LNMP+Discuz论坛

LNMP指的是一个基于CentOS/Debian编写的Nginx、PHP、MySQL、phpMyAdmin、eAccelerator一键安装包。可以在独立主机上轻松的安装LNMP生产环境。

继上篇博客介绍的LAMP的Discuz论坛，本章博客为大家介绍基于LNMP的Discuz论坛的搭建。使用的软件基本上都是最新或者使用比较广泛的，毕竟学最新的知识，挨最毒的打，才会有成长。

环境介绍

系统	IP地址	内存	cpu
Centos 7	192.168.70.133	5G	4核

nginx版本1.8.1

php版本7.31 mysql版本5.7.21 密码：ruh5Discuz论坛版本3.3 密码：2olg

一、安装nginx

1、安装环境包

[root@localhost opt]# yum -y install gcc gcc-c++ gd-devel autoconf automake zlib zlib-devel openssl openssl-devel pcre*

2、解压软件包编译

[root@localhost opt]# tar zxf nginx-1.8.1.tar.gz

[root@localhost opt]# cd nginx-1.8.1/

./configure \

--prefix=/usr/local/nginx \

--user=nginx \

--group=nginx \

--with-http_ssl_module \

--with-http_gzip_static_module \

--with-http_image_filter_module \

--with-http_stub_status_module

编译注解--prefix=指向安装目录--user= 指定程序运行时的非特权用户--group= 指定程序运行时的非特权用户组--with-http_ssl_module 支持https请求，需已安装openssl--with-http_gzip_static_module  在线实时压缩输出数据流--with-http_image_filter_module 传输JPEG/GIF/PNG 图片的一个过滤器,默认为不启用。gd库要用到--with-http_stub_status_module  获取nginx自上次启动以来的工作状态

3、安装

[root@localhost nginx-1.8.1]# make && make install

4、优化命令路径

[root@localhost nginx-1.8.1]# ln -s /usr/local/nginx/sbin/nginx /usr/sbin/

5、创建nginx用户，添加一下简单的优化

[root@localhost nginx-1.8.1]# cd /usr/local/nginx/conf/

[root@localhost conf]# useradd -M -s /sbin/nologin nginx

[root@localhost conf]# vim nginx.conf

#以下是我的设置的一些简单的优化，删除了部分注释语句    user  nginx;    worker_processes  4;    worker_rlimit_nofile 65535;    events {            worker_connections  2048;            use epoll;    }

http {        include       mime.types;        default_type  application/octet-stream;        server_tokens off;sendfile   on;tcp_nopush on;tcp_nodelay on;server_names_hash_bucket_size 128;server_names_hash_max_size 512;keepalive_timeout  65;client_header_timeout 15s;client_body_timeout 15s;send_timeout 60s;gzip  on;gzip_buffers  4 64k;gzip_http_version 1.1;gzip_comp_level 2;gzip_min_length 1k;gzip_vary on;gzip_types text/plain text/javascript application/x-javascript text/css text/xml application/xml applicatin/xml+rss;server {    listen       80;    server_name  localhost;   location / {        root   html;        index  index.html index.htm;    }    error_page   500 502 503 504  /50x.html;    location = /50x.html {        root   html;    }    #location ~ \.php$ {    #    root           html;    #    fastcgi_pass   127.0.0.1:9000;    #    fastcgi_index  index.php;    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;    #    include        fastcgi_params;    #}}

}

6、查看语法并启动nginx

[root@localhost conf]# 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

[root@localhost conf]# nginx #启动nginx

7、关闭防火墙和selinux，网页中访问

[root@localhost conf]# systemctl stop firewalld.service

[root@localhost conf]# setenforce 0

网页中直接输入IP地址访问

二、安装mysql

本文依旧使用解压版的mysql5.7.21,文章开头已经为大家提供解压版的下载地址，使用解压版大幅度减少我们使用的时间。

1、解压安装包并更名

[root@localhost opt]# tar zxf mysql-5.7.21-linux-glibc2.12-x86_64.tgz

[root@localhost opt]# mv mysql-5.7.21-linux-glibc2.12-x86_64 mysql

2、修改配置文件

root@localhost opt]# vim /etc/my.cnf #删除原本的内容，添加如下

[client]port = 3306socket = /tmp/mysql.sock[mysqld]character-set-server = utf8mb4skip_name_resolve = 1user = mysqlport = 3306socket = /tmp/mysql.sockbasedir = /opt/mysql/datadir = /opt/mysql/datalog-error = /opt/mysql/data/log-error.logpid-file = /opt/mysql/data/mysql.pidinnodb_data_home_dir = /opt/mysql/dataslow-query-log-file=/opt/mysql/data/slow.logrelay-log-index = /opt/mysql/data/relaylogrelay-log-info-file = /opt/mysql/data/relaylogrelay-log = /opt/mysql/data/relaylogopen_files_limit = 10240table_open_cache = 2048back_log = 300max_connections = 10000max_connect_errors = 20explicit_defaults_for_timestamp = 1max_allowed_packet = 64Mthread_cache_size = 300query_cache_size = 256Mquery_cache_limit = 2Mquery_cache_min_res_unit = 2kdefault-storage-engine = InnoDBthread_stack = 512Ktransaction_isolation = READ-COMMITTEDtmp_table_size = 256Mmax_heap_table_size = 256Mkey_buffer_size = 2Gsort_buffer_size = 2Mjoin_buffer_size = 6Mread_buffer_size = 4Mread_rnd_buffer_size = 16Mbulk_insert_buffer_size = 64Mmyisam_sort_buffer_size = 128Mmyisam_max_sort_file_size = 15Gmyisam_repair_threads = 1interactive_timeout = 1800wait_timeout = 28800innodb_data_file_path = ibdata1:200M;ibdata2:200M;ibdata3:200M:autoextendinnodb_buffer_pool_size = 2Ginnodb_thread_concurrency = 0innodb_flush_log_at_trx_commit = 2innodb_log_buffer_size = 16Minnodb_log_file_size = 512Minnodb_log_files_in_group = 3innodb_max_dirty_pages_pct = 90innodb_lock_wait_timeout = 120innodb_purge_threads = 0slow_query_log = 1long_query_time = 3replicate-ignore-db = mysqlreplicate-ignore-db = testreplicate-ignore-db = information_schema#slave-skip-errors = 1032,1062,1026,1114,1146,1048,1396server-id = 1sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION[mysqldump]quickmax_allowed_packet = 64M

3、创建mysql用户并初始化数据库

[root@localhost opt]# adduser -s /sbin/nologin mysql

[root@localhost opt]# /opt/mysql/bin/mysqld --initialize-insecure

4、启动数据库，设置数据库密码

[root@localhost opt]# /opt/mysql/bin/mysqld_safe &

[root@localhost opt]# /opt/mysql/bin/mysqladmin -uroot password '123123'

5、进入数据库查看

[root@localhost opt]# /opt/mysql/bin/mysql -uroot -p123123

三、安装PHP7

1、安装依赖环境包

yum -y install pcre pcre-devel openssl openssl-devel libicu-devel gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel openldap-servers openldap-client nss_ldap jemalloc-devel cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel bzip2 bzip2-devel libxml2 libxml2-devel bzip2 bzip2-devel curl-devel gmp-devel readline-devel

2、解压安装包

[root@localhost opt]# tar zxf php-7.3.1.tar.gz

3、编译

[root@localhost opt]# cd php-7.3.1/

./configure \

--prefix=/usr/local/php7 \

--with-pdo-mysql=/opt/mysql \

--enable-mysqlnd \

--with-pdo-mysql=mysqlnd \

-with-mysqli=mysqlnd \

--with-mysql-sock=/tmp/mysql.sock \

--with-config-file-path=/usr/local/php7 \

--enable-fpm \

--enable-inline-optimization \

--disable-debug \

--disable-rpath \

--enable-shared \

--enable-soap \

--with-libxml-dir \

--with-xmlrpc \

--with-openssl \

--with-mhash \

--with-pcre-regex \

--with-sqlite3 \

--with-zlib \

--enable-bcmath \

--with-iconv \

--with-bz2 \

--enable-calendar \

--with-curl \

--with-cdb \

--enable-dom \

--enable-exif \

--enable-fileinfo \

--enable-filter \

--with-pcre-dir \

--enable-ftp \

--with-gd \

--with-openssl-dir \

--with-jpeg-dir \

--with-png-dir \

--with-zlib-dir \

--with-freetype-dir \

--enable-gd-jis-conv \

--with-gettext \

--with-gmp \

--with-mhash \

--enable-json \

--enable-mbstring \

--enable-mbregex \

--enable-mbregex-backtrack \

--with-onig \

--enable-pdo \

--with-zlib-dir \

--with-pdo-sqlite \

--with-readline \

--enable-session \

--enable-shmop \

--enable-simplexml \

--enable-sockets \

--enable-sysvmsg \

--enable-sysvsem \

--enable-sysvshm \

--enable-wddx \

--with-libxml-dir \

--with-xsl \

--enable-zip \

--with-pear \

--enable-opcache

编译会遇到几个小问题

●configure: error: Please reinstall the libzip distributiontar -zxvf libzip-1.2.0.tar.gzcd libzip-1.2.0./configuremake && make install

●configure: error: off_t undefined; check your library configuration

解决方法echo '/usr/local/lib64/usr/local/lib/usr/lib/usr/lib64'>>/etc/ld.so.conf&&ldconfig -v

●/usr/local/include/zip.h:59:21: 致命错误：zipconf.h：没有那个文件或目录

cp /usr/local/lib/libzip/include/zipconf.h /usr/local/include/zipconf.h++++系统不同缺包也不同，总而言之，缺什么装什么~

4、安装

[root@localhost php-7.3.1]# make && make install

5、复制php配置文件到指定目录，并优化命令路径

[root@localhost php-7.3.1]# cp php.ini-development /usr/local/php7/php.ini

[root@localhost opt]# cd /usr/local/php7/etc/

[root@localhost etc]# cp php-fpm.conf.default php-fpm.conf

[root@localhost php-7.3.1]# ln -s /usr/local/php7/bin/ /usr/local/bin/

[root@localhost php-7.3.1]# ln -s /usr/local/php7/sbin/ /usr/local/sbin/

6、创建php用户

useradd -M -s /sbin/nologin php

7、修改conf文件

[root@localhost php-7.3.1]# cd /usr/local/php7/etc/php-fpm.d

[root@localhost php-fpm.d]# cp www.conf.default www.conf

[root@localhost php-fpm.d]# vim www.conf

#修改以下几个参数

user = php #用户php

group = php #组php

pm.max_children = 50 # php-fpm 能启动的子进程的最大数量

pm.start_servers = 20 #动态方式下的起始php-fpm进程数量

pm.min_spare_servers = 5 #动态方式空闲状态下的最小php-fpm进程数量

pm.max_spare_servers = 35 #动态方式空闲状态下的最大php-fpm进程数量。

8、启动php-fpm

[root@localhost etc]# /usr/local/php7/sbin/php-fpm

9、查看php进程

[root@localhost etc]# pgrep php

17859

17860

17861

17862

17863

17864

17865

17866

17867

.........

查看端口：9000

[root@localhost etc]# netstat -ntap | grep 9000

tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 17859/php-fpm: mast

10、php连接nginx

[root@localhost etc]# cd /usr/local/nginx/conf/

[root@localhost conf]# vim nginx.conf

#添加index.php，识别默认首页   location / {                root   html;                index  index.html index.htm index.php;        }#去掉如下注释，这里需要将/scripts改成$document_root，否则nginx返回空白页面    location ~ \.php$ {        root           html;        fastcgi_pass   127.0.0.1:9000;        fastcgi_index  index.php;        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;        include        fastcgi_params;    }

11、修改默认首页

[root@localhost conf]# cd ../html/[root@localhost html]# vim index.php<?phpphpinfo();?>

12、重启nginx,网页中访问

[root@localhost html]# nginx -s reload网页中输入192.168.70.133/index.php需要有如下mysql扩展模块

13、php连接mysql

◆进数据库创建库并授权

/opt/mysql/bin/mysql -uroot -p123123

mysql> create database bbs;

mysql> grant all privileges on bbs.* to 'root'@'192.168.70.%' identified by '123123' with grant option;

mysql> flush privileges;

◆再次修改index.php文件

    PHP-link-MYSQL  Success!!";else echo "PHP-link-MYSQL Fail!!";?>

◆刷新刚刚的页面，显示PHP-link-MYSQL Success!!即可以连接数据库

四、安装Discuz论坛

1、修改nginx.conf文件，设置我们指定的安装目录[root@localhost html]# cd /usr/local/nginx/conf/[root@localhost conf]# vim nginx.conf

#这里将root后面原本的html换成/var/www        location  ~ \.(gif|jepg|png|bmp|ico)$ {            root   /var/www;            index  index.html index.htm index.php;            expires 1d;        }#将$document_root换成/var/www/        location ~ \.php$ {            fastcgi_pass   127.0.0.1:9000;            fastcgi_index  index.php;            fastcgi_param  SCRIPT_FILENAME   /var/www/$fastcgi_script_name;            include        fastcgi_params;        }

2、创建指定的目录

[root@localhost conf]# mkdir /var/www

3、解压Discuz项目包，将upload移动到/var/www下

[root@localhost opt]# unzip Discuz_X3.3_SC_UTF8.zip

[root@localhost opt]# mv upload/ /var/www/

4、授权，放大目录权限

[root@localhost opt]# cd /var/www/upload/

[root@localhost upload]# chown -R php config data uc_client/data uc_server/data/

[root@localhost upload]# chmod -R 777 ../upload

5、重启nginx,网页中访问安装

[root@localhost upload]# nginx -s reload网页中访问192.168.70.133/upload/install

[root@localhost upload]# vim /var/www/upload/source/class/class_core.php

再次刷新页面就好了，不然admin用户无法登陆哦
