1.Nginx的編譯安裝
#1.安裝Nginx所依賴的庫文件或開發包
yum install gcc redhat-rpm-config libxslt-devel gd-devel perl-ExtUtils-Embed geoip-devel gperftools-devel pcre-devel openssl-devel -y
#2.下載軟件、解壓
useradd nginx
wget http://nginx.org/download/nginx-1.14.2.tar.gz
tar xf nginx-1.14.2.tar.gz
cd nginx-1.14.2/
#3.編譯
./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_perl_module=dynamic --with-threads --with-stream --with-stream_ssl_module --with-http_slice_module --with-mail --with-mail_ssl_module --with-file-aio --with-http_v2_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic'
make
make install
#4.給Nginx1.14版本添加第三方模塊 nginx_upstream_check_module
wget https://github.com/yaoweibin/nginx_upstream_check_module/archive/master.zip
unzip master.zip
cd nginx-1.14.2/
#打個補丁
patch -p1 <../nginx_upstream_check_module-master/check_1.14.0+.patch
#編譯安裝
./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_perl_module=dynamic --with-threads --with-stream --with-stream_ssl_module --with-http_slice_module --with-mail --with-mail_ssl_module --with-file-aio --with-http_v2_module --add-module=/root/nginx_upstream_check_module-master --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic'
make
make install
2.驗證下該模塊是否可用
vim /etc/nginx/conf.d/upstream_check.conf
-----------/etc/nginx/conf.d/upstream_check.conf-------------
upstream blog.oldxu.com {
server 172.16.1.7:80;
server 172.16.1.8:80;
check interval=5000 rise=2 fall=3 timeout=1000 type=tcp;
#interval檢測間隔時間，單位為毫秒
#rsie表示請求2次正常，標記此后端的狀態為up
#fall表示請求3次失敗，標記此后端的狀態為down
#type 類型為tcp
#timeout為超時時間，單位為毫秒
}
upstream webserver {
server 172.16.1.7:80;
server 172.16.1.8:80;
check interval=5000 rise=2 fall=3 timeout=1000 type=tcp;
}
upstream php {
server 172.16.1.7:80;
server 172.16.1.8:80;
check interval=5000 rise=2 fall=3 timeout=1000 type=tcp;
}
server {
listen 8888;
location / {
proxy_pass http://blog.oldxu.com;
}
location /upstream_status {
check_status; #開啟upstream狀態頁面
}
}
----------/etc/nginx/conf.d/upstream_check.conf結束-----------
3.nginx平滑升級
#1.安裝Nginx所需依賴包
yum install gcc redhat-rpm-config
libxslt-devel gd-devel perl-ExtUtils-Embed
geoip-devel gperftools-devel pcre-devel openssl-devel -y
#2.下載并編譯Nginx
wget http://nginx.org/download/nginx-1.16.1.tar.gz
tar xf nginx-1.16.1.tar.gz
cd nginx-1.16.1/
rm -f /etc/nginx/conf.d/upstream_check.conf #由于該三方模塊不兼容1.16版本，所以拿掉避免升級出錯
./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_perl_module=dynamic --with-threads --with-stream --with-stream_ssl_module --with-http_slice_module --with-mail --with-mail_ssl_module --with-file-aio --with-http_v2_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic'
make #僅make即可，不需要make install，make后會生成新的二進制文件
#3.將舊的nginx二進制文件進行備份，然后替換成為新的nginx二進制文件
mv /usr/sbin/nginx /usr/sbin/nginx.old
cp objs/nginx /usr/sbin/nginx
#4.向舊的Nginx的Master進程發送USR2信號。（ 平滑升級二進制可執行文件 ）
[root@nfs nginx-1.16.1]# ps -ef |grep nginx
root 20848 1 0 10:21 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
nginx 20863 20848 0 10:22 ? 00:00:00 nginx: worker process
nginx 20864 20848 0 10:22 ? 00:00:00 nginx: worker process
#發送信號
[root@nfs nginx-1.16.1]# kill -USR2 20848
#pid文件會自動添加.oldbin后綴，該文件中記錄的是舊master的pid進程號
[root@nfs nginx-1.16.1]# cat /var/run/nginx.pid.oldbin
20848
#新老master共存了
[root@nfs nginx-1.16.1]# ps -ef |grep nginx
root 20848 1 0 10:21 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf （OLD）
nginx 20863 20848 0 10:22 ? 00:00:00 nginx: worker process
nginx 20864 20848 0 10:22 ? 00:00:00 nginx: worker process
root 24971 20848 0 11:37 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf （NEW）
nginx 24972 24971 0 11:37 ? 00:00:00 nginx: worker process
nginx 24973 24971 0 11:37 ? 00:00:00 nginx: worker process
#驗證站點是否正常
#5.向舊的master進程發送WINCH信號，舊的worker子進程優雅退出。
[root@nfs nginx-1.16.1]# kill -WINCH 20848
[root@nfs nginx-1.16.1]# ps -ef |grep nginx
root 20848 1 0 10:21 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
root 24971 20848 0 11:37 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
nginx 24972 24971 0 11:37 ? 00:00:00 nginx: worker process
nginx 24973 24971 0 11:37 ? 00:00:00 nginx: worker process
#6.向舊的master進程發送QUIT信號，舊的master進程就退出了。
[root@nfs nginx-1.16.1]# kill -QUIT 20848
[root@nfs nginx-1.16.1]# ps -ef |grep nginx
root 24971 1 0 11:37 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
nginx 24972 24971 0 11:37 ? 00:00:00 nginx: worker process
nginx 24973 24971 0 11:37 ? 00:00:00 nginx: worker process
