Nginx - Upgrade
Upgrade test a .Nginx
Source Package Installation (Configuration 2. 3. Installation compiler)
1. First unzip the upgrade package [root @ vlnx251101 ~] # tar XF nginx-1.13.4.tar.gz 2. Go to the upgrade package that directory [root @ vlnx251101 ~] # cd nginx-1.13.4 / 3. specify a directory and other issues (prce-8.40) supports regular [root @ vlnx251101 nginx-1.13.4] # ./configure --prefix = / usr / local / nginx --user = nginx --group = nginx --with-http_ssl_module - File-http_stub_status_module --with-with-AIO---with-http_dav_module --with PCRE = .. / PCRE-8.40 [@ vlnx251101 Nginx the root-1.13.4] the make # 4. View the current version [root @ vlnx251101 nginx- 1.13.4] # / usr / local / nginx / sbin / nginx -v nginx Version: nginx / 1.12.1
5. The old backup of the previous [root @ mysqlb nginx-1.13.4] # mv / usr / local / nginx / sbin / nginx /usr/local/nginx/sbin/nginx.bak [root @ mysqlb nginx-1.13 .4] # LS Auto CHANGES.ru the configure HTML Makefile src objs the CHANGES conf contrib LICENSE man the README [root @ mysqlb nginx-1.13.4] # cp objs / nginx / usr / local / nginx / sbin / 6. View the current version [ @ mysqlb nginx-1.13.4 root] # / usr / local / nginx / sbin / nginx -v nginx Version: nginx / 1.13.4
method one:
[root@mysqlb nginx-1.13.4]# make upgrade
Method Two:
1. Review of nginx pid
[root@mysqlb ~]# ps -ef | grep nginx root 64600 1 0 16:47 ? 00:00:00 nginx: master process /usr/local/ngin /sbin/nginxnginx 64601 64600 0 16:47 ? 00:00:00 nginx: worker process root 70426 58718 0 17:21 pts/3 00:00:00 grep --color=auto nginx
2. Perform kill -USR2 pid
[root@mysqlb ~]# kill -USR2 64600 [root@mysqlb ~]# ps -ef | grep nginx root 64600 1 0 16:47 ? 00:00:00 nginx: master process /usr/local/ngin /sbin/nginxnginx 64601 64600 0 16:47 ? 00:00:00 nginx: worker process root 70428 64600 0 17:22 ? 00:00:00 nginx: master process /usr/local/ngin /sbin/nginxnginx 70429 70428 0 17:22 ? 00:00:00 nginx: worker process root 70432 58718 0 17:23 pts/3 00:00:00 grep --color=auto nginx
At this point, nginx examples of old and new versions will run at the same time, co-processing request input to phase out the older version of nginx instance, must send WINCH signal to the old master process, then it will begin the process of work to close normal:
3. Perform kill -WINCH pid
[root@mysqlb ~]# kill -WINCH 64600 [root@mysqlb ~]# ps -ef | grep nginx root 64600 1 0 16:47 ? 00:00:00 nginx: master process /usr/local/ngin /sbin/nginxroot 70428 64600 0 17:22 ? 00:00:00 nginx: master process /usr/local/ngin /sbin/nginxnginx 70429 70428 0 17:22 ? 00:00:00 nginx: worker process root 70434 58718 0 17:24 pts/3 00:00:00 grep --color=auto nginx
If you try to upgrade successfully, but also want to keep the new server, send QUIT signal to the old master process it quits, leaving only the new server is running.
4. Perform kill -QUIT pid
[root@mysqlb ~]# kill -QUIT 64600 [root@mysqlb ~]# ps -ef | grep nginx root 70428 1 0 17:22 ? 00:00:00 nginx: master process /usr/local/ngin /sbin/nginxnginx 70429 70428 0 17:22 ? 00:00:00 nginx: worker process root 70436 58718 0 17:26 pts/3 00:00:00 grep --color=auto nginx
The old version is not performed prior to the fourth step can also be restored
[root@vlnx251101 ~]# rm -rf /usr/local/nginx/sbin/nginx [root@vlnx251101 ~]# cp /usr/local/nginx/sbin/nginx.bak /usr/local/nginx/sbin/nginx [root@vlnx251101 ~]# kill -HUP 44610 [root@vlnx251101 ~]# ps -ef | grep nginx root 44610 1 0 12:40 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx root 74746 44610 0 14:38 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx nginx 74747 74746 0 14:38 ? 00:00:00 nginx: worker process nginx 77990 44610 0 14:53 ? 00:00:00 nginx: worker process [root@vlnx251101 ~]# kill -QUIT 74746 [root@vlnx251101 ~]# ps -ef | grep nginx root 44610 1 0 12:40 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx nginx 77990 44610 0 14:53 ? 00:00:00 nginx: worker process
Two. LuaJIT i.e. using Lua code written in C language interpreter
1. Download LuaJIT
Install yum install wget
[root@mysqlb ~]# wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz
2. Compile, install
[root@mysqlb ~]# tar xf LuaJIT-2.0.5.tar.gz [root@mysqlb ~]# cd LuaJIT-2.0.5/ [root@mysqlb LuaJIT-2.0.5]# make install PREFIX=/usr/local/luajit [root@mysqlb LuaJIT-2.0.5]# echo "/usr/local/luajit/lib/" > /etc/ld.so.conf.d/usr_local_luajit_lib.conf [root@mysqlb LuaJIT-2.0.5]# ldconfig (刷新配置文件)
3. Set Environment Variables
[root@mysqlb LuaJIT-2.0.5]# export LUAJIT_LIB=/usr/local/luajit/lib [root@mysqlb LuaJIT-2.0.5]# export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0
4.Lua program
[root@mysqlb LuaJIT-2.0.5]# vim hello.lua
[root@mysqlb LuaJIT-2.0.5]# cat hello.lua
print ("Hello World")
[root@mysqlb LuaJIT-2.0.5]# lua hello.lua
Hello World
[root@mysqlb LuaJIT-2.0.5]# lua

> print ("Hello World")
Hello World
>
5. Download NDK and Lua_module
[root@mysqlb ~]# tar xf ngx_devel_kit-0.3.0.tar [root@mysqlb ~]# tar xf lua-nginx-module-0.10.10.tar [root@mysqlb ~]# tar xf nginx-1.13.4.tar [root@mysqlb ~]# cd nginx-1.13.4 [root@mysqlb nginx-1.13.4]# make clean rm -rf Makefile objs [root@mysqlb nginx-1.13.4]# ./configure --prefix=/usr/local/nginx1134 --user=nginx --gro up=nginx --with-http_ssl_module --with-http_stub_status_module --with-file-aio --with-http_dav_module --with-pcre=../pcre-8.40 --add-module=../ngx_devel_kit-0.3.0 --add-module=../lua-nginx-module-0.10.10 [root@mysqlb nginx-1.13.4]# make && make install
6. Change profile
[root@mysqlb nginx-1.13.4]# vim /usr/local/nginx1134/conf/nginx.conf
[root @ mysqlb nginx-1.13.4] # echo 'ngx.say ( "Hello World")'> /tmp/hello.lua
do remember killing 80-port process
[root @ mysqlb nginx-1.13.4] # pkill Nginx
[@ mysqlb Nginx the root-1.13.4] # / usr / local / nginx1134 / sbin / Nginx -C / usr / local / nginx1134 / the conf
/nginx.conf
7. results
[root@mysqlb nginx-1.13.4]# curl 192.168.88.101/test1 Hello world [root@mysqlb nginx-1.13.4]# curl 192.168.88.101/test2 Hello World
