centos7通过编译源码的方式安装nginx

环境:

  • 系统:digitalocean CentOS 7.4 x64

为了使Nginx能够启用http/2,需要通过源码的方式安装nginx,并指定--with-openssl的版本在1.0.2版本以上,具体安装步骤如下:

安装可选依赖

sudo yum -y install  gcc gcc-c++ ncurses-devel perl perl-devel perl-ExtUtils-Embed libxslt libxslt-devel libxml2 libxml2-devel gd gd-devel GeoIP GeoIP-devel

下载nginx

$ cd /usr/local/src/
$ sudo wget http://nginx.org/download/nginx-1.12.2.tar.gz && sudo tar zxvf nginx-1.12.2.tar.gz


源码安装必备依赖

nginx 需要依赖3个库,分别是:PCRE, zlib and OpenSSL,接下来我们从源码进行安装:

$ cd /usr/local/src/

# PCRE version 8.40
$ sudo wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz && sudo tar xzvf pcre-8.40.tar.gz

# zlib version 1.2.11
$ sudo wget https://www.zlib.net/zlib-1.2.11.tar.gz && sudo tar xzvf zlib-1.2.11.tar.gz

# OpenSSL version openssl-1.1.0h
$ sudo wget https://www.openssl.org/source/openssl-1.1.0h.tar.gz && sudo tar xzvf openssl-1.1.0h.tar.gz

删除不需要的源码包

$ sudo rm -rf *.tar.gz

编译

cd nginx-1.12.2/

sudo ./configure --prefix=/etc/nginx \
            --sbin-path=/usr/sbin/nginx \
            --modules-path=/usr/lib64/nginx/modules \

            --with-openssl-opt=no-nextprotoneg \
            --with-debug

sudo make 
sudo make install

创建软链

sudo ln -s /usr/lib64/nginx/modules /etc/nginx/modules

这样就可以在nginx的配置文件中像这样加载动态模块:load_module modules/ngx_foo_module.so;

查看编译信息

sudo nginx -V

修改/etc/nginx/nginx.conf

去掉 user nobody;一行的注释。

检查配置是否存在潜在错误

## 执行检查可能会报错
sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: [emerg] mkdir() "/var/cache/nginx/client_temp" failed (2: No such file or directory)
nginx: configuration file /etc/nginx/nginx.conf test failed

## 如果报上面的错误,则执行下面的代码
sudo mkdir -p /var/cache/nginx && sudo nginx -t

创建nginx系统服务单元

编辑文件:

sudo vi /usr/lib/systemd/system/nginx.service

将下面的内容复制进去:

[Unit]
Description=nginx - high performance web server
Documentation=https://nginx.org/en/docs/
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/var/run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t -c /etc/nginx/nginx.conf
ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID

[Install]
WantedBy=multi-user.target

启动nginx并设置开机启动

sudo systemctl start nginx.service && sudo systemctl enable nginx.service

检查系统重启是否会自动重启

sudo systemctl is-enabled nginx.service

相关错误及解决办法

1.getpwnam("nginx") failed

解决办法:编辑/etc/nginx/nginx.conf,将user nobody的注释去掉既可,参考:http://www.iitshare.com/install-nginx-nginx-emerg-getpwnam-www-failed-error.html。

2.执行sudo nginx -t报错nginx: [emerg] mkdir() "/var/cache/nginx/client_temp" failed (2: No such file or directory)

解决办法:sudo mkdir -p /var/cache/nginx && sudo nginx -t
