ubuntu Install nginx from official source
cd ~ wget http://nginx.org/keys/nginx_signing.key sudo apt-key add nginx_signing.key sudo nano /etc/apt/sources.list # 添加以下两句 deb http://nginx.org/packages/ubuntu/ precise nginx deb-src http://nginx.org/packages/ubuntu/ precise nginx sudo apt-get update sudo apt-get install nginx
ubuntu Install nginx from ppa source:
sudo add-apt-repository ppa:nginx/stable sudo apt-get update sudo apt-get install nginx
ubuntu Install nginx from regular sources:
sudo apt-get install nginx
Compile and install nginx
wget http://nginx.org/packages/mainline/ubuntu/pool/nginx/n/nginx/nginx_1.5.7-1~precise_i386.deb wget http://nginx.org/download/nginx-1.5.7.tar.gz tar xzf nginx-1.5.7.tar.gz cd nginx-1.5.7
(Note: nginx1.5.7 is the mainline version and Non-stable version)
In order to facilitate development and management, I created a new png directory in the root directory, and set the directory owner to the current user, and nginx was compiled under /png/nginx/1.5.7:
sudo mkdir /png sudo chown eechen:eechen /png
I defined the running user as png:png, so I need to create a new user like this:
sudo addgroup png --system sudo adduser png --system --disabled-login --ingroup png --no-create-home --home /nonexistent --gecos "png user" --shell /bin/false
(For the command to create a new user, please refer to the pre-installed command in the official deb package. Installation script debian/preinst)
The compilation parameters refer to the deb package officially provided by nginx (visible by nginx -v).
./configure \
--prefix=/png/nginx/1.5.7 \ --sbin-path=/png/nginx/1.5.7/sbin/nginx \ --conf-path=/png/nginx/1.5.7/conf/nginx.conf \ --error-log-path=/png/nginx/1.5.7/var/log/error.log \ --http-log-path=/png/nginx/1.5.7/var/log/access.log \ --pid-path=/png/nginx/1.5.7/var/run/nginx.pid \ --lock-path=/png/nginx/1.5.7/var/run/nginx.lock \ --http-client-body-temp-path=/png/nginx/1.5.7/var/cache/client_temp \ --http-proxy-temp-path=/png/nginx/1.5.7/var/cache/proxy_temp \ --http-fastcgi-temp-path=/png/nginx/1.5.7/var/cache/fastcgi_temp \ --http-uwsgi-temp-path=/png/nginx/1.5.7/var/cache/uwsgi_temp \ --http-scgi-temp-path=/png/nginx/1.5.7/var/cache/scgi_temp \ --user=png \ --group=png \ --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-mail \ --with-mail_ssl_module \ --with-file-aio \ --with-ipv6
Note: This step installs dependent packages according to the error prompts , this is when apt is about to show its power. For example, my system has these packages installed:
sudo apt-get -y install \
build-essential \ autoconf \ libtool \ libxml2 \ libxml2-dev \ openssl \ libcurl4-openssl-dev \ libbz2-1.0 \ libbz2-dev \ libjpeg-dev \ libpng12-dev \ libfreetype6 \ libfreetype6-dev \ libldap-2.4-2 \ libldap2-dev \ libmcrypt4 \ libmcrypt-dev \ libmysqlclient-dev \ libxslt1.1 \ libxslt1-dev \ libxt-dev \ libpcre3-dev
After installing these packages, you don’t need to install them again next time you compile a new version of nginx, and it’s basically the same. Meet the configure requirements when compiling php.
Okay, after the configure is successful, you can compile and install:
time make && make install
time is mainly used to check the time taken for this compilation.
After compilation You can take a look at the size of this guy:
du -sh /png/nginx/1.5.7/sbin/nginx
5.5m /png/nginx/1.5.7/sbin/nginx
Simple environment configuration summary
Reduce the file size after nginx is compiled:
Edit the source file nginx-1.5. 7/auto/cc/gcc Remove debug information (just comment it out):
# debug # cflags="$cflags -g"
The size of the compiled main program is more than 700k, which is similar to the size of the deb package program officially provided by nginx .
In addition, if you remove some unnecessary modules when configuring, the compiled executable file will be smaller.
Of course, I need a service script to manage nginx. At this time, I can also use the official deb package provided Service script etc/init.d/nginx.
I put it in /png/nginx/1.5.7/nginx and slightly modified the values defined at the beginning (lines 13 to 19):
path=/sbin:/usr/sbin:/bin:/usr/bin desc=nginx name=nginx conffile=/etc/nginx/nginx.conf daemon=/usr/sbin/nginx pidfile=/var/run/$name.pid scriptname=/etc/init.d/$name 改为 path=/sbin:/usr/sbin:/bin:/usr/bin desc=nginx name=nginx conffile=/png/nginx/1.5.7/conf/nginx.conf daemon=/png/nginx/1.5.7/sbin/nginx pidfile=/png/nginx/1.5.7/var/run/$name.pid scriptname=/png/nginx/1.5.7/$name
Create a cache directory before starting, otherwise an error will be prompted:
mkdir /png/nginx/1.5.7/var/cache
Start nginx:
sudo /png/nginx/1.5.7/nginx start
Test page:
curl -i `hostname`
Look at the port:
sudo netstat -antp|grep nginx
Check the memory it occupies:
htop press f4 to filter nginx
You can also see similar content with top:
top -b -n1|head -n7 && top -b -n1|grep nginx
Mainly depends on the value of res, resident memory (resident), excluding the physics of swap space Memory, the unit is kb, %mem takes res as the reference object.
You can see that the total physical memory occupied by the two nginx processes is less than 2m, and the memory usage is very small.
In addition, the res value in top Corresponding to the value of rss in ps aux:
ps aux|head -n1 && ps aux|grep nginx
Also we can see that the nginx worker process has only one thread:
cat /proc/25047/status|grep threads
threads: 1
where 25047 is the nginx worker process pid No.
Make nginx a system service and start it automatically at boot:
sudo ln -s /png/nginx/1.5.7/nginx /etc/init.d/png-nginx sudo update-rc.d png-nginx defaults #开机自启动 sudo update-rc.d -f png-nginx remove # 以后不想开机自启动可以这样禁止 sudo service png-nginx reload #这样就可以用service来管理nginx服务了,比如重载配置
Finally, the main configuration file of nginx is located at /png/nginx/1.5.7/conf/nginx.conf. Configure on demand.
