make && make install
3.创建所需的用户
[root@bogon nginx-1.14.0]# useradd nginx -s /sbin/nologin -M
4.链接命令目录
[root@bogon nginx-1.14.0]#ln -s /usr/local/nginx1.14/sbin/nginx /usr/local/sbin/
5.开启nginx，查看端口
nginx
[root@bogon nginx-1.14.0]# netstat -anpt | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 5671/nginx: master
6.修改/usr/local/nginx1.14/conf/nginx.conf

7.修改/etc/security/limits.conf

8.查看现在是否没变

9.注销一下，重新查看一下，是否变化

10.开启nginx，查看nginx变化

11.页面访问一下nginx

二、部署 LNMP （部署环境需求：nginx和php在一台，再开启一台apache做防盗链）
1.安装php
首先安装libmcrypt 和依赖包

编译安装php
./configure --prefix=/usr/local/php5.6 --with-mysql=mysqlnd --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-openssl --enable-fpm --enable-sockets --enable-sysvshm --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --with-mhash --with-mcrypt=/usr/local/libmcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --enable-maintainer-zts

make && make intall

提供 php 配置文件
[root@bogon php-5.6.27]# cp php.ini-production /etc/php.ini

为 php-fpm 提供脚本

提供 php-fpm 配置文件并编辑

修改/usr/local/php5.6/etc/php-fpm.conf

启动php 查看9000端口
/etc/init.d/php-fpm start
[root@bogon etc]# netstat -anpt | grep 9000
tcp 0 0 0.0.0.0:9000 0.0.0.0:* LISTEN

修改/usr/local/nginx1.14/conf/nginx.conf

创建/usr/local/nginx1.14/html/index.php

测试

内核参数优化 添加 /etc//sysctl.conf

fs.file-max = 999999
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
net.ipv4.tcp_max_tw_buckets = 6000
net.ipv4.tcp_sack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_rmem = 10240 87380 12582912
net.ipv4.tcp_wmem = 10240 87380 12582912
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608

net.ipv4.tcp_max_syn_backlog = 262144
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 1
net.ipv4.tcp_syn_retries = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_fin_timeout = 1
net.ipv4.tcp_keepalive_time = 30
net.ipv4.ip_local_port_range = 1024 65000

执行 sysctl -p 使内核修改生效

查看更新值

修改/usr/local/nginx1.14/conf/nginx.conf

}
access_log off;
}
location / {
root html;
index index.php index.html index.htm;
}
location /status {

}
把之前php测试页注释掉

location ~ .*.(php|php5)?$ {

fastcgi_cache_use_stale error timeout invalid_header http_500;
fastcgi_cache_key http://$host$request_uri;
}

重启php
nginx -s reload

测试

三、验证、压力测试
查看ab的安装包
yum provides ab

安装httpd-tools
yum -y install httpd-tools

压力测试
ab -c 2000 -n 10000 192.168.1.50/index.html

ab -c 2000 -n 10000 192.168.1.50/index.php

两次压力测试做对比

验证防盗链
使用 apache 做为一个测试站点，域名为 www.test.com，在测试页上做一个超链接，链接 nginx

在apache主机上创建vim /var/www/html/index.html

开启httpd
systemctl start httpd

测试

论坛
Php服务器解压 压缩包
unzip Discuz_7.0.0_FULL_SC_UTF8.zip
cd Discuz_7.0.0_FULL_SC_UTF8/
ls
ls upload/

修改/etc/php.ini

Mysql服务器

进入MySQL
mysql -u root -p123

创建数据库
create database bbs;

grant all on . to root@‘192.168.1.%‘ identified by ‘123.com‘;
