/usr/local/nginx/logs/error.log” 文件,检查nginx是否启动:

ps aux |grep nginx

看是否有进程。

测试是否解析php文件

创建测试文件:

vim /usr/local/nginx/html/2.php

内容如下:

<"htmlcode">
[root@localhost nginx]# curl localhost/2.php

或者使用浏览器打开http://YourServerIPAddress/2.php

重要:如果解析不了,检查日志发现连接不到php,我的php版本为5.5.23,比较新的版本,需要在php/etc/php-fpm.conf文件中添加

listen.owner = nobody
listen.group = nobody

这两行,再重启一下服务就能使用php了

原因是/tmp/php-fcgi.sock这个文件没有读权限

至此,最新版的LNMP环境源码编译安装完成了

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
