编译安装nginx1.18

# 安装编译依赖
yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
​
useradd -s /sbin/nologin nginx
tar zxvf nginx-1.18.0.tar.gz
cd nginx-1.18.0
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module
make
make install
​
# 启动nginx
/usr/local/nginx/sbin/nginx 

平滑升级至1.22版本

tar zxvf nginx-1.22.0.tar.gz
​
## 注意：一些操作都是在该目录完成
cd nginx-1.22.0
# 配置
# --pid-path 指定nginx的pid文件存放位置
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-stream --pid-path=/usr/local/nginx/logs/nginx.pid
# 编译
make
​
# 备份旧版本，复制新版本
mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old
cp objs/nginx /usr/local/nginx/sbin/
chown nginx:nginx /usr/local/nginx/sbin/nginx
​
# 升级
make upgrade
​
​
## 以下是回显可以参考一下
[root@node2 nginx-1.22.0]# make upgrade
/usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
sleep 1
test -f /usr/local/nginx/logs/nginx.pid.oldbin
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin` 
[root@node2 nginx-1.22.0]# /usr/local/nginx/sbin/nginx -v
