Nginx/1.14.2编译安装使用Jemalloc

admin

服务器信息：
[root@centos8 ~]# cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)
[root@centos8 ~]#
[root@centos8 ~]# uname -r
4.18.0-193.el8.x86_64


Jemalloc是内存分配器，可以提升Nginx的性能。


安装Jemalloc：
dnf -y install bzip2 gcc-c++ make lsof

tar -jxvf jemalloc-5.2.1.tar.bz2
cd jemalloc-5.2.1
./configure
make && make install

ldconfig
ln -sf /usr/local/lib/libjemalloc* /usr/lib/





安装Nginx：（编译的时候使用Jemalloc）
dnf -y install pcre-devel openssl-devel zlib-devel gcc-c++ make psmisc

useradd -M -s /sbin/nologin nginx
tar -zxvf nginx-1.14.2.tar.gz
cd nginx-1.14.2

./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module  --with-http_ssl_module --with-ld-opt='-ljemalloc' && make && make install

ln -sf /usr/local/nginx/sbin/nginx /usr/sbin/



### 开机自动运行Nginx
[root@centos8 ~]# vi /etc/init.d/nginx
#!/bin/bash
#chkconfig: 35 99 20
#description:Nginx Service Control Script

case "$1" in
start)
/usr/local/nginx/sbin/nginx
;;
stop)
/usr/bin/killall -s QUIT nginx
;;
restart)
$0 stop
$0 start
;;
*)
echo "Usage:$0 {start|stop|restart}"
exit 1
esac
exit 0


[root@centos8 ~]# chmod a+x /etc/init.d/nginx

[root@centos8 ~]# chkconfig --add nginx


启动Nginx：
[root@centos8 ~]# systemctl start nginx


开机自动启动Nginx：
[root@centos8 ~]# systemctl enable nginx
nginx.service is not a native service, redirecting to systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install enable nginx

确认开机自动启动Nginx：
[root@centos8 ~]# systemctl is-enabled nginx
nginx.service is not a native service, redirecting to systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install is-enabled nginx
enabled



查看Nginx的进程：
[root@centos8 ~]# ps aux |grep nginx |grep -v grep
root         988  0.0  0.3  64860  6828 ?        Ss   10:04   0:00 nginx: master process /usr/local/nginx/sbin/nginx
nginx        989  0.0  0.5  93752 10384 ?        S    10:04   0:00 nginx: worker process



查看Nginx的版本和编译参数：
[root@centos8 ~]# nginx -V
nginx version: nginx/1.14.2
built by gcc 8.3.1 20191121 (Red Hat 8.3.1-5) (GCC)
built with OpenSSL 1.1.1c FIPS  28 May 2019
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module --with-ld-opt=-ljemalloc



验证Nginx是否使用了Jemalloc：
[root@centos8 ~]# lsof -n |grep jemalloc
nginx      988                   root  mem       REG              253,0  6123808  201710032 /usr/local/lib/libjemalloc.so.2
nginx      989                  nginx  mem       REG              253,0  6123808  201710032 /usr/local/lib/libjemalloc.so.2
