Nginx 安装
系统平台：CentOS 8.2 64位， Nginx版本：nginx-1.21.3。
一、安装编译工具及库文件
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
二、首先要安装 PCRE
1、下载 PCRE 安装包，下载地址： downloads.sourceforge.net/project/pcr…
[root@VM-8-4-centos ~]# cd /usr/local/src/
[root@VM-8-4-centos ~]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.45/pcre-8.45.tar.gz
2、解压安装包
[root@VM-8-4-centos src]# tar zxvf pcre-8.345.tar.gz
3、进入安装包目录
[root@VM-8-4-centos src]# cd pcre-8.45/
4、编译安装
[root@VM-8-4-centos pcre-8.45]# ./configure
[root@VM-8-4-centos pcre-8.45]# make && make install
5、查看pcre版本
[root@VM-8-4-centos pcre-8.45]# pcre-config --version
三 、安装 Nginx
1、下载 Nginx，下载地址：nginx.org/download/ng…
[root@VM-8-4-centos src]# cd /usr/local/src/
[root@VM-8-4-centos src]# wget http://nginx.org/download/nginx-1.21.3.tar.gz
2、解压安装包
[root@VM-8-4-centos src]# tar zxvf nginx-1.21.3.tar.gz
3、进入安装包目录
[root@VM-8-4-centos src]# cd nginx-1.21.3
4、编译安装
[root@VM-8-4-centos nginx-1.21.3]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.45
[root@VM-8-4-centos nginx-1.21.3]# make && make install
5、查看nginx版本
[root@VM-8-4-centos nginx-1.21.3]# /usr/local/webserver/nginx/sbin/nginx -v
四、Nginx 配置
1、创建 Nginx 运行使用的用户 www：
[root@VM-8-4-centos conf]# /usr/sbin/groupadd www
[root@VM-8-4-centos conf]# /usr/sbin/useradd -g www www
2、备份nginx.conf
[root@VM-8-4-centos nginx-1.21.3]# cd /usr/local/webserver/nginx/conf/
[root@VM-8-4-centos conf]# cp nginx.conf nginx.conf.bak
3、配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
[root@VM-8-4-centos conf]# vi nginx.conf
user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
use epoll;
worker_connections 65535;
}
http
{
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
#charset gb2312;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
#limit_zone crawler $binary_remote_addr 10m;
#下面是server虚拟主机的配置
server
{
listen 80;#监听端口
server_name localhost;#域名
index index.html index.htm index.php;
root /usr/local/webserver/nginx/html;#站点目录
location ~ .*.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*.(gif|jpg|jpeg|png|bmp|swf|ico)$
{
expires 30d;
# access_log off;
}
location ~ .*.(js|css)?$
{
expires 15d;
# access_log off;
}
access_log off;
}
}
4、检查配置文件nginx.conf的正确性命令：
[root@VM-8-4-centos conf]# /usr/local/webserver/nginx/sbin/nginx -t
五、设置Nginx 开机自动启动
1、创建nginx.service文件
[root@VM-8-4-centos conf]vi /lib/systemd/system/nginx.service
[Unit]
Description=nginx service
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/webserver/nginx/sbin/nginx #启动命令
ExecReload=/usr/local/webserver/nginx/sbin/nginx -s reload #载入配置文件
ExecStop=/usr/local/webserver/nginx/sbin/nginx -s quit
PrivateTmp=true
[Install]
WantedBy=multi-user.target
2、设置开机自启动
[root@VM-8-4-centos src]# systemctl enable nginx
3、启动nginx服务
[root@VM-8-4-centos src]# systemctl start nginx.service
