linux下nginx编译安装、版本信息修改

环境

　　centos 7

安装依赖包

yum install -y  gcc gcc-c++ glibc glibc-devel pcre pcre-devel zlib zlib-devel openssl openssl-devel \
unzip psmisc bash-completion  libxml2 libxml2-devel libxslt libxslt-devel perl perl-ExtUtils-Embed

下载源码包

mkdir /usr/local/src
cd /usr/local/src

wget  http://nginx.org/download/nginx-1.20.1.tar.gz

tar -xf nginx-1.20.1.tar.gz


下载nginx_upstream_check_module模块

yum install -y git

cd /usr/local/src/

git clone https://github.com/yaoweibin/nginx_upstream_check_module.git

定制版本信息

　　版本号、服务器类型、错误页显示

cd /usr/local/src/nginx-1.20.1

修改版本

　　(本例修改为myweb)

　src/core/nginx.h 文件

　　第13行#define NGINX_VERSION

　　第14行#define NGINX_VER "nginx/" NGINX_VERSION

sed -i '/define NGINX_VERSION/s/1.20.1/123/' src/core/nginx.h

sed -i '/^#define NGINX_VER.*NGINX_VERSION$/s/nginx/myweb/' src/core/nginx.h

修改HTTP 响应头

　src/http/ngx_http_header_filter_module.c 文件

　　第49行 static u_char ngx_http_server_string[] = "Server: nginx" CRLF;

sed -i '/static u_char ngx_http_server_string/s/nginx/myweb/' src/http/ngx_http_header_filter_module.c

修改错误页底部提示

　src/http/ngx_http_special_response.c 文件

　　第36行 static u_char ngx_http_error_tail[] =

"<hr><center>nginx</center>" CRLF

sed -i '36s#nginx#myweb#' src/http/ngx_http_special_response.c

最终效果

添加nginx用户

useradd -r nginx -s /sbin/nologin

编译安装

./configure --prefix=/usr/local/nginx \
--user=nginx --group=nginx \
--pid-path=/usr/local/nginx/nginx.pid \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_stub_status_module \
--with-http_gzip_static_module \
--with-http_gunzip_module \
--with-http_v2_module \
--with-pcre \
--with-threads \
--with-file-aio \--with-stream \
--with-stream_ssl_module \
--with-stream_realip_module \
--add-module=/usr/local/src/nginx_upstream_check_module

make -j 4

make install

服务及开机自启

　　开机启动

系统服务(systemctl)

　　使用systemctl管理：systemctl start | stop | reload | enable | disable nginx

/usr/lib/systemd/system/nginx.service 文件

[Unit]
Description=The nginx HTTP and reverse proxy server
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/nginx.pid
# Nginx will fail to start if /run/nginx.pid already exists but has the wrong
# SELinux context. This might happen when running `nginx -t` from the cmdline.
# https://bugzilla.redhat.com/show_bug.cgi?id=1268621
ExecStartPre=/usr/bin/rm -f /run/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
KillSignal=SIGQUIT
TimeoutStopSec=5
KillMode=process
PrivateTmp=true

[Install]
WantedBy=multi-user.target

使用rc.local自启

　　不便或不需写为服务脚本放置于/etc/rc.d/init.d/目录，且又想开机时自动运行的命令，可直接放置于/etc/rc.d/rc.local文件中

cat >>/etc/rc.d/rc.local<<EOF

/usr/local/nginx/sbin/nginx

EOF

　　添加执行权限

chmod 755 /etc/rc.d/rc.local

环境变量

　　使用二进制nginx管理，不用每次都写一长串的绝对路径 nginx [-s reload | stop ]

方法1：PATH变量

cat >>/etc/profile.d/nginx.sh <<EOF
export PATH=/usr/local/nginx/sbin:$PATH
EOF

soure /etc/profile.d/nginx.sh

方法2：软链接

ln -s /usr/local/nginx/sbin/nginx /usr/bin

不显示版本号

主配置文件中添加

server_tokens off;
